Latest company news about What is TFT LCD true color Screen?

TFT is commonly known as “true color” because it has higher contrast and richer colors than TN-LCD, and the screen updates faster. The main feature of TFT-LCD, as opposed to TN, is one semiconductor switch per pixel.

 

Due to each pixel can be directly controlled by point pulses, each node is relatively independent and can be controlled continuously.

 

It not only improves the response speed of the display screen, but also accurately controls the display color level, making the color of the TFT LCD true color screen more realistic.

 

What are the main structures of TFT true color screen?

  • Fluorescent tube

  • Light guide plate

  • Polarizer

  • Filter plates

  • Glass substrate

  • Alignment film

  • Liquid crystal material

  • Thin film transistor

 

What are the advantages and disadvantages of true color display?

 

Advantage

  • High brightness

  • High contrast

  • Strong layering

  • Bright colors

 

Disadvantage

  • High power consumption

  • High cost

 

Generally, the response time of TFT is relatively fast, about 80 milliseconds, and the viewing angle is generally about 130 degrees. Mainly used for high-end products.

 

Hongguang Displays a new generation of TFT true color screens that support 65,536 colors, and some even support 160,000 colors. Its advantages are high reliability, high cost performance and distinctive features
