china tft lcd tn factory
The 7 inch tft lcd panel is a vertical screen design with a resolution of 800*1280,with MIPI interface.We can provide the driver board to use with HDMI and USB interface. It realizes the drive-free function, plug and play. At present, it is mainly used in medical electronics, face recognition and other fields.
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;
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.
