Problems solved by technology

[0004] The defective that the above-mentioned scheme that realizes liquid crystal display handwriting input function exists is: handwriting input board can increase the thickness of liquid crystal display as an independent part, and the trend of thinning development of liquid crystal display does not conform to; The problem of unstable and insecure assembly leads to a decrease in input accuracy; for the electromagnetic induction handwriting input board, when it is assembled on the back of the liquid crystal display, due to the thickness of the liquid crystal panel and the backlight module between the electromagnetic induction pen , so it will affect the identification of electromagnetic signals and reduce the input accuracy

[0033] figure 1 It is a partial side view structure diagram of the electromagnetic induction liquid crystal panel provided by the first embodiment of the present invention. The plane of the liquid crystal panel is usually divided into a plurality of pixel units. This embodiment takes a typical thin film transistor liquid crystal display as an example for illustration, as shown in figure 1 Shown is the structure of a pixel unit in a liquid crystal panel.

[0034] A typical multi-film layer structure on a color filter substrate starts from the side adjacent to the first base substrate 11, and at least sequentially includes a color resin and a black matrix layer 12, a first protective layer 13, a common electrode layer 14 and a first alignment layer. Membrane 15. The color resin and black matrix layer 12 includes a color filter resin 121 and a black matrix 122 , and the black matrix 122 is arranged between the color filter resins 121 at intervals. The first protection layer 13...

[0047] In the second embodiment of the present invention, the structure of the liquid crystal panel is basically the same as that of the first embodiment. The antenna array includes a first direction wire and a second direction wire perpendicular to each other. The difference is that the first direction wire and the second direction wire cover There is an insulating transparent film layer, that is, when the first direction wire and the second direction wire are formed into the liquid crystal panel, an insulating transparent film layer can be provided on both sides of the first direction wire and the second direction wire respectively, so as to ensure that the first direction wire And the insulation of the second direction wire and the LCD panel.

[0048] In this embodiment, an inner insulating layer 53 may be formed between the first-direction wire 51 and the second-direction wire 52 , so that the first-direction wire 51 and the second-direction wire 52 are kept insulated first...

[0054] In the third embodiment of the present invention, the structure of the liquid crystal panel is basically the same as that of the first embodiment, and the antenna array includes a first direction wire and a second direction wire perpendicular to each other, the difference lies in: the first direction wire and / or the second direction wire The top is covered with an outer interval insulating layer, so as to ensure the insulation between the first direction wire and the second direction wire and the conductive material in the liquid crystal panel.

[0055] With the above technical solution, the first direction wire and the second direction wire can be arranged at any position in the two base substrates of the liquid crystal panel, they can be arranged together and kept insulated by an insulating layer inside, or they can be arranged separately. Still taking the typical color filter substrate and array substrate described in the above-mentioned embodiments as an example for ...

Abstract

An electromagnetic induction type LC panel includes a first substrate and a second substrate facing each other, a liquid crystal layer (63) filled between the first substrate and the second substrate, an antenna array made of conductive material, which is formed between a first base substrate (11) and a second base substrate (21) and insulated from conductive material in multi-film structures, and an input identification circuit connected to an output terminal of the antenna array.

Description

technical field [0001] The invention relates to handwriting input technology, in particular to an electromagnetic induction liquid crystal panel with handwriting input function, a manufacturing method thereof and a liquid crystal display. Background technique [0002] With the development of input technology and display technology, it is a development trend in line with market demand to combine commonly used liquid crystal displays and handwriting input devices. [0003] In the prior art, the following technical solutions are adopted for making the liquid crystal display have the handwriting input function. First of all, handwriting input can be divided into resistive, capacitive and electromagnetic induction according to the realization principle. Resistive and capacitive handwriting input devices receive input signals by recognizing touch actions. Generally, an independent resistive or capacitive handwriting input board is assembled on the outside of the LCD display, that...
