Problems solved by technology

The inventors of this case found that the touch pattern design on the touch display panel is precisely because the strip electrode area and the spacer area in the existing layout design match themselves in terms of shape factors such as width and spacing or do not match each other. The texture is obvious, thus affecting the visual effect

Abstract

The invention provides a touch display panel capable of improving the visual effect. The touch display panel comprises at least one strip-shaped electrode region and at least one spacing region, which are arranged alternatively, wherein each strip-shaped electrode region comprises a plurality of strip-shaped signal lines distributed side by side, each spacing region comprises a plurality of spacers distributed side by side, each signal line and each spacer are the same in width, and a distance between each two adjacent signal lines in each strip-shaped electrode region is equal to a distance between each two adjacent spacers in each spacing region and is integer multiples of a distance among sub pixel units on the touch display panel. Accordingly, the invention also provides a touch display device provided with the touch display panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to the layout design of touch patterns in a touch display panel, and a touch display device with the touch display panel. Background technique [0002] At present, the touch display panel has become the mainstream mobile display terminal configuration, and among them, the capacitive touch screen has an absolute advantage. Among various capacitive touch screens, a touch screen using a hybrid touch technology (hybrid in cell) has a very good prospect because of its good signal-to-noise ratio and compatibility with on-cell technology. Generally, in an existing touch screen using a hybrid in cell technology, the Tx electrodes are integrated in the liquid crystal cell, and the Rx electrodes are arranged outside the liquid crystal cell in the form of an ITO sensor. Specifically, the layout design of the Rx electrodes usually includes two parts: one part is a strip electrode (pro...
