Embodiment Construction

[0067] figure 1 It is a schematic diagram of the touch display panel 1 of the present invention. The touch display panel 1 includes a display panel 10 , a touch layer 50 , a first polarizing film 60 , a second polarizing film 70 and a protection layer 80 .

[0068] The display panel 10 includes a first substrate 11 , a display medium layer 12 , a color filter layer 13 , a second substrate 14 , and a thin film transistor layer 15 . The first substrate 11 can be made of transparent material, such as glass. The thin film transistor layer 15 is disposed on the first substrate 11 . The display medium layer 12 is disposed on the thin film transistor layer 15 or between the first substrate 11 and the second substrate 14 . The display medium layer 12 can be a liquid crystal display layer or an organic light emitting display layer. In this embodiment, the display medium layer 12 is a liquid crystal layer, and the liquid crystal layer includes liquid crystal molecules 121 and is dis...

Abstract

The invention discloses a touch display panel. The touch display panel comprises a display panel and a touch layer. The display panel comprises a plurality of pixel regions. The touch layer is dispose don the display panel, and comprises a plurality of lead regions and a plurality of slits. Each pixel region has a pixel width, and the corresponding adjacent lead region and the corresponding adjacent slit has specified widths. The moire rate is defined as (the specified width / the pixel width)*100%. When the moire rate meets a scope of the following formula, the moire effect of the touch display panel can be reduced. The formula is 25%+(50%*N)-a%<=the moire rate<=25%+(50%*N)+a%, wherein the N is 0 or a positive integer, the a is an adjustment value, and the a is between 0 and 20.

Description

technical field [0001] The present invention relates to a display panel, in particular to a touch display panel. Background technique [0002] Nowadays, various electronic devices such as mobile phones or tablet computers have widely used touch screens as input interfaces. Generally speaking, the touch screen includes a display panel, a touch layer and a color filter disposed on the display panel. The touch layer includes a plurality of transparent electrodes arranged in an array for detecting coordinates of touch. A color filter also includes pixels arranged in an array to form an image. [0003] The existing transparent electrodes are stacked on the pixels. When the light passes through the color filter and the transparent electrode, due to the arrangement of the existing transparent electrodes and pixels, there will be obvious moire effect (moire pattern) in some display screens, which will affect the image quality of the display screen. .
