Touch panel repair circuit

Abstract

The invention provides a touch panel repair circuit. The repair circuit comprises a connecting wire, a data wire, a read wire, a data wire repair wire, a read wire repair wire, a data wire operational amplifier, and a read wire operational amplifier, wherein the data wire is electrically connected with a plurality of display units; one end of the data wire is transversely arranged on the connecting wire in an insulated way; the read wire is electrically connected with a plurality of touch units; one end of the read wire is transversely arranged on the connecting wire in the insulated way; one end of the data wire repair wire is arranged above or under the connecting wire in the insulated way, while the other end is transversely arranged on the other end of the data wire and the read wire in the insulated way; the read wire repair wire is insulated from the data wire repair wire; one end of the read wire repair wire is arranged above or under the connecting wire in the insulated way, while the other end is arranged above or under the data wire repair wire in the insulated way; the data wire operational amplifier is arranged on the data wire repair wire; and the read wire operational amplifier is arranged on the read wire repair wire and opposite to the data wire operational amplifier. The touch panel repair circuit is used for repair of the data wire and the read wire, does not need increase space occupied by the original repair wire, and keeps the same panel design.

Description

technical field [0001] The invention relates to a panel repair circuit, in particular to a touch panel repair circuit. Background technique [0002] In recent years, the touch display screen led by the product released by Apple Inc. - I-Phone has caused a whirlwind of touch control. Whether it is a mobile phone, a desktop monitor, a notebook computer, or even a home TV set, everyone hopes to have a touch screen display. Features. The current touch control method is generally a touch control method of an external display, that is, a panel or a film with a touch function is attached to a liquid crystal display. These technologies include capacitive, resistive, acousto-optic and so on. At present, in order to reduce costs, panel manufacturers are focusing on integrating the touch function into the LCD itself. In order to achieve this goal, it is necessary to process the thin film transistor or color filter into a touch sensor, which can make the touch electrode change electri...

AI Technical Summary

Problems solved by technology

However, in the touch panel, because the pixel has an additional touch unit, it uses an independent read signal line, and the signal transmission direction of the read signal line is opposite to that of the data line used by the thin film transistor, so there is no relevant The repair line design of the read signal line, if the read signal line breaks, it cannot be repaired
