Most reflective polarizers have a gray background color, and the cost of color adjustment is high, making it difficult to meet the personalized needs of users.

[0029] Next, embodiments of the present application will be described in detail with reference to the drawings.

[0030] Combined Figure 1 and Figure 2 As shown, the reflective LCD display panel 100 includes a transmissive polarizer 10, a liquid crystal panel 20, an ink layer 30, and a reflective polarizer 40 arranged from top to bottom;

[0031] Among them, the liquid crystal panel 20 includes an upper substrate 21 close to the transmissive polarizer 10, a liquid crystal layer (not shown in the figure), and a lower substrate 22 close to the reflective polarizer 40.

[0032] The ink layer 30 is a transparent color ink layer, and is an ink layer screen-printed on the surface of the lower substrate 22 away from the liquid crystal layer. Optionally, the thickness range of the ink layer 30 is 0.5 micrometers to 0.9 micrometers.

[0033] It should be noted that during implementation, the ink layer 30 is formed on the lower surface of the lower substrate 22 through screen printing. The lower substrate 22 here can specifically be a separate lower substrate 22 to be made into a liquid crystal panel, or the lower substrate 22 of a liquid crystal panel that has already been made. This application does not make specific restrictions on this.

[0034] It can be understood that the upper substrate 21 and the lower substrate 22 in this application can be glass substrates or substrates made of other applicable materials. This application also does not make specific restrictions on this.

[0035] According to the reflective LCD display panel provided by this application, on the one hand, through the laminated structure of the reflective polarizer 40 and the ink layer 30, based on the transparent performance of the ink layer 30, it can basically not affect the light valve function of the reflective polarizer 40; and based on the color performance of the ink layer 30, it can reflect corresponding colored light to the ambient light, thus effectively meeting the personalized needs of users. On the other hand, by disposing the ink layer 30 on the lower surface of the lower substrate 22, compared with improving the color function of the reflective polarizer 40, the rework cost is lower and the application flexibility is higher. Moreover, since the ink layer 30 is prepared by the screen printing method, the process cost of the lower substrate 22 with the ink layer 30 attached is lower and the quality of the ink layer 30 is higher.

[0036] In one embodiment, the ink layer 30 is a background color layer covering the visible area of the LCD display panel 100. In another embodiment, the ink layer 30 is a pattern layer corresponding to the visible area of a partial LCD display panel 100. That is, the ink layer 30 can be a background color layer covering the entire visible area or a specific pattern layer corresponding to a part of the visible area. This application does not make specific restrictions on this. It can be determined according to the product requirements specifically, thereby further improving the personalized function.

[0037] In one embodiment, the light transmittance of the liquid crystal panel 20 is 88% - 92%.

[0038] As an example, the ink layer 30 is an orange ink layer; the light transmittance of the liquid crystal panel 20 printed with the ink layer 30 is 78% - 82%. As another example, the ink layer 30 is a gold ink layer 30; the light transmittance of the liquid crystal panel 20 printed with the ink layer is 74% - 78%.

[0039] That is to say, for different color systems, the light transmittance of the preferred ink layer is matched to balance achieving better color effects and light valve control effects.

[0040] In one embodiment, the ink of the ink layer 30 is an ink prepared by mixing corresponding pigments or dyes into a urethane base paste. Further optionally, the viscosity range of the ink is from 2000 pascal seconds to 3000 pascal seconds, so as to form a high-quality screen printing ink layer.

[0041] Optionally, a gray background reflection layer is provided on the surface of the reflective polarizer 40 away from the ink layer 30. The reflective polarizer 40 realizes light reflection through this gray background reflection layer.

[0042] This application also provides a display, such as Figure 3 As shown, the display 1000 includes the reflective LCD display panel 100 in the above embodiment.

[0043] In summary, for the reflective LCD display panel and the display according to the embodiments of this application, through the laminated structure of the reflective polarizer and the ink layer, based on the transparent color performance of the ink layer, it can basically not affect the light valve function of the reflective polarizer, and can reflect corresponding colored light to the ambient light, thereby effectively meeting the personalized needs of users. And by arranging the ink layer on the lower surface of the lower substrate, compared with improving the color function of the reflective polarizer, the rework cost is lower and the application flexibility is higher. Moreover, by using the screen printing method to prepare the ink layer, the process cost of the lower substrate with the ink layer is lower and the quality of the ink layer is higher. Thus, a reflective display panel with a colored background can be realized, which meets the personalized needs of users, has low cost and high application flexibility.
