"TFT" stands for Thin-Film Transistor. Each pixel is controlled by a dedicated transistor. This allows for faster response times and better contrast. It's the technology that has powered everything from laptops to smartphones for decades. Why does it matter now? Cost-Effectiveness: TFT LCD technology is mature and highly scalable. This makes it an incredibly cost-effective option for mass production. A report by IHS Markit found that the production cost of a standard TFT LCD panel is 30% lower than that of an OLED panel of the same size. Excellent Brightness: TFT LCDs are known for their high brightness, thanks to their dedicated backlighting. This makes them ideal for use in direct sunlight or bright environments, such as outdoor kiosks or car dashboards. Long Lifespan: The technology is very durable. A TFT LCD panel can operate for over 50,000 hours, which is a major advantage for industrial or medical applications that require long-term reliability. In short, while new technologies are emerging, TFT LCD remains a dominant force. Its affordability, brightness, and durability make it a go-to choice for a wide range of applications. It's a proven technology that continues to deliver value.

AMOLED
AMOLED
Originating from OLED display technology—Organic Light-Emitting Diodes—it features self-emissive properties. It uses an extremely thin layer of organic material coated onto a glass substrate. When an electric current passes through, these organic materials emit light.   Working Principle AMOLED is based on organic light-emitting materials. Thousands of tiny light sources that can emit only one of the three colors—red, green, or blue—are arranged in a specific pattern on the screen substrate. When voltage is applied, they emit red, green, or blue light. This voltage control relies on TFT (Thin-Film Transistor) technology. By adjusting the proportions of the three primary colors, various colors can be produced.   Advantages   Wide Color Gamut The color gamut refers to the range of colors a display can reproduce. Industry standards include NTSC, sRGB, and Adobe RGB color gamuts. For example, the iPad Air can display about 96% of the sRGB gamut, while Super AMOLED screens can reach close to 100% NTSC, which surpasses sRGB and is closer to the higher Adobe RGB standard (as shown in diagrams comparing the sRGB triangle). A wide color gamut allows the screen to display richer colors and reproduce more real-world hues. More importantly, it enhances contrast, enabling the display to show shadows closer to true black. In traditional Chinese culture, the five “primary” colors are blue-green (cyan), yellow, red, white, and black, symbolizing orthodoxy and nobility. Thanks to its exceptional color range, AMOLED technology can vividly reproduce these colors. For instance, its rendering of sunlight-like yellow or the life-representing cyan between blue and green is especially impressive.   High Contrast Compared to traditional TFT displays, AMOLED can display deep, solid blacks, while TFT displays appear more dark gray. AMOLED also produces pure white, resulting in clearer and more transparent visuals.   Ultra-thin Design AMOLED displays are thinner than LCD screens. LCDs contain a backlight, color filters, a backlight module, and liquid crystal layers, while AMOLED, being self-emissive, does not require these components. Integrated touch technology also makes AMOLED screens thinner and lighter. The world’s first AMOLED integrated touch display debuted in 2010 and was used in premium smartphones.   Outdoor Readability Reading maps or addresses on your phone under strong sunlight is possible with AMOLED. Outdoor readability is proportional to chroma × brightness, and OLED chroma is about 1.7 times that of LCD. This gives AMOLED displays excellent outdoor readability, allowing colors to remain clear under bright sunlight and providing better viewing angles for outdoor reading.   Lower Power Consumption AMOLED screens consume significantly less power than traditional LCDs because each pixel can be individually controlled without a constant backlight. For example, when browsing white-background websites like Baidu, most pixels emit 100% brightness. But when playing dark-scene videos, pixels emit much less light. LCDs, by contrast, always emit 100% backlight brightness and only control brightness locally by rotating liquid crystal molecules. AMOLED pixels can adjust their own brightness independently, meaning they don’t all have to emit at 100% brightness—this saves energy. Even while playing videos or multimedia content, battery drain is minimal. In emergencies, activating an ultra power-saving mode that reduces pixel use to 10% can extend phone usage up to 24 hours.

