DETAILED DESCRIPTION

[0026] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model.

[0027] Embodiment 1

[0028] Please refer to Figures 1 to 7 The utility model discloses a kind of displays without backlight, by installing reflective sheet in the front end surface position of frame 1, to improve the utilization of ambient light in this way, while the cooperation of assembly strip 4 and strip plate 2 is used, it is convenient to carry out quick assembly and disassembly work to reflective sheet.

[0029] Specifically, frame 1;The inside of frame 1 is sequentially provided with front and rear abutting front protective layer 101, transparent electrode layer 102, display medium layer 103, reflective layer 104 and TFT backboard 105 from front to back, the front end of frame 1 is provided with strip plate 2 in front protective layer 101 left and right sides, the position of the inner arc part 201 of the two strip plates 2 relatively arranged is provided with reflective sheet 3, the rear end surface of strip plate 2 is provided with assembly strip 4 connected with the rear end of frame 1, the rear end surface of frame 1 connected with assembly strip 4 is provided with assembly hole 108, the end surface of assembly strip 4 is fixed with multiple assembly rods 401 respectively inserted in the inside position of assembly hole 108, the rear end of frame 1 is provided with mounting port 107, the position of mounting port 107 is provided with locking plate 106 bolted with frame 1.

[0030] The operation process of this embodiment is as follows: By setting and using the above structure, the external light is reflected by the reflector 3, so that the light is reflected to the end face of the frame 1, and then reflected by the reflective layer 104, thereby improving the utilization rate of ambient light. At the same time, when the reflector 3 is removed, the mounting strip 4 is moved away from the strip plate 2. As a result, the mounting strip 4 will drive the mounting rod 401 to move out of the mounting hole 108, so that the mounting strip 4 and the strip plate 2 will not be mounted on the frame 1, and the strip plate 2 can be removed from the frame 1. The front protective layer 101 used is located at the frontmost position inside the frame 1, which realizes scratch resistance and impact resistance. The transparent electrode layer 102 used forms an electric field to drive the display particles. At the same time, the display medium layer 103 controls the arrangement of liquid crystal molecules through the electric field to adjust the light reflectivity. The reflective layer 104 improves the reflectivity of ambient light, and precisely drives the display particles or liquid crystal by controlling the electric field of each pixel of the TFT back plate 105.

[0031] Example 2

[0032] Please see Figure 5 and Figure 6 Based on Example 1, the angle rod 301 can be rotated in the angle hole 204 to adjust the angle of the reflector 3.

[0033] Specifically, both ends of the two inner arc portions 201 are fixed with protrusions 205, and the two protrusions 205 on each inner arc portion 201 are provided with angle holes 204 through the two protrusions 205. The protrusion of the reflector 3 is fixed with two angle rods 301 that are respectively inserted into the angle holes 204, and the protrusion of the reflector 3 is located between the two adjacent protrusions 205.

[0034] The operation process of this embodiment is as follows: When adjusting the emission angle of the reflector 3, the reflector 3 can be directly controlled to rotate in the position of the inner arc 201, thereby controlling the rotation of the angle rod 301 inside the angle hole 204. The protrusions on the surface of the angle rod 301 rotate one by one in the recessed position inside the angle hole 204, thereby ensuring the stability of the position of the reflector 3 after the angle is adjusted. When the angle of the reflector 3 is adjusted, its emission angle to ambient light will also shift, so it can be adjusted according to the user's usage habits.

[0035] Example 3

[0036] Please see Figure 3 , Figure 4 and Figure 6 Based on Example 1, the installation stability of the assembly strip 4 and the strip plate 2 can be improved by pushing the round block 403 with the spring 404.

[0037] Specifically, the upper and lower parts of the front end of the assembly strip 4 are fixed with moving rods 402, the rear end face of the strip-shaped plate 2 is provided with limiting holes 203 corresponding to the positions of the moving rods 402, the inner end part of each limiting hole 203 is provided with a moving hole 202, the end face of the moving rod 402 penetrating through the moving hole 202 is fixed with a circular block 403 which is in contact with the inner wall of the moving hole 202, the aperture of the moving hole 202 is larger than that of the limiting hole 203, the moving rod 402 at the inner part of the moving hole 202 is sleeved with a spring 404, and the end part of the spring 404 is in contact with the end face of the moving hole 202 and the end face of the circular block 403 respectively.

[0038] The operation process of the embodiment is as follows: when the moving rod 402 slides in the limiting hole 203, the moving rod 402 drives the circular block 403 to slide in the moving hole 202 and compresses the spring 404, so that when the assembly strip 4 and the strip-shaped plate 2 are assembled on the frame 1, the circular block 403 is pushed by the spring 404, and the assembly strip 4 is tightly attached to the frame 1.
