Color filter substrate and display device

Abstract

An embodiment of the invention discloses a color filter substrate and a display device. The color filter substrate comprises a touch sensing component, touch sensing units and a lead wire unit, wherein the touch sensing component is arranged on a black matrix layer; each touch sensing unit comprises a driving electrode wire, a sensing electrode wire as well as a driving electrode and a sensing electrode arranged between the driving electrode wire and the sensing electrode wire; the driving electrode and the sensing electrode are arranged on the same layer and mutually insulated, the driving electrode leads out of the driving electrode wire, and the sensing electrode leads out of the sensing electrode wire; the lead wire unit comprises at least two driving electrode lead wires and one sensing electrode lead wire, and each driving electrode lead wire is in corresponding connection with the driving electrode wire in each touch sensing unit. According to the color filter substrate and the display device, touch and display are integrated, the process and the structure are simplified, and the transmittance and the display effect of a display are improved; mutual capacitance multi-point touch is realized on a single layer, so that the cost is reduced, and the yield is improved.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a color filter substrate and a display device. 【Background technique】 [0002] Such as figure 1 As shown, the touch function of a traditional liquid crystal display (LCD, Liquid Crystal Display) is realized by adding a capacitive touch screen on the liquid crystal screen of the liquid crystal display. The LCD display electrode 8 and two pieces of conductive glass containing an alignment layer and liquid crystal form a liquid crystal cell 5, and then the upper polarizer 3 is pasted on the upper surface of the liquid crystal cell 5, and the lower polarizer 4 is bonded on the lower surface of the liquid crystal cell 5. into a conventional LCD display. Then the touch screen 1 is glued together with the upper surface of the liquid crystal display through the double-sided adhesive tape 2 . Its working process is: when the user clicks the touch screen, the click signal of the touc...

Problems solved by technology

[0004] Due to the addition of a touch screen, regardless of whether the material of the touch screen is glass or PET, the transmittance of the display will be reduced, and because the transmittance is affected, the display effect of the display will also be affected; moreover, the process and structure of the touch screen are complex, not only high cost and low reliability

If the structural design is unreasonable or the assembly is not good, Newton rings are likely to appear, and the click life is also limited. In addition, due to the large number of circuit structures, the probability of problems during processing and use is also relatively high.
