Generally, a single bonding material is used for bonding during the stacking process. When the LCD monitor is lit by the backlight, it may see uneven color frames or color patches on the display panel. This color frame or color block is yellow on its white display panel and white on its gray display panel. This phenomenon is called color ura (Mura). Such a Mura is a visual defect commonly found in electronic products like liquid crystal displays, which usually causes low contrast, non-uniform brightness areas, edge blurring, etc., usually in the range of more than one picture element, which will be brought to the observer. To visual discomfort. Generally, in an electronic product similar to such a liquid crystal display, it basically has an upper glass substrate, a lower glass substrate, and a liquid crystal layer. The above-mentioned Mura phenomenon is caused by a certain difference in thickness between the upper glass substrate and the lower glass substrate in the liquid crystal display structure. After the liquid crystal is injected between the two glass substrates and after the frame is sealed, the inside of the liquid crystal display is stressed. , resulting in uneven liquid crystal thickness. When this stress reaches a certain level, 'Mura 4 M394529 phenomenon may occur. Therefore, not only the Mura phenomenon may occur in the liquid crystal display itself, but also the touch panel attached to the liquid crystal display may have a certain thickness difference.
