FIG. 1 shows a schematic structural view of the present utility model;

fig. 2 shows a schematic diagram of a prior art structure.

In the drawings, the list of components represented by the various numbers is as follows:

1. a cover plate; 2. a front light guide plate; 3. an optical bonding layer; 4. a reflective liquid crystal display; 5. a light source; 6. a screen; 7. a transmissive liquid crystal screen; 8. and a backlight plate.

Detailed Description

The principles and features of the present utility model are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the utility model and are not to be construed as limiting the scope of the utility model.

Examples

As shown in fig. 1, the present embodiment provides a reflective low blue light liquid crystal display, which includes: the light source device comprises a cover plate 1, a front light guide light plate 2 and a reflective liquid crystal display screen 4, wherein the cover plate 1, the front light guide light plate 2 and the reflective liquid crystal display screen 4 are sequentially arranged from top to bottom, the cover plate 1 is fixedly connected with the periphery of the front light guide light plate 2, a light source 5 is arranged on one side of the front light guide light plate 2, and an optical bonding layer 3 for filtering harmful blue light is arranged between the front light guide light plate 2 and the reflective liquid crystal display screen 4.

It should be noted that the optical bonding layer 3 in the present application uses an optical bonding material, which has two morphological modes, i.e. a liquid optical glue and a solid optical double-sided tape, and the main components of the optical bonding material are two optical acrylic resins or optical silicone resins. The material for filtering blue light in the optical bonding layer is mainly a material capable of absorbing harmful blue light, such as a benzotriazole blue light absorbing material, and the materials are as follows: 1% by weight is added to the optical-grade acrylic resin or to the optical-grade silicone resin.

In this embodiment, the light source 5 is an LED lamp, which is efficient, energy-saving, long in service life, and environment-friendly.

In this embodiment, the cover plate 1 is fixedly connected with the peripheral edge of the front light guiding plate 2 through double faced adhesive tape, so that the fixing effect is good, the assembly and the disassembly are convenient, and the transmission of the light path is not affected by the connection of the peripheral edge of the front light guiding plate 2.

In this embodiment, the reflective liquid crystal display 4 is a passive display, and the display effect is achieved by reflecting ambient light under the condition of sufficient light, the display itself does not emit light, and the stronger the ambient light is, the clearer and brighter the display is; under the condition that the ambient light is relatively dark, a part of light needs to be compensated by opening the front light to achieve the effect that the screen display is clear and bright, and the reflective liquid crystal display screen 4 does not cause eyestrain, dryness and eye injury.

As shown in fig. 1, the front light guiding plate 2 and the reflective liquid crystal screen 4 are fully attached together through the optical attaching layer 3, an LED lamp is added on one side of the front light guiding plate 2 as a light source 5, when the LED lamp is turned on, light is transmitted in the front light guiding plate 2 through the front light guiding plate 2, and due to the design of the front light guiding plate 2, part of the light cover plate 1 is transmitted in the direction of the reflective liquid crystal screen 4, namely downward, after reaching the reflective liquid crystal screen 4, the light is reflected by the reflective liquid crystal screen, and then the light is reflected out to achieve the display effect; light passes through the optical bonding layer 3 twice in the transmission process, and the harmful blue light is filtered in the twice transmission process because the optical bonding layer 3 has the function of filtering the harmful blue light, so that only the light beneficial to eyes is transmitted out to achieve the effect of protecting eyes.

Fig. 2 shows a structure of a conventional transmissive lcd, in which light passes through a backlight plate 8 directly through a transmissive lcd 7 and then emits light to achieve the display purpose, and air is arranged between the backlight plate 8 and the screen 6 without a filter layer, so that there is no way to filter harmful blue light to achieve the effect of protecting eyes with low blue light.
