LED digital tube, TFT lcd screen, and OLED screen are three types of screens widely used in electronic devices, with significant differences in composition, technical principles, and applications.

1、 LED digital tube

Composition: The LED digital tube is composed of multiple LED light-emitting diodes, each corresponding to a part of a number or symbol on the digital tube. They are encapsulated in a transparent plastic or glass casing to form a cohesive display unit.

Technical principle: The working principle of LED digital tube is based on the luminous characteristics of LED. When current passes through an LED, the LED emits light, and the color of the light depends on the material of the LED. In a digital display, numbers, letters, or symbols can be displayed by controlling the brightness of different LEDs.

Application: LED digital tubes are widely used in various occasions that require digital display, such as electronic clocks, counters, thermometers, etc., due to their simple structure, low price, and easy control.

Advantages: Energy saving and environmental protection: LED digital tubes have higher energy saving and environmental protection characteristics compared to traditional LCD displays. Due to its use of DC drive, it has lower power consumption and does not require the use of LCD screens, making it more energy-efficient. Lower cost: Compared to some high-end display technologies, LED digital tubes have a relatively lower price and are more suitable for use in some mid to low end application scenarios. Strong customizability: LED digital tubes can display different characters through different combinations of LEDs, thus having high customizability and allowing for different designs and production according to needs.

Disadvantages: Limited display effect: Compared with TFT and OLED screens, LED digital tubes have a simpler display effect and are usually used to display numbers, letters, and simple graphics. They are not suitable for displaying high-definition videos or complex images.

2、 TFT lcd screen (Thin Film Transistor)

Composition: TFT lcd screen is composed of multiple complex components, including liquid crystal layer, backlight module, thin film transistor, color filter, polarizer, etc. The liquid crystal layer is the core part of TFT screen, used to control the transmission and obstruction of light; The backlight module provides a light source; Thin film transistors act as switching elements to control the brightness of each pixel.

Technical principle: TFT screen belongs to a type of active matrix liquid crystal display. It controls the alignment direction of liquid crystal molecules through thin film transistors, thereby controlling the amount of light transmitted. When current passes through a thin film transistor, an electric field is generated to deflect liquid crystal molecules, thereby changing the transmittance of light and achieving image display.

Application: TFT screens are widely used in high-end electronic products such as smartphones, tablets, LCD TVs, etc. due to their advantages of high definition, high color reproduction, and low energy consumption.

Advantages: High Resolution: TFT screens typically have high resolution and can present clear images and text, making them suitable for tasks such as reading, watching high-definition videos, and graphic design. Fast response time: Due to the use of LCD technology, TFT screens have a fast response time, suitable for playing dynamic content and games, reducing motion blur and ghosting. Multifunctionality: TFT screens are widely used in various electronic devices, including smartphones, tablets, televisions, computer monitors, etc., to meet different user needs. Wide viewing angle: TFT screens typically have a good viewing angle and can maintain image quality even at oblique angles.

Disadvantages: High energy consumption: TFT screens typically require a backlight source to generate brightness, which may result in higher energy consumption, especially when displaying high brightness content. Black level limitation: Compared to OLED, TFT screens may have some limitations when displaying dark black, as LCD cannot completely turn off the light source.

3、 OLED screen (Organic Light Emitting Diode)

Composition: OLED screen is composed of organic light-emitting material layer, anode, cathode, and encapsulation layer. The organic light-emitting material layer is the core part of OLED screens, and when current passes through it, the organic material emits light.

Technical principle: The working principle of OLED screens is based on the electroluminescence phenomenon of organic materials. When current passes through the organic luminescent material layer, electrons and holes recombine in the luminescent layer to produce excitons, which release energy and emit light when they decay. Each pixel of an OLED screen can independently emit light and control brightness, thus having extremely high contrast and color saturation.

Application: OLED screens are widely used in fields such as smartphones, high-end TVs, wearable devices, etc. due to their advantages of self illumination, high contrast, wide viewing angle, and low power consumption. In addition, OLED screens can also achieve curved and flexible design, providing more possibilities for product design.

Advantages: Self luminous: OLED screens emit light at each pixel, making them thinner and lighter than LCDs, and do not require a backlight source, allowing for higher contrast and deeper black color. Low power consumption: OLED screens save structures such as backlight, LCD, and color filters, resulting in lower power consumption. Flexible display: OLED screens can achieve flexible display, providing more possibilities for future electronic device design. Vibrant colors: OLED screens have higher color saturation, resulting in more vivid image colors.

Disadvantages: High cost: The production process of OLED screens is complex, so the price is relatively high. Short lifespan: OLED organic materials have a limited lifespan, typically only a few thousand hours. Risk of burn-in: OLED screens may experience burn-in when displaying static images for a long time at low brightness.

Look around you. Whether you're reading this on your smartphone, glancing at your laptop monitor, or checking the time on your smartwatch, there's a very high chance you're looking at a TFT LCD display. This technology is the workhorse behind the visual interface of countless modern devices. But what exactly is a TFT LCD, and how does it create the bright, colorful images we see every day? Let's dive in and demystify this engineering marvel.

