Abstract

The invention discloses a colored film substrate and a touch screen display device. The colored film substrate comprises a black matrix, color resistors, a plurality of driving electrodes and a plurality of induction electrodes, wherein the color resistors distributed in an array manner are formed within an opening of the black matrix, distance between the driving electrodes and the induction electrodes is [nL-D, nL+D], wherein the n is a positive integer, the L is the length of the color resistor, and the D is the width of the black matrix. The driving electrodes and the induction electrodes function in electrostatic protection, and yield of the touch screen display device is increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a color filter substrate and a touch screen display device. Background technique [0002] Electrostatic Discharge (ESD for short) will occur rapidly with extremely high intensity, break down semiconductor devices, or generate enough heat to melt semiconductor devices. This hazard usually causes some components to be degraded or scrapped when it is not easy to detect. , causing huge economic losses. Therefore, electrostatic discharge will bring fatal harm to electronic products, which not only reduces the reliability of products, but also increases maintenance costs. Damage caused by electrostatic discharge costs the world's electronics manufacturing industry billions of dollars annually. [0003] The existing In-Cell Touch Panel (In-Cell TP) technology integrates the driving electrodes and sensing electrodes with touch function on the side of the color filter substrate through...
