First of all, the advantage of incell LCD screens is that they are thinner and lighter than traditional TFT displays because they integrate the touch sensor and display layer into a single layer. Traditional TFT LCD screens require external mounting to fit the touch screen, which increases the thickness. In addition, the touch screen also requires a separate design of a cable, which will occupy the space inside the machine. Incell LCD screens only need to be attached to a layer of glass cover to form a complete LCD touch screen assembly, which makes them ideal for portable devices such as smartphones and tablets. The reduction in thickness and weight makes the design more compact and stylish, which is very important for the trend of thinner and more portable devices.

In order to meet the increasing number of new orders, Shenzhen Hongjia Technology added a fully automatic TFT screen production equipment to the factory on November 25, 2024, including one-stop feeding such as glass cleaning, COG bonding, FOG bonding, backlight assembly, etc. before production.

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.

LCD screen leakage typically refers to the leakage of liquid/gel-like substances such as liquid crystal material or sealant from within the screen due to external forces or inherent material defects. Common symptoms include abnormal patches (such as black spots, white spots, or lines) or localized malfunctions in the display area. Lightly pressing the edge of the screen can cause a sensation of liquid flowing, which is common in LCD (liquid crystal display) screens
