Problems solved by technology

However, the electrode patterns of the touch electrode layer (such as metal mesh electrodes) and the light-shielding structure of the display panel are prone to produce moiré in the line of sight, resulting in a decrease in the display quality of the touch display device.

Embodiment Construction

[0061] As used herein, "about," "approximately," "essentially," or "essentially" includes the stated value and the average within an acceptable range of deviation from the particular value as determined by one of ordinary skill in the art, taking into account the The measurement in question and the specific amount of error associated with the measurement (ie, limitations of the measurement system). For example, "about" can mean within one or more standard deviations of the stated value, or for example within ±30%, ±20%, ±15%, ±10%, ±5%. Furthermore, "about", "approximately", "essentially" or "substantially" used herein may select a more acceptable range of deviation or standard deviation according to measurement properties, cutting properties or other properties, and may not use One standard deviation applies to all properties.

[0062] In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. It will be understood that when an elem...

Abstract

The invention provides a touch display device. The touch display device comprises a display panel and a plurality of touch electrodes. The touch electrodes are arranged on the display panel in an overlapping mode and are provided with a plurality of wire sections which intersect with one another. The first distance SP1 between any two adjacent wire segments arranged along the first direction in the wire segments satisfies the following relational expression: PPI is the number of pixels per inch of the display panel, B is 1.8 or 2.1, and N is 1 or a positive even number.

Description

technical field [0001] The present invention relates to a display device, in particular to a touch display device. Background technique [0002] In recent years, people's dependence on electronic products is increasing day by day. In order to achieve more convenience, smaller volume, and more user-friendly, the input devices of many information products have changed from traditional keyboards or mice to touch panels, and display panels with touch functions have become the standard for mobile devices today. equipped. Due to the advantages of fast response, good reliability and high durability, capacitive touch technology has become the mainstream of touch technology and is widely used in related electronic products (such as mobile phones, tablet computers or smart watches). According to the integration method of touch technology and display panel, capacitive touch display devices can be roughly divided into three types: out-cell, on-cell and in-cell. . [0003] Generally ...
