China 3.5 inch tft lcd display ST7796 Manufacturers, Suppliers, Factory

Usually, touchable LCD screens are capacitive screens, and the positioning method of the touch screen is through the electric field. Therefore, when static electricity and discharge occur, the LCD touch screen will have a "drift" screen effect, that is, the click position is offset from the actual response position.

​An LCD display module is an electronic component used for displaying characters, symbols, and graphics in a clear, easy-to-read format. It typically consists of a liquid crystal display (LCD) panel, a driver circuit board, and other supporting components, such as backlighting and a controller chip.

Shenzhen Hongjia Technology 2.3-inch long strip display, IPS material, 200*480 resolution, supports SPI/MCU/QSPI/MIPI interface, 30PIN plug-in, with capacitive touch screen.

Backlighting is used in small, light, flat-panel liquid crystal displays (LCDs) and other electronic devices that require backlighting, including handheld devices as small as the palm of your hand, and large-screen TVs. The goals of backlight design include low power consumption, ultra-thin, high brightness, uniform brightness, large area, and control of different width and narrow viewing angles. To achieve these challenging design goals with controlled cost and rapid implementation, computer-aided optical design tools must be used for design. This article introduces the characteristics of LightTools optical design and analysis software from ORA Company in the United States, which can be used to develop the most advanced backlight design applications today.

Our company has developed a 3.5-inch horizontal screen TFT with a resolution of 320*240, which can support SPI interface, 8/16-bit MCU interface, and 16/18-bit RGB interface. It can be used normally on single-chip microcomputers

In order to meet the stringent environmental temperature requirements of different customers and different product applications, our company has launched a variety of ultra-low temperature LCD screens. The operating temperature can reach -30 to 85 degrees, and the storage temperature is also -30 to 85 degrees. The wide-temperature LCD screen has picture It has the characteristics of stable quality and adaptability to harsh environmental temperatures, and can be widely used in military, telecommunications, electric power, metallurgy, machinery, CNC, petroleum, chemical industry, medical, aerospace and other fields.
