Embodiment Construction

[0036] In order to reduce the width of the side frame of the touch display device and meet the user's requirement for a narrow frame of the touch display device, an embodiment of the present invention provides a touch display screen and a touch display device. In the technical solution of the present invention, each first electrode trace is directly led out from the side of the display area close to the FPC, and does not occupy the width of the side frame. Therefore, the side frame of the touch display device can be designed to be narrow, which greatly satisfies the It satisfies the user's demand for a narrow frame of the touch display device. In order to make the purpose, technical solution and advantages of the present invention clearer, the following examples are given to further describe the present invention in detail.

[0037] Such as image 3 As shown, the touch display screen provided by the embodiment of the present invention includes:

[0038] A plurality of first ...

Abstract

The invention discloses a touch display screen and a touch display device. The width of a side frame of the touch display device is reduced, and the narrow frame requirements of users for the touch display device are met. The touch display screen comprises a plurality of horizontally arranged first electrode wires, a flexible printed circuit (FPC) located above or below a display area and first electrode routing wires in corresponding conductive connection with the first electrode wires. Every first electrode routing wire is led out of one side of the display area close to the FPC and is in conductive connection with the FPC. According to the technical scheme, every first electrode routing wire is directly led out of one side of the display area close to the FPC and does not occupy the width of the side frame, so that the side frame of the touch display device can be designed to be narrow, and the narrow frame requirements of the users for the touch display device are greatly met.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch display screen and a touch display device. Background technique [0002] As an input medium, the touch screen provides users with better convenience than the keyboard and mouse. Among all kinds of touch screens, the mutual capacitive touch screen is favored by more and more consumers due to its high sensitivity and advantages of multi-touch true touch. [0003] The mutual capacitive touch display screen includes a set of drive electrode lines and a set of detection electrode lines that cross each other and are insulated. When there are n (n refers to a natural number above 1) drive electrode lines and m (m refers to a natural number above 1) ) detection electrode wires, m+n electrode wires are required to be conductively connected to a flexible printed circuit board (Flexible Printed circuit, FPC for short). The basic principle is: apply voltage to the dri...
