Problems solved by technology

[0004] However, with the development of the technology level and the continuous improvement of user experience requirements, the disadvantages of this touch-type liquid crystal display panel are becoming more and more prominent: due to the large thickness of the additional touch panel, the touch-type liquid crystal panel The performance of the screen is relatively poor in terms of light transmission and portability
In addition, due to the poor light transmittance of the screen, it is necessary to increase the power consumption in order to achieve a higher screen brightness of the touch-type liquid crystal display panel.
The above shortcomings all reduce the performance of traditional touch-type liquid crystal display products

Embodiment 1

[0037] Such as figure 2 As shown, the color filter substrate provided in this embodiment includes:

[0038] A substrate 1, a black matrix 2 and a color pixel unit 3 are arranged on the lower surface of the substrate 1, a driving electrode 4 is arranged on the black matrix 2 and the color pixel unit 3, a passivation layer 8 is arranged on the driving electrode 4, the passivation layer 8 A common electrode (not shown in the figure) is also arranged on the top;

[0039] A polarizer 6 is arranged on the upper surface of the substrate 1, a sensing electrode 5 is arranged between the substrate 1 and the polarizer 6, and a passivation layer 7 is also arranged between the sensing electrode 5 and the polarizer 6; in this embodiment, the The sensing electrodes 5 are arranged under the polarizer 6, so that the polarizer 6 can mechanically protect the sensing electrodes 5, effectively preventing the sensing electrodes from being damaged due to frequent touches by the user, but the prese...

Embodiment 2

[0052] Such as Figure 7 As shown, the difference between this embodiment and the first embodiment lies in that the driving electrodes 4 are disposed on the substrate 1 , and the black matrix 2 and the color pixel units 3 are disposed on the driving electrodes 4 . In this case, the surface of the substrate 1 on which the driving electrodes 4 are formed is flat, which can prevent the driving electrodes 4 from forming gaps. Therefore, in this embodiment, the driving electrodes 4 do not include metal electrode parts. Certainly, in this embodiment, the driving electrodes may still include the transparent electrode part 41 and the metal electrode part 42 as in the first embodiment, which is not limited in the present invention. Other structures of the color filter substrate in this embodiment are the same as those of the color filter substrate in Embodiment 1, and will not be repeated here.

Embodiment 3

[0054] Such as Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that a polarizer 6 is arranged on the upper surface of the substrate 1, the sensing electrode 5 is arranged on the polarizer 6, and the surface of the sensing electrode 5 is provided with a passivation layer. 10. Other structures are the same as those of the color filter substrate in Embodiment 1, and will not be repeated here.

Abstract

Aiming at improving the performance of touch control LCD (Liquid Crystal Display) panels, the invention discloses a color film substrate and a manufacturing method thereof and a touch control LCD panel. The color film substrate comprises a substrate; a driving electrode is arranged on the lower surface of the substrate; an induction electrode is arranged on the upper surface of the substrate; and the driving electrode and the induction electrode take the substrate as a dielectric layer to form a touch control inductive capacitor. The color film substrate and the manufacturing method can be used in the technical field of touch control of liquid crystal display.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a color filter substrate, a manufacturing method thereof, and a touch-sensitive liquid crystal display panel. Background technique [0002] The touch-type liquid crystal display panel develops rapidly, and has gradually developed into a mainstream flat panel display panel. With the continuous improvement of optical characteristics, electrical characteristics and thinning degree required by consumers for display panels, designing and manufacturing high-performance, low-cost, ultra-thin touch-sensitive liquid crystal display panels has gradually become the main task of major related companies. Target. [0003] Such as figure 1 As shown, most of the mainstream products of the current touch-type liquid crystal display panel adopt the structural design of adding a touch panel 02 on the traditional liquid crystal panel 01, that is, use an adhesive 03 to fix a touch pan...
