China 2.4 inch Industrial display 39PIN 240*320 Manufacturers, Suppliers, Factory

In addition, when designing the touch screen circuit principle, the grounding of the FPC cable can be increased, or the touch screen cable can be covered with double-sided black electromagnetic film, which can also reduce the electromagnetic interference problem of the touch screen in practical applications. Shenzhen Hongjia Technology has been professionally developing and producing 1.14-inch to 10.1-inch displays and supporting touch screens for 12 years. It has a R&D team of more than 20 people who are familiar with solving common problems in the industry and can reduce troubles for customers.

Some customers are still not very clear about the resolution of the display screen. We will explain it here. The resolution of the LCD screen refers to the number of pixels of the LCD screen, that is, the number of dot matrix, which is usually the number of pixels in the horizontal direction multiplied by the number of pixels in the vertical direction. Under the same LCD screen size, the higher the resolution dot matrix, the clearer and more delicate the display image effect is.

What are the mainstream resolutions in the 3.5-inch TFT LCD screen market?

Ordinary LCD screens use CCFL light sources, that is, cold-cathode fluorescent lamps (similar to the scanning lamps in the copy), with one on each side of the screen and a backlight on the back of the display, which is composed of fluorescent substances. The light sources on both sides can be evenly distributed on the back of the entire screen, so that the entire screen can be evenly illuminated. However, due to technical limitations, the brightness of such a display is not completely uniform, but it is difficult to find it. At the same time, the lamp also has a certain lifespan, and it will turn yellow after a long time.
