China 3.01 inch Bar tft touch screen 170*560 Manufacturers, Suppliers, Factory

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.

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.

Shenzhen Hongjia Technology specializes in the research and development, production and sales of 1.14-inch to 10.1-inch display screens and matching touch screens. There are many standard models and customization is accepted. The touch screens produced by our company have high reliability, good anti-static performance, anti-fingerprint, anti-scratch, high surface hardness and many other advantages. They are widely used in medical, military, instrumentation and other products. Customers with needs are welcome to email us for consultation.

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.

Everyone knows that the working temperature of conventional TFT LCD screen is -20 to 70 degrees, the storage temperature is -30 to 80 degrees, and the working temperature of wide temperature TFT LCD screen is -30 to 85 degrees. In order to pursue a wider working temperature, some customers will test whether TFT LCD screen can work normally under extreme temperature. Many customers find that the words displayed on the LCD screen become very light when the temperature is very low, and the words become very dark when the temperature is very high. What's going on?

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.
