Problems solved by technology

However, such an assembly method will result in a large amount of gaps between the touch panel 102 and the liquid crystal panel 104, which may easily cause light leakage and reduce the light transmittance.
Therefore, if figure 2 The design of another conventional liquid crystal display device 200 shown is to use an optical adhesive 206 to bond the touch panel 202 and the liquid crystal panel 204 in a full-surface adhesive manner to solve the problem of light leakage. However, using the optical adhesive 206 to bond The reliability of the method is not high and it is easy to generate air bubbles
Furthermore, if figure 1 and figure 2 The conventional designs shown all have the problem of too many components, which makes it difficult to reduce the thickness of the overall structure after assembly

Embodiment Construction

[0045] The aforementioned and other technical contents, features and functions of the present invention will be clearly presented in the following detailed description of the embodiments with reference to the drawings. The directional terms mentioned in the following embodiments, such as: up, down, left, right, front or back, etc., are only directions referring to the attached drawings. Accordingly, the directional terms are used to illustrate and not to limit the invention.

[0046] image 3 It is a schematic diagram showing a color filter 10 with touch function according to an embodiment of the present invention. Such as image 3 As shown, a first semi-penetrating conductive layer 14 , a gap layer 16 and a second semi-penetrating conductive layer 18 are sequentially deposited on the transparent substrate 12 . The semi-penetrating conductive layers 14, 18 and the gap layer 16 can be formed on the transparent substrate 12 by vacuum coating methods such as evaporation or spu...

Abstract

The invention relates to a colorful filter with touch function, comprising: a transparent substrate, a conductive layer, a filter layer and a protective layer, wherein the conductive layer is formed on the transparent substrate to sense a touch signal and provided with boundary electrodes on the periphery thereof, the filter layer is formed on the conductive layer, and the protective layer is formed on the filter layer. The filter layer comprises a plurality of red light penetrating zones, green light penetrating zones and blue light penetrating zones, and a pixel unit of a liquid crystal display device at least covers one red light penetrating zone, a green light penetrating zone and a blue light penetrating zone respectively.

Description

technical field [0001] The invention relates to a color filter with touch function and a liquid crystal display device including the color filter. Background technique [0002] figure 1 It is a schematic diagram of a conventional liquid crystal display device 100 with touch function. Such as figure 1 As shown, the liquid crystal display device 100 includes a touch panel 102 and a liquid crystal panel 104 , and the touch panel 102 is pasted on the liquid crystal panel 104 by a double-sided adhesive 106 to combine them. However, this assembling method will result in a large amount of gaps between the touch panel 102 and the liquid crystal panel 104 , and such gaps will easily cause light leakage and reduce the light transmittance. Therefore, if figure 2 The design of another conventional liquid crystal display device 200 shown is to use an optical adhesive 206 to bond the touch panel 202 and the liquid crystal panel 204 in a full-surface adhesive manner to solve the probl...
