Abstract
The present invention provides a touch display panel, which includes an opposite substrate and an array substrate, the opposite substrate includes a first base substrate, and a high-resistance film material layer arranged on the first base substrate , the square resistance of the high-resistance film material layer is greater than or equal to 107Ω / □ and less than or equal to 1012Ω / □. By using the above-mentioned type of high-resistance film material layer, when static electricity is generated, the charge generated by high voltage (such as above KV level) can be used as a charge discharge path through the high-resistance film material layer to play the role of static discharge; and When touch detection is performed, the high-resistance film material layer will not release the charges accumulated due to touches such as fingers, and the shielding of charge signals generated by touches such as fingers is weak, and will not affect the touch performance of the touch display panel. influences.
Description
technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a touch display panel. Background technique [0002] In the field of liquid crystal display technology, figure 1 It is a schematic diagram of the structure of the display panel in the prior art Figure 1 ,like figure 1 As shown, the existing display panels include two upper and lower substrates, that is, the array substrate 11 and the color filter substrate 12. In addition, in order to prevent the influence of the external electric field on the display, a shielding film is usually coated on the outside of the color filter substrate 12. For example, indium tin oxide (Indium-Tin-Oxide, hereinafter referred to as: ITO) film 13, wherein the thickness of the ITO film 13 is about [0003] In addition, after the display panel is assembled, the above-mentioned ITO film 13 can be electrically connected to the ground block 15 on the array substrate through the c...