 

tft lcd display

 

What is a TFT LCD?

 

First, let's break down the acronym:

 

LCD (Liquid Crystal Display): An LCD is a flat-panel display that uses the light-modulating properties of liquid crystals. These crystals don't produce their own light; instead, they rely on a backlight and act like tiny shutters to either block or allow light to pass through.

 

TFT (Thin-Film Transistor): This is the active matrix technology that drives the LCD. A TFT is a special type of transistor made from a thin film of semiconductor material deposited on a glass panel. For every single pixel on the screen, there are one or more of these tiny transistors.

 

So, a TFT LCD is essentially an active matrix LCD where each pixel is controlled by one to four transistors. This setup allows for faster response times, sharper images, higher contrast, and better color reproduction compared to older, passive matrix LCDs. It's the "smart" and precise way to control an LCD.

 

How Does a TFT LCD Work?

 

The magic of a TFT LCD lies in its layered structure and precise control of light. Here’s a step-by-step breakdown:

 

1. The Backlight:

The process starts with a bright white LED backlight at the rear of the display assembly. This light source is always on, providing the illumination for the entire screen.

 

2. The Polarizers:

The light first passes through a polarizing filter. This filter only allows light waves vibrating in a specific direction to pass through, creating polarized light.

 

3. The Liquid Crystal Layer:

This polarized light then reaches the layer of liquid crystals. Each pixel is made up of three sub-pixels—red, green, and blue (RGB)—each with its own transistor. By applying a precise electrical voltage via the TFT, the twist of the liquid crystals changes. This twisting action either twists the polarized light to allow it through or untwists to block it, acting like a microscopic shutter for each sub-pixel.

 

4. The Color Filter:

After passing through the liquid crystal layer, the light hits a color filter. This filter has individual red, green, and blue segments for each sub-pixel. The amount of light that passed through each sub-pixel now shines through its corresponding color filter, creating the exact shade of red, green, or blue needed.

 

5. The Second Polarizer:

Finally, the light passes through a second polarizing filter. This filter is oriented at a 90-degree angle to the first one. Its job is to analyze the light that has been altered by the liquid crystals. The combination of these two filters and the liquid crystals' twisting action ultimately determines whether light is allowed to pass through for that pixel or not.

 

Your brain blends the intense of these millions of tiny red, green, and blue sub-pixels together to perceive a single, full-color pixel. Millions of these pixels working together form the complete image on your screen.

 

Key Advantages of TFT LCDs

 

High Contrast & Image Quality: Offers sharp and vibrant images.

 

Cost-Effective: Mature manufacturing processes make them relatively inexpensive to produce.

 

Long Lifespan: LEDs have a very long operational life.

 

Reliability: Solid-state technology with no moving parts.

 

Conclusion

 

TFT LCD technology is a masterpiece of engineering that combines the precise control of thin-film transistors with the unique light-modulating properties of liquid crystals. From your phone to your TV and the dashboard in your car, this reliable, efficient, and cost-effective technology continues to be a dominant force in bringing digital information to life right before our eyes.

An LCD display, which stands for Liquid Crystal Display, is a type of flat-panel display technology that uses the light-modulating properties of liquid crystals to display images.

 

Here's a breakdown of how it generally works and its key characteristics:

 

How it works:

 

Liquid Crystals: Unlike traditional solids or liquids, liquid crystals have unique properties. Their molecules can be aligned or rotated when an electric current is applied.

 

 

Backlight: LCDs don't emit light directly. Instead, they rely on a backlight (usually LED-based in modern displays) that shines light through the display.

 

Polarizers: Before the light from the backlight reaches the liquid crystal layer, it passes through a polarizing filter that aligns the light waves in a specific direction.

 

Electrodes: A grid of electrodes surrounds the liquid crystal layer. When an electric voltage is applied to these electrodes, it causes the liquid crystal molecules to twist or untwist.

 

Light Modulation: As the liquid crystals change their orientation, they either allow or block the polarized light from passing through.

 

Color Filters (for color displays): For color LCDs, the light then passes through tiny colored filters (red, green, and blue) for each pixel. By varying the amount of light that passes through each sub-pixel, a full spectrum of colors can be created.

 

 

Image Formation: The combination of many such pixels, each controlled independently, forms the complete image on the screen.

 

Key Characteristics and Advantages:

 

Thin and Lightweight: LCDs are significantly thinner and lighter than older display technologies like Cathode Ray Tube (CRT) monitors.

 

Low Power Consumption: They consume less power, making them ideal for portable devices and energy-efficient electronics.

 

Versatility: LCDs are used in a wide range of devices, from small digital watches and calculators to large televisions, computer monitors, and smartphones.

 

Sharp Image Quality: They can produce sharp and clear images, especially high-resolution models.

 

Flat Panel: Their flat design makes them suitable for modern, sleek device aesthetics.

 

In essence, an LCD display manipulates light rather than emitting it directly, using the unique properties of liquid crystals to control the passage of light and create images.

It's a common misconception that "LCD" and "LED" are completely separate and competing display technologies. In reality, almost all modern "LED" displays for TVs, monitors, and smartphones are actually a type of LCD display that uses LED backlighting.

