Embodiment 1

[0038] In this embodiment, the touch function of the liquid crystal display is realized by integrating the touch keys on the surface of the first substrate, specifically, as figure 2 , the liquid crystal display provided by this embodiment includes:

[0039] The first substrate 201 and the second substrate 202 are oppositely arranged, and one or more touch buttons 213 are located on the surface of the first substrate 201 away from the second substrate 202 .

[0040] Wherein, the touch key 213 specifically includes a transparent electrode disposed on the surface of the first substrate 201, and the transparent electrode has a transparent touch key pattern.

[0041] In addition, the transparent electrode is an indium tin oxide electrode, the indium oxide in the indium tin oxide electrode has high visible light transmittance and infrared light reflectivity, and tin oxide has strong electrical conductivity; and the indium oxide The tin oxide electrode can be combined with the sub...

Embodiment 2

[0051] Corresponding to the liquid crystal display provided in the above embodiments, this embodiment provides a method for manufacturing the liquid crystal display, in which one or more touch points are formed on the surface of the first substrate of the liquid crystal display on the side away from the second substrate The method of pressing the button to realize the touch function of the liquid crystal display, specifically, such as image 3 As shown, the method includes the following steps:

[0052] A first substrate and a second substrate are provided, and the first substrate and the second substrate are arranged oppositely.

[0053] In this embodiment, a glass substrate can preferably be selected as the first substrate and the second substrate. The glass substrate has the advantages of high dimensional accuracy, strong heat resistance, and low thermal expansion coefficient, but the present invention does not limit the first substrate and the second substrate. specific ty...

Abstract

The invention provides a liquid crystal display. The liquid crystal display comprises a first baseboard and a second baseboard which are oppositely arranged, and one or more touch keys positioned on the surface of one side (of the first baseboard) far away from the second baseboard. According to the liquid crystal display and a manufacturing method of the liquid crystal display, the touch function is realized by directly manufacturing the touch keys at the first baseboard of the liquid crystal display, a touch function module does not need to be adhered through a two-sided adhesive tape, i.e. no two-sided adhesive tape is demanded, and no baseboard needs to be separately provided for the touch function module, therefore, compared with the prior art, baseboards and two-sided adhesive tapes for separately manufacturing the touch function module are saved, then the manufacturing cost of the liquid crystal display provided by the invention is lower, and the liquid crystal display is lighter at the same time; and moreover the influence of the two-sided adhesive tape to the touch key is eliminated, so that the touch key of the liquid crystal display provided by the invention has higher sensitivity, higher precision and higher reliability compared with the prior art.

Description

technical field [0001] The invention relates to the technical field of displays, and more specifically, relates to a liquid crystal display with a touch function. Background technique [0002] With the rapid development of display technology, liquid crystal display with touch function has attracted more and more attention due to its advantages of convenient operation. [0003] The basic structure of a conventional liquid crystal display with touch function, such as figure 1 As shown, from top to bottom are: touch function module 101 , double-sided adhesive 102 , first polarizer 103 , first glass substrate 104 , liquid crystal layer 105 , second glass substrate 106 , and second polarizer 107 . [0004] Wherein, the touch function module 101 includes a touch layer disposed on one substrate or between two substrates, and the touch function module 101 is pasted on the outside of the liquid crystal display by a double-sided adhesive 102 . [0005] However, in the actual applica...
