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 structural diagram of the electromagnetic induction type 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 description, such as figure 1 Shown is the structure of a pixel unit in a liquid crystal panel.

[0034] A typical multi-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 black matrix layer 12, a first protective layer 13, a common electrode layer 14 and a first orientation 膜层15。 Film layer 15. The color resin and black matrix layer 12 includes a color film resin 121 and a black matrix 122, and the black matrix 122 is arranged between the color film resin 121 at intervals. The first protective layer 13 is generally m...

[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 first-direction wires and second-direction wires that are perpendicular to each other. The difference is: the first-direction wires and the second-direction wires are covered 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 to ensure the first direction wire And the second direction wire is insulated from the liquid crystal panel.

[0048] In this embodiment, the first-direction wire 51 and the second-direction wire 52 may be formed with an inner space insulating layer 53, and the first-direction wire 51 and the second-direction wire 52 are 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. The antenna array includes first-direction wires and second-direction wires that are perpendicular to each other. The difference is: first-direction wires and / or second-direction wires The upper is covered with an outer space 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] By adopting the above technical solution, the first-direction wires and the second-direction wires can be arranged at any position in the two base substrates of the liquid crystal panel, and can be arranged together so that the insulating layer is kept insulated within the space, or they can be arranged separately. Still taking the typical color filter substrates and array substrates described in the above embodiments as examples for...

Abstract

The invention relates to an electromagnetic induction type liquid crystal panel as well as a manufacture method thereof and a liquid crystal display (LCD). The liquid crystal panel comprises a first base plate and a second base plate cassette to cassette, wherein a liquid crystal layer is filled between the first base plate and the second base plate; the liquid crystal panel also comprises an antenna array; the antenna array is made of conducting materials, formed between the first substrate base plate and the second substrate base plate and insulated from the conducting materials in a multi-film layer structure; and the antenna array is used for recognizing an electromagnetic signal. The LCD of the invention comprises the electromagnetic induction type liquid crystal panel and also comprises an input recognizing circuit which is connected with the output end of the antenna array. By adopting a technical approach for integrating the antenna array in the liquid crystal panel, the invention meets the light-weight and thin requirement of the LCD and reduces the assembly cost.

Description

Technical field [0001] The invention relates to handwriting input technology, in particular to an electromagnetic induction type 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, the combination of commonly used liquid crystal displays and handwriting input devices is a development trend that meets market needs. [0003] In the prior art, there are several technical solutions adopted to enable a liquid crystal display to have a handwriting input function. First of all, handwriting input can be divided into resistive type, capacitive type and electromagnetic induction type according to the realization principle. Resistive and capacitive handwriting input devices recognize touch actions to receive input signals. Generally, independent resistive or capacitive handwriting input boards are assembled on the outside of the liquid...
