China 3.5 inch lcd display 640*960 mipi ST7703 Manufacturers, Suppliers, Factory

As the name suggests, the liquid crystal display (LCD) panel uses a liquid crystal to turn pixels on and off to display specific colors.

The LCD screen itself does not emit light, and a backlight needs to be added to the back of the glass for normal display. This involves how to test the surface brightness and backlight uniformity of the LCD screen. The brightness of the LCD screen surface and backlight brightness are measured through BM -7 equipment test, the test is more accurate when the display is powered normally and displays a solid color picture.

​Our company has successfully mass-produced 2.3-inch TFT horizontal screens with a resolution of 480*360 and IPS full viewing angles, filling the long-term vacancy in the 2.3-inch horizontal screen market with only low resolution and no full viewing angles.

2.4-inch 240*320 interface SPI/RGB/MCU 2.4-inch 240*320 interface MIPI 2.4-inch 240*320 interface SPI 2.4-inch 320*480 interface MIPI/RGB 2.4-inch 480*640 interface MIPI/RGB 2.4-inch 272*480 interface RGB/MIPI 2.4-inch 272*480 interface SPI/MCU/RGB 2.4-inch 240*320 semi-transparent and semi-reflective 2.4-inch 240*320 high brightness 1000nits The above products are all IPS, using ILI9341 and ST7789 driver ICs, can be high-brightness, support customization, welcome to email consultation.

Polarizer is one of the important materials of liquid crystal display. It is a composite material made of polyvinyl alcohol (PVA) stretched film and cellulose acetate film (TAC) through multiple lamination, stretching, coating and other processes. , can realize liquid crystal display high brightness, high contrast characteristics. Polarizers account for about 10% of the cost of TFT-LCD (Thin Film Transistor Liquid Crystal Display) panels.

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.
