Abstract

The invention discloses a self-contained embedded touch panel and a detection method. The method comprises the following steps of grouping touch electrodes on a touch panel into a first touch electrode and a second touch electrode which are alternatively arranged; penetrating pictures of the same gray scale into first signal leading-in ends of the first touch electrode and the second touch electrode, and penetrating corresponding public electrode signals into second signal leading-in ends of the first touch electrode and the second touch electrode so as to judge whether the touch electrodes are normal, wherein when penetrating the pictures of the same gray scale, driving signals with alternative positive and negative polarities are adopted. According to the self-contained embedded touch panel and the detection method, the normal state, the short-circuit condition and the breaker status for connection of the touch electrodes can be detected, so that non-performing products are intercepted to prevent resource waste caused after inflowing the non-performing products, and thus the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display control, in particular to a self-contained embedded touch panel and a detection method. Background technique [0002] With the popularity of smart electronic products, capacitive touch screens are widely used in various electronic products such as smart phones and tablet computers. Existing capacitive touch screen structures include external capacitive screens represented by G+G, G+F, GFF, OGS, etc., and embedded capacitive screens represented by Oncell and Incell. [0003] In recent years, people have pursued an increasingly thinner and lighter user experience, leading to a situation where OGS, Oncell, and Incell technologies compete with each other. Among them, due to the unique advantages of Incell technology in the manufacturing process, it can be lighter and thinner than OGS and Oncell, and has better light transmission, and can better meet customer needs, and it is bound to b...
