TFT LCD Display LCD Touchscreen for Smart Home

1. Display size: The display size of TFTLCD refers to the diagonal length of the actual visible area, in inches, abbreviated as inches (1 inch = 2.54 cm).

2. Aspect ratio: The aspect ratio is the ratio of the length to the width of the visible area of the TFTLCD, also known as the screen ratio. The aspect ratio of TFT-LCD is mainly 4:3, 5:4, 16:10 and 16:9. The ratio of 16:9 is closer to the golden ratio, which is more comfortable to the human eye. In the design of TFTLCD products, H (horizontal) usually means length, and V (vertical) means width LCD Display Module.

3. Effective display area: The effective display area refers to the total screen area that TFTLCD can display. Knowing the display size and aspect ratio of the TFT-LCD, the specific length and width of the effective display area can be calculated using Pythagoras’s law Transparent OLED.

4. Number of pixels: The resolution of TFTLCD indicates the number of luminous points that can be used for image display in the effective display area . The light-emitting points in TFTLCD are called pixels. The resolution is usually expressed in the form of multiplication, such as a resolution of 1024×768, where 1024 represents the number of pixels displayed in the horizontal direction of the effective display area, and 768 represents the number of pixels displayed in the vertical direction. The resolution reflects the total number of pixels in the effective display area. The higher the resolution, the higher the resolution of the picture. Generally, the human eye is more sensitive to the number of pixels in the vertical direction. The higher the vertical resolution, the higher the clarity of the picture TFT LCD module.


4. There are many reasons for the abnormal display of the entire TFT screen:

    For the synchronous LCD screen, you should determine whether the display settings have changed, whether the communication is normal, whether the push is normal, and then whether the reception is normal;

    For multi-threaded LCD screens, first determine the main parameters of the display: the detailed address of the hardware configuration, the total width, the aspect ratio, and whether the IP has changed. If these main parameters are appropriate, then check whether the communication is normal, and finally determine whether the operation of the TFT LCD screen is normal AMOLED.
