Abstract

The invention provides a touch display panel and a touch display device. The transmittance of an optical filtering unit corresponding to any subpixel in a first column of subpixels of the touch display panel is smaller than that of optical filtering units corresponding to subpixels of the same row in the nth column of subpixels in the row direction; in addition, the first column of subpixels are positioned at one side, where the friction direction of touch electrodes in an alignment layer is in the row direction, of the bias direction, namely a clearance is formed between every two adjacent touch electrodes in the row direction; the transmittance of the optical filtering unit corresponding to the subpixel close to one side of the clearance is smaller than that of the optical filtering unit corresponding to the subpixel at the other side in the same row; the optical filtering unit with low transmittance is positioned at one side, where the friction direction of the clearance in the alignment layer is in the row direction, of the bias direction. When the optical filtering unit with low transmittance corresponds to the friction alignment layer, a friction abnormal area is generated at the clearance, so that the visibility of the clearance is reduced when a frame is displayed, and the display effect is improved.

Description

technical field [0001] The present invention relates to the technical field of touch display, and more specifically, to a touch display panel and a touch display device. Background technique [0002] With the rapid development of display technology, touch display panels have been accepted and widely used by people, such as smart phones, tablet computers and other electronic devices that use touch display panels. Today's touch display panels include an In-Cell touch display panel in which the touch structure is fabricated in the display panel, which has the advantages of low cost, small thickness, and narrow frame, and has become the main development of today's touch technology. direction. However, the display effect of the touch display device including the existing touch display panel needs to be improved. Contents of the invention [0003] In view of this, the present invention provides a touch display panel and a touch display device, which optimizes the structure of ...
