Embodiment Construction

[0029] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for ease of description, the drawings only show a part but not all of the content related to the present invention.

[0030] The existing in-cell touch panel (In-Cell TP) technology integrates driving electrodes and sensing electrodes with touch functions on the side of the color film substrate through a touch graphic design to form a touch screen. In actual production, the driving electrode and the sensing electrode can be arranged on the same conductive layer or on two different conductive layers of the color filter substrate. Compared with the color film substrate without the touch function, the conductive layer added to realize the touch function is easily affected or d...

Abstract

The invention discloses a touch screen display panel and a touch screen display device. The touch screen display panel comprises a plurality of drive electrodes, a plurality of induction electrodes insulated from the drive electrodes, a plurality of drive electrode leads, a plurality of induction electrode leads, a plurality of first external terminals and a plurality of second external terminals. The drive electrodes, the induction electrodes, the drive electrode leads, the induction electrode leads, the first external terminals and the second external terminals are arranged on a color film substrate, wherein the drive electrodes are connected with the first external terminals through the drive electrode leads, and the induction electrodes are connected with the second external terminals through the induction electrode leads. The touch screen display panel further comprises a plurality of third external terminals, a plurality of fourth external terminals, a common electrode line and a static protection unit, wherein the third external terminals and the first external terminals are correspondingly arranged and electrically connected, the fourth external terminals and the second external terminals are correspondingly arranged and electrically connected, the third external terminals, the fourth external terminals, the common electrode line and the static protection unit are arranged on a TFT array substrate, and the third external terminals and the fourth external terminals are connected with the common electrode line through the static protection unit. By the adoption of the touch screen display panel and the touch screen display device, static protection of the drive electrodes and the induction electrodes can be achieved.

Description

Technical field [0001] The present invention relates to the field of display technology, and in particular to a touch screen display panel and a touch screen display device. Background technique [0002] Electrostatic Discharge (ESD for short) will quickly occur with extremely high intensity, breakdown semiconductor devices, or generate enough heat to melt semiconductor devices. This hazard usually causes some components to be degraded or scrapped without being easily noticed. , Bring great economic losses. Therefore, electrostatic discharge can bring fatal harm to electronic products. It not only reduces the reliability of the product, but also increases the maintenance cost. The damage caused by electrostatic discharge every year brings a cost of billions of dollars to the world's electronic manufacturing industry. Summary of the invention [0003] The embodiments of the present invention provide a touch screen display panel and a touch screen display device, which solve the t...
