TFT Screen Technology
TFT screens use liquid crystals as an optical material to control the transmission of light through the liquid crystals by adjusting the alignment of the liquid crystals with an electric field, thus realizing the display of images.
Each pixel point is equipped with a thin-film transistor to control the on-off state of the liquid crystal, thus precisely controlling the brightness and color of each pixel.
Most TFT screens have one or more backlight sources on the back of the screen that provide a light source to illuminate the liquid crystal layer. These backlight sources can be LEDs (light emitting diodes) or fluorescent lamps.
The TFT screen is able to display rich, true-to-life colors because each pixel can be precisely controlled. This makes it excellent for viewing pictures, videos and games.
TFT screens are more responsive and suitable for displaying motion pictures and videos without dragging or ghosting.
The TFT screen supports high-resolution displays that provide clear and detailed images, allowing users to enjoy clearer content.
The TFT screen offers a wide viewing angle, so even when viewed from the side or at an oblique angle, the image does not suffer from color distortion or loss of brightness.
The lower manufacturing cost of TFT screens compared to some of the more advanced display technologies (e.g. OLED) makes it more competitive for large-scale applications.
TFT screens occupy an important place in modern consumer electronics due to their good color performance, fast response time, high resolution, and cost-effectiveness.TFT screens are a reliable, proven, and affordable option that meets the needs of most users.
AMOLED
AMOLED screens use organic materials as light-emitting layers that emit light when excited by an electric current. As a result, each pixel point is self-illuminated and does not require a backlight.
Each pixel point has a separate thin-film transistor (TFT) acting as a driver to control the brightness and color of the pixel. This active matrix design allows AMOLED screens to control each pixel more precisely.
AMOLED screens are able to achieve very high contrast ratios because black pixels can be completely turned off and bright pixels can be very bright. This results in a more vivid image display with richer colors and deeper blacks.
AMOLED screens are very responsive and suitable for displaying dynamic content such as videos and games. This is because its pixels can quickly switch brightness and color.
When displaying black or near-black content, AMOLED screens are able to turn off the black pixels, which greatly reduces power consumption. This makes AMOLED screens more energy efficient in applications that display black backgrounds.
AMOLED screens can be manufactured in a flexible or curved form, which opens up a variety of innovative design possibilities. For example, smartwatches with flexible screens can be manufactured, or cell phones with curved screens can be realized.
The AMOLED screen has a wide viewing angle, so the color and brightness of the image remains relatively stable even when viewed from the side or at an oblique angle.
Because they don’t require a backlight, AMOLED screens can be manufactured very thin and are relatively lightweight, making the devices lighter.
AMOLED screens are widely used in a variety of electronic products due to their excellent color performance and high contrast ratio, including:
Smartphones: many high-end cell phones use AMOLED screens to provide superior display and longer battery life.
Smartwatches: Some smartwatches also utilize AMOLED screens, providing sharper displays and lower power consumption.
Tablets: Some high-end tablets also use AMOLED screens to provide a better visual experience.
