Description

Technical Field

[0001] The present application relates to the field of liquid crystal display technology, and in particular to a liquid crystal module for realizing positive and negative display. Background Art

[0002] LCD monochrome liquid crystal display modules usually have two display types: positive display and negative display.

[0003] Positive display means that the color of the content displayed by the LCD module is darker than the background color. For example, if the background is a natural color and the text is black, the color of the text is darker than the background color, which is positive display.

[0004] Negative display means that the color of the content displayed by the LCD module is lighter than the background color. For example, if the background is black and the text is white, the color of the text is lighter than the background color, which is negative display.

[0005] In the prior art, a positive display liquid crystal display module and a negative display liquid crystal display module are assembled together to achieve a positive display and a negative display effect.

[0006] However, due to the surrounding plastic frames in the LCD production process, the two liquid crystal display modules cannot fit closely together, and the structure is complex, the cost is high, the production efficiency is low, and the display and structural requirements of customers cannot be met. Summary of the invention

[0007] In view of this, the embodiments of the present application provide a liquid crystal module that realizes positive and negative display, so as to overcome the technical problems of the liquid crystal module in the prior art, such as complex structure, high cost and low production efficiency.

[0010] A green silk screen is provided on the first area of ​​the lower glass substrate, and a red silk screen is provided on the second area of ​​the lower glass substrate;

[0011] The lower polarizer has different polarization properties from the regions corresponding to the first region and the second region.

[0012] In some embodiments, the lower polarizer includes two polarizers with different polarization properties.

[0013] In some embodiments, a black silk screen is disposed at the junction of the first area and the second area on the lower glass substrate.

[0014] In some embodiments, a first pin is led out from the upper ITO layer.

[0015] In some embodiments, a second pin is led out from the lower ITO layer.

[0016] In some embodiments, the first pin and the second pin are distributed on the same side of the upper ITO layer and the lower ITO layer, and are located at two different ends.

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0025] In the embodiment of the present application, a liquid crystal module for realizing positive and negative display is provided. By adopting the same liquid crystal module, the lower polarizer has different polarization properties in the areas corresponding to the first area and the second area. The structure is simple, the production cost is reduced, and the production efficiency is improved.

[0026] Specifically, Figure 1 FIG. 1 is a schematic diagram of the overall structure of a liquid crystal module for realizing positive and negative display according to an embodiment of the present application. In this embodiment, the liquid crystal module for realizing positive and negative display includes:

[0027] The upper polarizer 1, the upper glass substrate 2, the upper ITO layer 3, the liquid crystal 4, the lower ITO layer 6, the lower glass substrate 7 and the lower polarizer 8 are arranged in sequence from top to bottom, and the rubber frame is arranged on the surrounding side of the upper ITO layer 3, the liquid crystal 4 and the lower ITO layer 6. The connection relationship between the upper polarizer 1, the upper glass substrate 2, the upper ITO layer 3, the liquid crystal 4, the lower ITO layer 6, the lower glass substrate 7 and the lower polarizer 8 is the same as that in the prior art, and will not be described in detail in this embodiment. Among them, the upper ITO layer 3, the liquid crystal 4 and the lower ITO layer 6 are all sealed with rubber frames.

[0028] Among them, a green silk screen is set on the first area of ​​the lower glass substrate 7, and a red silk screen is set on the second area of ​​the lower glass substrate 7 to provide different background colors, thereby achieving the effect of positive and negative display. Specifically, the lower glass substrate 7 can be divided into the first area and the second area set on the left and right according to actual needs. Of course, the area division can also be performed according to actual needs. For example, the area of ​​the first area can be larger than the second area, or the area of ​​the second area can be larger than the first area.

[0029] The lower polarizer 8 and the regions corresponding to the first region and the second region of the lower glass substrate 7 have different polarization properties.

[0030] In some specific embodiments of the present application, the lower polarizer includes two polarizers with different polarization properties, that is, two polarizers with different polarization properties are used, and the two polarizers are in close contact.

[0031] In some specific embodiments of the present application, in order not to affect the display effects of the first area and the second area, that is, the positive and negative displays do not interfere with each other, a black silk screen is provided at the junction of the first area and the second area on the lower glass substrate to clearly divide the positive display area and the negative display area.

[0032] The liquid crystal module for realizing positive and negative display in the embodiment of the present application adopts the same liquid crystal module, and the polarization properties of the lower polarizer and the areas corresponding to the first area and the second area are different, so the structure is simple, the production cost is reduced, and the production efficiency is improved.

[0033] In addition, as some other embodiments of the present application, Figure 2 As shown, it is a schematic diagram of the pin lead-out of the liquid crystal module for realizing positive and negative display in an embodiment of the present application. Among them, the upper ITO layer leads to a first pin 301, and the lower ITO layer leads to a second pin 601. And the first pin 301 and the second pin 601 are distributed on the same side of the upper ITO layer and the lower ITO layer, and are located at different ends. For example, the first pin 301 and the second pin 601 are both located on the lower side of the upper ITO layer and the lower ITO layer, the first pin 301 can be located on the left side of the ITO layer, and the second pin 601 can be located on the right side of the lower ITO layer, or the positions can be swapped.

[0034] Figure 3 The power-on and power-off display effects of the liquid crystal module for realizing positive and negative display according to the embodiment of the present application are shown. In this embodiment, in the power-off state, the background color of the left area of ​​the liquid crystal module for positive and negative display is darker, and in the power-on state, the background color of the right area of ​​the liquid crystal module for positive and negative display is darker.

[0035] This embodiment can achieve similar technical effects as the embodiment 1, and will not be repeated here.

[0036] The above specific implementations do not constitute a limitation on the protection scope of this application. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included in the protection scope of this application.