 

Here's the crucial clarification:

 

LCD (Liquid Crystal Display): This refers to the core technology that uses liquid crystals to control the passage of light for each pixel. Liquid crystals don't emit their own light, so they need a light source behind them.

 

 

LED (Light Emitting Diode): This refers to the type of light source used for the backlight.

 

The "LCD vs. LED" distinction you often hear is typically comparing:

 

Older LCDs with CCFL (Cold Cathode Fluorescent Lamp) backlights: These were the original LCD displays, using fluorescent tubes for illumination.

 

Modern LCDs with LED backlights (often just called "LED TVs" or "LED monitors"): These replaced CCFLs with more efficient and controllable LED arrays.

 

So, when someone asks "Why is LCD better than LED?", they might be thinking of:

 

Cost: Traditional CCFL-backlit LCDs were generally cheaper to produce than early LED-backlit LCDs. While the price gap has significantly narrowed, and often LED-backlit LCDs are now the standard and very affordable, for certain specialized, very large-scale displays, there might still be cost differences.

 

Specific Niche Applications: In some very specific industrial or niche applications, an older CCFL-backlit LCD might still be used if extreme uniformity across the entire panel at a very low cost is paramount, and the other benefits of LED backlighting aren't as critical. However, this is becoming increasingly rare.

 

Misunderstanding of Terminology: The most common reason is simply a misunderstanding that "LED" is a completely different display technology, when it's actually an improvement in the backlight of an LCD.

 

Why LED Backlighting is generally "better" for LCDs (and why the market shifted):

 

When comparing modern LED-backlit LCDs to older CCFL-backlit LCDs, the LED versions offer significant advantages:

 

Energy Efficiency: LEDs consume less power, leading to lower energy bills and a more environmentally friendly product.

 

Thinner Design: LEDs are smaller and more versatile, allowing for much thinner display panels.

 

Improved Picture Quality (especially with local dimming):

 

Higher Contrast: With LED backlighting, especially Full-Array Local Dimming (FALD), specific zones of LEDs can be dimmed or brightened independently. This allows for much deeper blacks and brighter whites in different areas of the screen simultaneously, greatly improving contrast compared to CCFLs which illuminate the entire screen uniformly.

 

 

Better Brightness: LEDs can achieve higher peak brightness levels, which is crucial for HDR (High Dynamic Range) content and viewing in bright environments.

 

Better Color: LED backlighting can enable a wider and more accurate color gamut.

 

Longer Lifespan: LEDs generally have a longer operational lifespan than CCFLs.

 

No Mercury: CCFLs contain mercury, which is a hazardous material. LEDs are mercury-free.

 

The "True" LED Display (Direct View LED / MicroLED):

 

It's important to note there's another, more advanced display technology called Direct View LED (dvLED) or MicroLED. In these displays, the LEDs themselves are the pixels, emitting their own light directly, similar to OLED. These displays are typically used for very large video walls, stadium screens, or very high-end, large-format consumer displays. They offer incredible brightness, contrast, and seamless modularity, but are currently much more expensive than OLED or LCD.

 

 

In summary: When people talk about "LED" displays in the consumer market (TVs, monitors), they are almost always referring to LCD displays with LED backlighting. This technology is generally superior to older CCFL-backlit LCDs in most aspects. There are very few scenarios where a traditional CCFL-backlit LCD would be considered "better" than an LED-backlit LCD in today's market.

Over my 16 years of experience, clients often ask: What's the best brand of LEDs? Are well-known brands the best choice? Or are generic brands unworthy of use?

I believe that the term "brand effect" exists in any industry, and our LED industry is no exception.

Here, I summarize a few points based on my personal work experience.

The core technology of LED was invented in 1962 and was used for lighting purposes in the 1990s. After decades of development, it is a very mature technology. Almost all large factories have sufficient technical support to make LED chips. Generally speaking, there is not much difference in the quality of the led chips produced by everyone.

We conducted a set of comparative experiments using RGBW LEDs as a reference.

On the left are internationally renowned brands, and on the right are domestically produced LEDs (to avoid legal liability, we cannot specify the specific brands). Using the same 20-degree lens, the results are shown below.


From the above picture we can see that the lighting effect is almost the same. Left LED lamp is brighter a little than right one. This is a very small difference that can be almost ignored by us. So if the budget is not high, we can suggest customers to replace the well-known brand lamp beads with domestic ones.

But we cannot deny that after our long-term statistics, We can see other difference after using the finished products for a few years by customers.

That is, the brand LED chips have stronger resistance to light decay and aging. In addition, well-known LED chips are more capable of resisting the impact of current and voltage instability.

Of course, these points can only be reflected during the long-term use of the finished lamps or when encountering various emergencies.

These gaps are also very small, sometimes like the difference between 99 and 100. Therefore, if the budget is limited, we often recommend customers to use domestic LED chips.

Everyone is welcome to share more experiences and opinions. We are Rise Optoelectronics Co., Ltd, which is a professional outdoor lighting designer and manufacturer with 16 years of production experience, especially underwater lighting.
