[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 a display module 10, see Figure 1 , including a light guide plate 11, a light source assembly 20 and a housing 30. The housing 30 is provided with a groove, the groove accommodates the light guide plate 11 and the light source assembly 20, the light source assembly 20 is arranged on the side of the groove, the light guide plate 11 is arranged at the bottom of the groove, a light diffuser 12 is arranged on one side of the light guide plate 11, and the light diffuser 12 is arranged on the opposite side of the light guide plate 11 away from the bottom of the groove. The light diffuser 12 is used to evenly transmit the light emitted by the light source assembly 20 through the surface of the light guide plate 11 to achieve the effect of the light diffuser film in the market. Compared with the prior art, the use of the film material of the light diffuser film is reduced, the labor cost and the manufacturing difficulty are reduced, and the manufacturing efficiency is improved. It is suitable for small key-type devices that do not require ultra-high light uniformity and strong light, such as: door password display screens, POS machines, card readers, etc.

[0024] It should be noted that the light emitted by the light source assembly 20 is adjusted by the light guide and the diffuser 12 in turn, and then refracted to the outside from the diffuser 12. The light guide plate 11 and the diffuser 12 are both made of materials with excellent light transmittance, so that the light emitted by the light source assembly 20 is evenly transmitted through the surface of the light guide plate 11.

[0025] Furthermore, the length of the diffuser 12 is equal to the length of the light guide plate 11, and the width of the diffuser 12 is equal to the width of the light guide plate 11, so that the diffuser 12 just covers the light guide plate 11, so that all the light entering the light guide plate 11 is evenly scattered, so as to be closer to the effect of the diffuser film on the market.

[0026] In one embodiment, the diffuser 12 is configured as diffuser patterns, which are consistent with the patterns of diffuser films on the market, achieving the diffuser effect of diffuser films at a low cost. In another embodiment, the diffuser 12 is configured as a plurality of particles, achieving the diffuser effect of diffuser films.

[0027] Preferably, the light source assembly 20 is a plurality of LED lamps. The LED lamps use cold light sources with little glare and no radiation, can protect the eyes of users, and have a long life.

[0028] In one embodiment, please refer to Figure 1 and Figure 2 The display module 10 further includes a touch panel 40, which is disposed on the side of the light diffuser 12 away from the light guide plate 11 and can be applied to more working scenarios, such as a door password display screen. The touch panel 40 is provided with light-transmitting key characters 41, so that the user can accurately operate the display module 10, thereby improving the user experience. The touch panel 40 is in a rectangular shape to meet the aesthetic tastes of most users.

[0029] Preferably, the housing 30 is a plastic housing made of rubber, which has a certain buffering effect and can better protect the components in the housing 30. In addition, the display module 10 also includes a liquid crystal display component 50, which is used to display images to meet more usage scenarios. Specifically, the liquid crystal display component 50 is arranged between the light diffuser 12 and the touch panel 40.

[0030] 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.
