[0022] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0023] This application proposes an anti-peeping display structure 100, see Figure 1 and Figure 2, including: an upper glass substrate 10, a lower glass substrate 20, a CF layer 30 and a liquid crystal layer 40. The liquid crystal layer 40 is sandwiched between the upper glass substrate 10 and the lower glass substrate 20. The liquid crystal layer 40 contains flowing liquid crystals, and different patterns are presented when different voltages are applied. The upper glass substrate 10 and the lower glass substrate 20 are both translucent glass with good light transmittance, and circuit plates are respectively made on the upper glass substrate 10 and the lower glass substrate 20, so that different voltages can be applied to the liquid crystal layer 40, thereby changing the arrangement of the liquid crystals, so that the liquid crystal layer 40 presents different patterns or texts. A CF layer 30 is provided between the liquid crystal layer 40 and the upper glass substrate 10. The CF layer 30 includes a color filter and a plurality of anti-peeping horizontal stripes 31. The anti-peeping horizontal stripes 31 are arranged in parallel. The anti-peeping horizontal stripes 31 are filled with color filters. The anti-peeping display structure 100 is installed in the display module, and there is no need to attach an anti-peeping film to the display screen of the display module. Only the user who is using the display module can see the picture in the display module, and others cannot observe the picture in the display module outside a certain viewing angle A, thereby preventing work information or privacy from being peeped, thereby achieving the anti-peeping technical effect. Preferably, the ratio of the height to the width of the anti-peeping horizontal strip 31 is 0.866.

[0024] In one embodiment, the anti-peeping horizontal strip 31 is arranged on the light-transmitting plate 32 and the upper glass substrate 10 in the vertical direction, so that the user in use can see the picture in the vertical direction or in the center of the display module, but cannot observe the picture in the display module from the left and right sides. Figure 1 The anti-peeping display structure 100 also includes a TFT circuit board 50. The TFT circuit board 50 is very thin and has good light transmittance. The TFT circuit board 50 is disposed between the liquid crystal layer 40 and the lower glass substrate 20. The two circuit plates are electrically connected to the TFT circuit board 50 respectively. The external current is controlled and the voltage is converted by the TFT circuit board 50, so that the liquid crystal of the liquid crystal layer 40 presents different patterns, thereby showing a better display effect. In one embodiment, please refer to Figure 1 The anti-peeping horizontal strip 31 is consistent in size with the upper glass substrate 10 and the lower glass substrate 20, so that the display screen on the display module is fully anti-peeping, further improving the anti-peeping effect. Figure 2 The viewing angle A of the anti-peeping horizontal bar 31 in the CF layer 30 is 60 degrees, which ensures the viewing experience of the user while preventing people from far away from observing. In order to take into account the effects of anti-peeping and display, the anti-peeping horizontal bar 31 is set as a rectangular parallelepiped structure.

[0025] The present application also proposes a display module, including the above-mentioned anti-peeping display structure 100, and also including: a backlight assembly, an upper polarizer, a lower polarizer and a cover plate. The anti-peeping display structure 100 is arranged between the upper polarizer and the lower polarizer, and the upper polarizer and the lower polarizer can selectively filter out light in certain directions and only allow light in a specific direction to pass through to adjust to a softer picture. The upper polarizer is provided with a cover plate on the side away from the anti-peeping display structure 100, and the lower polarizer is provided with a backlight assembly on the side away from the anti-peeping display structure 100. The backlight assembly is used to illuminate the anti-peeping display structure 100 so that the user can observe the picture, and there is no need to attach an anti-peeping film to the display screen of the display module. Preferably, the cover plate is a TP cover plate or a PMMA cover plate. In addition, a light source assembly is provided on the backlight assembly for lighting, and the light source assembly is a plurality of LED lamps. In order to enhance the brightness of the picture, the brightness of the picture can be improved according to the number of LED lamps set, so that the picture is more delicate and soft.

[0026] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
