Description

Technical Field

[0001] The utility model relates to display technology, in particular to an ONCELL panel and a display module. Background Art

[0002] ONCELL panel, also known as On-Cell panel, is a touch screen technology that embeds the touch screen between the color film substrate and the upper polarizer of the display panel, that is, a touch sensor is configured on the liquid crystal panel. Compared with the external touch screen, this method has greatly improved product thickness and light transmittance, and is less technically difficult than the In-Cell technology.

[0003] After the touch sensor is manufactured on the surface of the color film substrate of the ONCELL panel, it needs to go through multiple cleaning, storage and transportation processes before the polarizer is attached. During these cleaning, storage and transportation processes, the touch sensor will inevitably come into contact with foreign objects and is easily scratched by foreign objects, resulting in poor touch.

The touch sensor 25 includes a transparent electrode layer 250, an insulating bridge layer 251 and a bridge layer 252 arranged on the color film substrate 24 in sequence, the first touch electrode 25a and the second touch electrode 252 are formed in the transparent electrode layer 250, the first touch electrode 25a is composed of a plurality of first electrodes, each of which is sequentially connected along the first direction, the second touch electrode 25b is composed of a plurality of second electrodes, each of which is sequentially disconnected along the second direction; the insulating bridge layer 251 is arranged on the first touch electrode 25a and corresponds to the disconnected portion of the second electrode, the bridge layer 252 is arranged on the insulating bridge layer 251, and sequentially connects each of the disconnected second electrodes.

[0033] Preferably, the first direction is perpendicular to the second direction.
