Detailed Description
To describe the structure of the liquid crystal display device of the present invention in detail, specific embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 1 shows a schematic structure of a liquid crystal display device according to an embodiment of the present invention.
As shown in fig. 1, the liquid crystal display device of the embodiment of the present invention includes an upper substrate, a lower substrate, a liquid crystal panel 3 between the upper substrate and the lower substrate, and a controller, which are arranged in parallel; wherein, one side of the lower substrate is provided with a backlight source 4, and the backlight source 4 comprises an LED lamp module electrically connected with the controller; and, LED lamp module is regular quadrangle or circular and arranges on backlight 4.
Specifically, the lower substrate includes a first substrate 23, a first polarizing layer 22, and a first functional layer 21, which are sequentially disposed, the first functional layer 21 being disposed on a side of the first substrate 23 close to the liquid crystal panel 3; the upper substrate comprises a second polarizing layer 11, a second substrate 12 and a second functional layer 13 which are arranged in sequence, and the second functional layer 13 is arranged on one side of the second substrate 12 close to the liquid crystal panel 3; one side of the first substrate 23 is disposed opposite the backlight 4.
The first polarizing layer 22 and/or the second polarizing layer 11 may be an iodine-based polarizing layer, a dye-based polarizing layer, or a metal grating polarizing layer.
In one embodiment of the invention, the lower substrate is a color film substrate, and the upper substrate is a TFT array substrate; or the upper substrate is a color film substrate, and the lower substrate is a TFT array substrate. The liquid crystal display has the working principle that liquid crystal molecules are placed in two parallel substrates (including an upper substrate and a lower substrate), the orientation of the liquid crystal molecules is controlled by whether the substrates are electrified or not, the polarization state of light of the backlight module is changed, and the light path is penetrated and blocked by the polarizing plates arranged at two sides of the liquid crystal display panel, so that the purpose of controlling the light transmission amount is achieved; the light passing through the liquid crystal panel 3 is filtered and absorbed by the color photoresist layer, so that the light of each pixel is composed of three primary colors (RGB) after being emitted, different pixels correspondingly emit light with different colors, and the full-color display is realized by utilizing the spatial color mixing principle. It can be seen that polarized light and the three primary colors of RGB are two of the most important elements for realizing the display principle.
Further, the manufacturing principle of the iodine-based polarizing layer and the dye-based polarizing layer is as follows: soaking a high polymer film such as polyvinyl alcohol (PVA) in a solution containing multivalent iodide ions or a polarizing dye, and stretching the PVA polymer in a single-axis direction; the PVA molecules are arranged in one direction after being stretched by an external force, so that iodine molecules or dye molecules adsorbed on the PVA molecules are arranged in the same direction as the PVA molecules; the stretched slender iodine molecules or dye molecules can absorb light vibrating in the direction parallel to the long axis of the iodine molecules and transmit the light vibrating in the direction perpendicular to the long axis of the iodine molecules, and then the polaroid (or polarizing layer) capable of forming polarized light is obtained. In addition, the first polarizing layer 22 and the second polarizing layer 11 of the present invention may also adopt a metal grating structured polarizing layer.
In the liquid crystal display of the embodiment of the invention, the LED lamp modules are arranged on the backlight source 4 in a diamond shape or a circular shape, and the controller controls the LED lamp modules in an annular scanning mode to reduce the scanning lines of the controller; in addition, the liquid crystal panel 3 can also adopt a black transparent plate-shaped structure, and when the backlight 4 is not electrified and the LED lamp modules do not shine, Chinese characters or letters and the like combined by the LED lamp modules can be seen through the liquid crystal panel 3, and the liquid crystal panel can be used in emergency under the condition of emergency.
According to the liquid crystal display provided by the invention, PI (Polyimide) alignment films are not required to be arranged on the upper substrate and the lower substrate, the first polarizing layer of the lower substrate is designed to be built-in, and the first substrate of the lower substrate is used as a light guide plate of the lateral backlight source, so that an additional light guide plate is not required to be arranged, the whole structure of the liquid crystal display is simple and ultrathin, and the user experience is good.
The liquid crystal display proposed according to the present invention is described above by way of example with reference to the accompanying drawings. However, it will be appreciated by those skilled in the art that various modifications may be made to the liquid crystal display proposed by the present invention without departing from the scope of the invention. Therefore, the scope of the present invention should be determined by the contents of the appended claims.
