The parameters of the LCD display specification are important indicators for evaluating the performance of the display. Next, let's take a look at how to view and understand the parameters of the LCD display specification:

1. Size and resolution

1) Size: Usually measured in inches, it represents the length of the diagonal of the screen. Different sizes of displays are suitable for different application, such as mobile phone screens, tablet screens, laptop screens, etc.

2) Resolution: It represents the number of pixels on the screen, usually expressed in the of "width x height", such as 1920 x 1080. The higher the resolution, the clearer the displayed image.

2. Display technology

1) Type: Such as TFT-LCD (Thin Film Transistor Liquid Crystal Display) and IPS-LCD (In-Plane Switching Liquid Display), etc. Different types have different characteristics and application scenarios.

2) Brightness: Measured in nits, it indicates the intensity of light emitted by the screenThe higher the brightness, the better the screen's visibility under strong light.

3) Contrast: It represents the ratio of the brightness of the brightest area to the darkest on the screen. The higher the contrast, the clearer the displayed image and the more vivid the colors.

3. Interface type

1) Such as LVDS, DSI, DBI, DPI, etc. Different interface types have different transmission rates and compatibility.

2) of pins: Indicates the number of pins on the interface, which is related to the interface type. IV. Timing characteristics 1. Frame rate (Frame RateIndicates the number of times the screen is refreshed per second, usually measured in Hertz (Hz). The higher the frame rate, the smoother the displayed image. . Pixel clock frequency: Indicates the clock frequency of pixels when the screen is refreshed. Different models of displays have different pixel clock frequencies.

4. Sequential characteristics

1) Frame Rate: It represents the number of times the screen is refreshed per second, usually measured in Hertz (Hz). The higher the rate, the smoother the displayed image.

2) 2. Pixel Clock Frequency: It represents the clock frequency of pixels when the screen is refreshed. Different models of displays have different clock frequencies. 5. Signal Timing Diagram 1. LCD Timing Diagram: It shows the timing and polarity information of the signal. It is of great reference value for and setting the display parameters.

5. Signal timing diagram

It shows the timing and polarity information of the signals. It is of great reference value for debugging setting the display parameters.

6. Other Parameters

1) Viewing Angle: It indicates the range within which the screen content is still clearly visible when observed from the center the screen to the left and right or up and down. The larger the viewing angle, the better the screen's visibility.
