[0034] figure 2 It is a schematic structural diagram of a touch panel according to an embodiment of the present invention. The touch panel includes a first substrate and a second substrate, and touch electrodes are arranged on the first substrate 10 . From figure 2 It can be seen from the figure that the touch electrodes include block electrodes 11 arranged in a matrix, and strip electrodes 12 are arranged between two adjacent rows of block electrodes 11 to reduce the interference of surrounding circuits on the block electrode signals.

[0035] In practical applications, the bulk electrodes 11 of the touch electrodes are all connected to the integrated circuit 21 of the touch display panel, and the bulk electrodes 11 are also used as common electrodes for display. Due to the different distances between the block electrodes 11 and the surrounding circuits, the signals of the block electrodes 11 are interfered differently by the surrounding circuits, resulting in large diffe...

Abstract

The invention discloses a touch panel and a display device. The touch panel comprises a first substrate and a second substrate arranged in opposite manner. The first substrate is provided with a touchelectrode that includes block electrodes arranged in matrix manner; between every two adjacent rows of block electrodes or two adjacent block electrodes, a strip electrode for reducing disturbance ofa surrounding circuit upon block electrode signals is provided. In the touch panel, the strip electrode for reducing the disturbance of the surrounding circuit upon the block electrode signals is arranged between every two adjacent rows of block electrodes or two adjacent block electrodes, each block electrode is adjacent to the corresponding strip electrode, the strip electrodes can shield and protect the block electrodes, the disturbance of the surrounding circuit upon the block electrodes is relieved, and signal differences between the block electrodes are decreased, and touch anomaly andpoor displaying are avoided. The invention also discloses a display device comprising the touch panel.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch panel and a display device. Background technique [0002] Touch screens, also known as touch panels, have been widely used in various electronic products and widely accepted by consumers. Therefore, the industry has been devoting itself to improving touch screen display technologies to bring better user experience to consumers. [0003] Multi-touch is a technology implemented jointly by human-computer interaction technology and hardware devices, and can perform human-computer interaction operations on computers without traditional input devices. However, as the display and touch integration of small-sized display panels is getting higher and higher, and the performance requirements are becoming more and more stringent, a fully embedded (Full In-Cell, FIC) touch panel appears, which integrates the touch function in the Inside the panel, the touch electrodes ...
