TFT LCD displays and modules are an important part of electronic display technology. They combine thin film transistor (TFT) and liquid crystal display (LCD) technology to achieve high-quality image display. The following is a detailed explanation of TFT LCD displays and modules:
TFT LCD (Thin Film Transistor-Liquid Crystal Display) is a thin film transistor liquid crystal display, which is an active matrix liquid crystal display technology. It has a thin film transistor on each pixel to control the rotation of liquid crystal molecules to display images.
High resolution: Since each pixel is controlled by an independent TFT, higher resolution can be achieved.
High brightness: TFT LCD can provide higher brightness, making the image clearer and brighter.
High contrast: By precisely controlling the rotation of liquid crystal molecules, TFT LCD can show higher contrast, making the image more layered.
Bright colors: Support 16-bit true color display (65536 colors), natural color transition, and more vivid pictures.
TFT LCD displays are widely used in electronic products such as televisions, mobile phones, computers, and tablets, becoming one of the most mainstream LCD displays at present.
1.Definition
TFT LCD module is a component that integrates TFT LCD display, drive circuit, backlight system, etc. It can be directly connected to the main control device such as microcontroller (MCU) to realize image display and control.
TFT LCD display: responsible for displaying images and texts.
Drive circuit: includes gate driver and source driver, which are used to control the rotation of liquid crystal molecules and the display of images.
Backlight system: provides backlight source so that the display can be clearly seen in dark environments.
Interface circuit: includes interfaces such as data line and control line, which are used to connect and communicate with the main control device.
The working principle of TFT LCD module is to scan the pixels on the screen line by line through the gate driver, and the source driver outputs the corresponding voltage signal to each pixel according to the pixel data stored in the internal GRAM (Graphics RAM). These voltage signals control the rotation direction of the liquid crystal molecules, thereby changing the transmittance of light and realizing the display of images.
TFT LCD modules usually support a variety of instruction sets and control methods, including hard reset, initialization sequence, write GRAM, read GRAM, etc. These instructions and control methods are sent to the control circuit of the TFT LCD module through the main control device such as MCU to realize the control and adjustment of the display content.
TFT LCD displays and modules are important components of electronic display technology. They combine the advantages of TFT and LCD technology to achieve high-quality image display. TFT LCD displays have the characteristics of high resolution, high brightness, high contrast and bright colors, and are widely used in various electronic products. The TFT LCD module integrates these features and realizes connection and control with the main control device through a simple interface and instruction set.
