Technical Q&A
Q: What are the main reasons for the water ripple on the air-bonded screen module?
A: The phenomenon of water ripples is also related to the structural design and the panel material of the display itself. The following is mainly analyzed from two aspects: 1)Structural: No matter TN panel or IPS panel, as long as the surface touch screen is pressed in the design of the structure, the backlight part of the back display screen is pressed by the external force of the casing to cause deformation, which will cause water ripple. Therefore, when designing the structure, it is necessary to avoid the backlight part of the display screen as much as possible, so that it is not squeezed by external force, or it is forced to be evenly distributed over the entire surface; 2)Panel material: If the capacitive screen module adopts the display withTN panel, the strength of the tempered glass(cover lens) should be sufficient, otherwise the surface pressing will cause water ripple when the deformation contacts the glass of the display panel; If it is the IPS panel display, only the backlight part on the back of the display screen should not be locally squeezed by external force and no water ripple will occur;
Q: What are the reasons for the air-bonded capacitive screen module to generate Newton's rings? How to solve the problem?
A: The reason for air bonding screen module generating Newton's ring is that the surface of capacitive touch screen and the LCD screen are not parallel enough, and the issue is generally caused by the collapse when the capacitive touch screen being pressed. To improve this situation what we need do is: first, increase the TP intensity second, increase the gap between TP and LCM. Third: to use anti-Newton ring polarizer or the anti-Newton ring TP
