Embodiment Construction

[0062] As described in the background technology, the material of the touch sensing electrode in the prior art usually selects ITO, but the impedance of ITO is relatively large, so the noise is relatively large, which affects the sensitivity of touch sensing; and the production process of the touch sensing electrode of the metal grid More complex, higher cost, lower yield.

[0063] In order to solve the above-mentioned technical problems, the present invention provides a method for manufacturing a color filter, in which a plurality of first metal grid electrodes and second metal grid electrodes for mutual capacitance touch detection are directly formed on the substrate. A black matrix and a color photoresist for color filtering are formed above the first metal grid electrode and the second metal grid electrode. In the manufacturing method of the present invention, the electrodes used for touch detection are well compatible with the existing color filter manufacturing technolog...

Abstract

The invention provides the manufacture method of a color filter, the color filter and a liquid crystal display device. The manufacture method of the color filter comprises the steps that a first metal grid layer is formed on a substrate, wherein the first metal grid layer comprises a number of first metal grid electrodes; the first metal grid layer is covered by an insulating layer; a groove is formed in the insulating layer; and a second metal grid layer is formed in the groove, wherein the second metal grid layer comprises a number of second metal grid electrodes. The second metal grid electrodes and the first metal grid electrodes are used to form mutual capacitance used for touch detection. The first metal grid electrodes and the second metal grid electrodes are made of metal, and have lower impedance compared with a touch detection electrode of an ITO material. The noise of touch detection is reduced. The sensitivity of touch monitoring is improved. Compared with the existing color filter manufacture technology, the color filter manufacture method provided by the invention has the advantages of great compatibility, high yield of manufactured color filter and reduced color filter cost.

Description

technical field [0001] The invention relates to the display field, in particular to a manufacturing method of a color filter, a color filter and a liquid crystal display device. Background technique [0002] Liquid crystal display devices are widely used in various fields due to their small size, light weight, and low radiation. [0003] A liquid crystal display panel is the most important component of a liquid crystal display device. The liquid crystal display panel includes an array substrate (ie, a TFT substrate), a color filter (CF substrate) opposite to the array substrate, and liquid crystals filled between the array substrate and the color filter. Wherein, the electrodes on the array substrate and the color filter control the deflection of liquid crystal molecules to adjust the passing rate of external light, thereby achieving the purpose of display. [0004] refer to figure 1 , shows a schematic cross-sectional view of a color filter in the prior art, the color fi...
