Description

Technical Field

[0001] The present invention relates to the field of display touch technology, and in particular to a display touch integrated module and a processing method thereof. Background Art

[0002] Touch modules are an important electronic component that is widely used in various electronic products, such as smart phones, tablet computers, laptops, smart home devices, etc. Due to the popularity of touch technology, touch modules have become an indispensable part of modern electronic products.

[0003] Touch modules are divided into Out-touch, On cell, In cell, etc. according to the technology. Out-touch is the most mature, but the structure is relatively thick. Oncell is to mount the touch panel on the outside of the display panel, which requires the panel factory to control the yield, and the module production process is relatively more. Incell is the simplest, that is, to embed the touch module into the display panel to integrate the touch panel and the display panel. However, Incell usually completes the embedding of the touch module before the display panel leaves the factory, which requires the process capability of the panel factory, and the cost of the driver IC of TDDI is also relatively high.
