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...
