Description
Technical Field
The invention relates to the technical field of display, in particular to an array substrate, a preparation method thereof and a liquid crystal display device.
Background
A liquid crystal display is a display using liquid crystal as a material. Liquid crystals are organic compounds between solid and liquid states, and under the action of an electric field, liquid crystal molecules change in arrangement, so that the change of light passing through the liquid crystal molecules is affected, and the change of light can be represented as a change of brightness through the action of a polarizer. Therefore, people can finally control the brightness change of the light through controlling the electric field, thereby achieving the purpose of displaying images. When the liquid crystal display is applied to the terminal equipment, a touch screen is usually attached to the liquid crystal display, so that the applicability of the liquid crystal display is improved.
The touch panel can be applied in a frame-type or a full-type manner. The frame paste type touch screen is fixed with four sides of the liquid crystal display screen by using double-sided adhesive, and air filled gaps exist between the liquid crystal display screen and the touch screen. The bonding mode liquid crystal display device has good compression resistance, but the reflection between the liquid crystal display screen and the touch screen is obvious, and the display effect is poor.
With the requirement of thinning the liquid crystal display device, the bonding mode of the touch screen is gradually switched into a full bonding mode, and the full bonding mode is a mode of completely bonding the touch screen and the liquid crystal display together in a seamless mode, so that a gap between the liquid crystal display and the touch screen is omitted, and the thickness of the screen is thinner.
At present, because the gap between the liquid crystal display screen and the touch screen is omitted, when the touch screen is subjected to external pressure, the deformation of the touch screen caused by the pressure directly acts on the liquid crystal display, so that the liquid crystal display generates larger deformation, liquid crystal at the pressed position corresponding to the liquid crystal display screen is diffused from a pixel area to a peripheral area, liquid crystal molecules in the peripheral area are gathered, when the liquid crystal is gathered too much, the arrangement of the liquid crystal is disordered, the optical display of the peripheral area and the pixel area is different, and thus poor display is caused, for example, poor water ripple is generated.

The terms "first surface" and "second surface" are used to describe that the surfaces of the piezoelectric material layer 403 that are in contact with the first electrode 401 and the second electrode 402 are two different surfaces. By way of example, the "first surface" may in particular be the lower surface of the layer of piezoelectric material 403, i.e. the side of the layer of piezoelectric material 403 facing the substrate 3; the "second surface" may specifically be an upper surface of the piezoelectric material layer 403, i.e. a side of the piezoelectric material layer 403 facing the liquid crystal layer 9.
In the array substrate provided in the first embodiment of the present invention, the piezoelectric portion 4 is disposed in the peripheral area 2 of the array substrate, when the array substrate is subjected to external pressure, different voltages are applied to the first electrode 401 and the second electrode 402 through different voltage signal terminals respectively connected to the first electrode 401 and the second electrode 402 of the piezoelectric portion 4, so that a voltage difference is formed between the first electrode 401 and the second electrode 402, and due to the inverse piezoelectric effect, the volume of the piezoelectric material layer 403 between the first electrode 401 and the second electrode 402 is shrunk under the action of the external electric field, see fig. 2, so that an excessive space is generated above the piezoelectric portion 4, and the generated excessive space can accommodate liquid crystals that diffuse into the peripheral area 2 due to the external pressure, so that aggregation of the liquid crystals in the peripheral area 2 is avoided, and the liquid crystals in the peripheral area 2 are orderly arranged, and the picture quality of the liquid crystal display device is improved.
Further, the array substrate further includes: a first conductive layer 7, an insulating layer 6, and a second conductive layer 5 which are stacked and arranged on the substrate 3, the first conductive layer 7 and the second conductive layer 5 being in the pixel region 1; in order to simplify the manufacturing process so that the first electrode 401 and the first conductive layer 7 may be simultaneously formed and the second electrode 402 and the second conductive layer 5 may be simultaneously formed during the manufacturing process of the array substrate, it is preferable that the first electrode 401 is provided in the same layer as the first conductive layer 7 and the second electrode 402 is provided in the same layer as the second conductive layer 5. Further preferably, the peripheral region 2 of the insulating layer 6 is provided with a filling groove 601 penetrating the insulating layer 6 corresponding to the first electrode 401 and the second electrode 402, and the piezoelectric material layer 403 is positioned in the filling groove 601, so that the first surface of the piezoelectric material layer is brought into contact with the first electrode, and the second surface of the piezoelectric material layer is brought into contact with the second electrode.
To further simplify the manufacturing process, the first electrode 401 communicates with the first conductive layer 7; the second electrode 402 is isolated from the second conductive layer 5, both of which are connected to the same voltage signal terminal. Thus, the potential of the first conductive layer 7 is the same as that of the first electrode 401, and the first conductive layer and the first electrode share a voltage signal terminal; the second conductive layer 5 has the same potential as the second electrode 402 and shares a voltage signal terminal.

The arrangement and the number of the piezoelectric portions 4 are not particularly limited in this embodiment, and preferably, the piezoelectric portions 4 are arranged in plural at equal intervals in the peripheral region 2, see fig. 3. The plurality of piezoelectric parts 4 are arranged at equal intervals in the peripheral area 2, so that more liquid crystals which are diffused to the peripheral area 2 due to external pressure can be accommodated, the liquid crystals in the peripheral area 2 are arranged more orderly, and the picture quality of the liquid crystal display device is further improved.
For the selection of the piezoelectric material, since a deposition process is generally used for preparing the internal film layer of the liquid crystal display device, the material for forming the piezoelectric material layer 403 is preferably an inorganic piezoelectric material, and the inorganic piezoelectric material is an inorganic small molecular material, so that a film is more easily formed in the deposition process.
Example two
The structure of the array substrate according to the second embodiment of the present invention is substantially the same as that of the first embodiment, and the difference is that the piezoelectric portions 4 are arranged.
The piezoelectric portion 4 of the second embodiment of the present invention is a frame, see fig. 4. The whole peripheral region 2 is provided with the piezoelectric part 4, so that more liquid crystals which are diffused to the peripheral region 2 due to external pressure can be contained, the liquid crystals in the peripheral region 2 are arranged more orderly, and the picture quality of the liquid crystal display device is further improved.

The liquid crystal display device provided by the third embodiment of the invention is particularly suitable for a touch liquid crystal display device prepared in a full-lamination mode. The full-attaching mode is a mode that the touch screen and the liquid crystal display screen are completely attached together in a seamless mode, and because the device omits a gap between the liquid crystal display screen and the touch screen, when the touch screen is subjected to external pressure, the touch screen directly acts on the liquid crystal display due to deformation generated by the pressure, so that the liquid crystal display generates larger deformation, liquid crystal at a pressed position corresponding to the liquid crystal display screen is diffused from a pixel area to a peripheral area, liquid crystal molecules in the peripheral area are gathered, when the liquid crystal is gathered excessively, the arrangement of the liquid crystal is disordered, the optical display of the peripheral area and the pixel area is different, and thus poor display, for example, poor water ripple, is generated. When the touch screen is subjected to external pressure, the touch screen directly transmits the pressure to the liquid crystal display device, and the piezoelectric part 4 with the inverse piezoelectric effect is contracted in volume, so that an extra space is generated above the piezoelectric part 4, the generated extra space can contain liquid crystal which is diffused to the peripheral area 2 due to the external pressure, aggregation of the liquid crystal in the peripheral area 2 is avoided, the liquid crystal in the peripheral area 2 is orderly arranged, and the picture quality of the touch type liquid crystal display device prepared in a full-lamination mode is improved.