Transflective Display
Transflective Display
  Transflective screen, also known as a transflective display or semi-transmissive/semi-reflective screen, is a display technology that combines both reflective and transmissive properties. It uses a mirror-like reflective film instead of a traditional reflector, allowing the front of the screen to reflect ambient light while maintaining transparency on the back to let backlight pass through. This type of screen is widely used in aircraft instruments, automotive devices, outdoor portable electronics, and high-end smartphones.   The surface of the screen is coated so that both transmitted and reflected light account for 50% each. In bright environments, it enhances visibility through reflection, while in low-light conditions, the backlight provides illumination. This enables adaptive display performance based on ambient lighting conditions.   The secret of a transflective screen lies in its semi-reflective film. This is similar to the glass used on certain buildings, some sunglasses, or automotive window tints. The front side acts like a mirror—reflecting sunlight to provide a readable display under bright outdoor conditions. Meanwhile, the back side is see-through, allowing the screen’s backlight to pass through. In a transflective display, the traditional reflector on the back of a reflective screen is replaced with a mirror-like reflective film.      This film appears as a mirror from the front, but from the back, it’s transparent—essentially a piece of glass that reflects and transmits light. Combined with a fully transmissive backlight, a transflective screen becomes a hybrid of reflective and transmissive display technologies.   The characteristic of the semi-reverse semi-translucent screen is that the backlight brightness automatically adapts to the outdoor environment. The stronger the outdoor sunlight, the stronger the reflected backlight (sunlight) from the reflective film will be. Even the strongest outdoor light intensity is not a problem. The stronger the ambient light, the stronger the reflected backlight will be. In the outdoors, it can completely do without additional backlight lighting equipment, so it saves much power compared to the fully transparent screen, and the display effect is also much better.

Principle of Capacitive Touch Screen
Principle of Capacitive Touch Screen
  The structure of a capacitive touch screen mainly consists of a transparent conductive film layer coated on a glass screen, covered by a protective glass layer on top. This double-glass design thoroughly protects the conductive layer and sensors.   In addition, narrow electrodes are coated along the four edges of the additional touch screen, creating a low-voltage AC electric field within the conductive material. When a user touches the screen, a coupling capacitance is formed between the user's finger and the conductive layer due to the human body's electric field. The current generated from the electrodes flows toward the touch point, and its strength is proportional to the distance between the finger and each electrode. The controller behind the screen calculates the ratio and strength of the current to accurately determine the touch location. The double-glass design of the capacitive touch screen not only protects the conductor and sensors, but also effectively shields the screen from external environmental factors. Even if the screen is contaminated with dirt, dust, or grease, it can still accurately detect the touch location.    Capacitive touch screens offer better light transmittance and clarity compared to 4-wire resistive screens, though not as good as surface acoustic wave or 5-wire resistive screens. However, capacitive screens suffer from severe glare. The four-layer composite design used in capacitive technology results in uneven transmittance across different light wavelengths, causing color distortion. Reflections between layers also lead to blurred images and characters.    Fundamentally, capacitive screens treat the human body as one electrode of a capacitor. When a conductor comes close enough to generate sufficient capacitance with the ITO working surface, the resulting current may cause the screen to malfunction. While capacitance is inversely proportional to distance, it is directly proportional to the contact area and also depends on the dielectric constant of the medium. Therefore, large conductive surfaces like a palm or handheld metal object near the screen can cause false touches even without direct contact—especially in humid conditions. For example, simply resting your hand on the monitor, placing your palm within 7 cm, or your body within 15 cm of the screen may trigger false input.    Another drawback of capacitive screens is that they do not respond when touched with gloved hands or non-conductive objects due to the presence of more insulating material. The most significant issue with capacitive touch screens, however, is drift. Changes in environmental temperature, humidity, or electric fields can cause position drift and lead to inaccurate touches. For instance, drift can occur as the monitor heats up after being turned on, when the user’s body comes close to the screen, or even when large objects are moved nearby. If someone gathers around the screen while it’s being used, it can also lead to drift.    The root cause of this drift is an inherent technical flaw. Although environmental potential surfaces (including the user's body) may be farther from the screen than the finger, their larger area greatly affects touch position detection. Moreover, many theoretically linear relationships are actually nonlinear. For example, users with different body weights or finger moisture levels absorb varying amounts of current, and the relationship between total current change and individual electrode current changes is nonlinear. Capacitive screens use a custom four-corner coordinate system that lacks a fixed origin. When drift occurs, the controller cannot detect or correct it. After the analog-to-digital conversion at the four corners, the calculation of the X and Y coordinates in a Cartesian system based on the four current values is complex. Without a fixed origin, capacitive screen drift is cumulative, and frequent recalibration is required on-site. While the outer silica glass layer of the capacitive screen is highly scratch-resistant, it is vulnerable to impacts from fingernails or hard objects. A small chip can damage the ITO layer within. Whether the inner ITO layer is damaged during use, installation, or transport, the capacitive screen will no longer function properly.
