China 3.17 inch IPS High Brightness display mcu Manufacturers, Suppliers, Factory

HJ1800-01, a 1.8-inch round LCD with IPS, full viewing angle, 360*360 resolution, and a contrast ratio of 1200. It supports multiple interfaces (SPI/MCU/QSPI/MIPI) via the IM port, and supports an ultra-wide operating temperature range of -30°C to 80°C. The driver IC is the ST77916, and standard ICs are available for a long time. This 1.8-inch round LCD features a capacitive touchscreen and I2C interface. The touchscreen is laminated to the LCD for easy debugging.

At present, our company has 3 fully automatic FOG production lines and 3 fully automatic backlight assembly lines, with a monthly production capacity of 800K. Shenzhen Hongjia Technology has 12 years of industry experience, specializing in R&D, production and sales of 1.14-inch to 15-inch display screens and matching touch screens. Customers are welcome to email for consultation.

TN LCD screen glass has high transmittance. Under the same backlight conditions, TN will have higher brightness. TN glass cost is relatively cheap, which is more cost-effective for customers with price requirements; IPS is better than TN in terms of viewing angle, display effect and other parameters, but the unit price is relatively higher. Customers need to choose according to the positioning of their products. Shenzhen Hongjia Technology specializes in the production of 1.14-inch to 10.1-inch LCD screens and matching touch screens. Both TN and IPS are available, with complete sizes and multiple interfaces. Customers are welcome to email for consultation.

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.

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.

LCD screen itself has problems. If it is indeed the screen itself that is at fault after testing with relevant instruments, in addition to replacing a new LCD screen, the device-related software should be debugged and optimized so that the screen can work with the motherboard's CPU. The best way is to increase the OSC frequency of the IC and see how the LCD screen flickers. Of course, if the TFT LCD screen has separate row and column drivers, you can also adjust it by setting the driver chip.
