China 3.5 inch tft touch screen SPI Manufacturers, Suppliers, Factory

Are you facing a black screen on your LCD display? This problem can be frustrating, and it can be challenging to identify the root cause and resolve it. In this article, we will discuss some common reasons for this problem and share some tips on how to fix it.

Shenzhen Hongjia Technology has launched a 3.0-inch IPS display for the handheld small game console market. It has a resolution of 320*480 high-definition and delicate, 4:3 structure, horizontal display, and ultra-narrow frame; it uses high-brightness and low-power LED lights, which are clearly readable in outdoor sunlight, and the brightness can reach 1000 lumens; it supports 16/18/24BIT RGB interface and 39PIN standard interface.

Shenzhen Hongjia Technology specializes in the research and development, production and sales of 1.14-inch to 12.1-inch displays and supporting touch screens. We have a 3,000-square-meter clean room, three fully automatic production lines, and 12 years of industry experience. We have a team of experienced engineers who can provide advice to customers when designing products, thereby simplifying the design of the motherboard PWM. We have displays of various sizes that all support PWM dimming. Customers are welcome to email us for inquiries.

Completely eliminating LCD light leakage is difficult (especially against a pure black background, where slight light leakage may occur at the edges). However, through optimized design (such as high-precision shading structures and zoned light control), the use of high-quality materials (such as low-defect light guide plates and high-light-shielding adhesive strips), and rigorous production processes (such as full lamination and precision assembly), light leakage can be significantly reduced. Shenzhen Hongjia Technology has 12 years of industry experience, specializing in the research and development, production and sales of 1.14-inch to 12.1-inch LCD screens and matching touch screens. It has rich experience in dealing with backlight leakage and can meet the demanding requirements of our customers. We can also accept customization. Customers are welcome to email us for consultation.

Shenzhen Hongjia Technology mass-produces 3.92-inch square LCD screens with a resolution of 320*320, full-view IPS technology, and uses ILI9488 and ST7796 driver ICs. It supports SPI/MCU interfaces, as well as RGB and MIPI interfaces, making it suitable for customers using microcontrollers. This can significantly reduce overall product costs and enhance market competitiveness. Capacitive touchscreens can be shipped with the screen laminated.

In the design of small and medium-sized LCD panels, hardware engineers often encounter difficulties in understanding the differences between VCC, VDD, and IOVCC
