Embodiment 1

[0030] Such as Figure 1 to Figure 2 As shown, the front light structure of a reflective liquid crystal screen used in a low-light environment described in the embodiment of the present invention includes a reflective material 1, a reflective liquid crystal screen 11, a front light guide plate 12, and a touch panel stacked sequentially from bottom to top. 13 and protective glass 14; the reflective liquid crystal screen 11 is attached to the front light guide plate 12 with OCA glue, the front light strip 15 receives light from the long side of the front light guide plate 12, the front light guide plate 12 is attached to the touch panel 13 with OCA glue, and the touch 13 Use OCA glue to fit the protective glass 14; the front light bar 15 protrudes from the protective glass 14; when the ambient light is insufficient, the front light bar 15 is turned on to evenly irradiate the reflective material 1, thereby meeting the requirement of reflective liquid crystal. The display light co...

Embodiment 2

[0038] Such as Figure 7 Shown, comparative example one, wherein another kind of implementation mode of the present invention is:

[0039] The movable contact piece 36 is arc-shaped, and two slide holes are provided on the movable contact piece 36, and the arc rod 4 is slidably connected in the slide hole, and the two ends of the arc rod 4 are fixedly connected with graphite balls 41; There is a spring fixedly connected between the middle part of the shaped rod 4 and the swing rod 35; the contact area between the movable contact piece 36 and the static contact piece 37 is increased by the arc-shaped rod 4 and the graphite ball 41, and the ablation caused by the poor contact of the movable contact piece 36 is reduced At the same time, a small amount of graphite powder formed by graphite ball 41 is lubricated to increase the contact efficiency between the moving contact piece 36 and the static contact piece 37 and reduce wear.

[0040] The static contact piece 37 is fixedly con...

Abstract

The invention belongs to the technical field of display, and particularly relates to a reflective liquid crystal screen front light structure used in a weak light environment, which comprises a reflective material, a reflective liquid crystal screen, a front light guide plate and touch and protective glass which are sequentially overlapped from bottom to top, the reflective liquid crystal screen is attached to the front light guide plate through OCA glue, the front light bar enters light from the long edge of the front light guide plate, the front light guide plate is attached to the touch screen through the OCA glue, and the touch screen is attached to the protective glass through the OCA glue. The front light bar protrudes out of the protective glass. When the ambient light is insufficient, the front light bar is turned on, and the light is uniformly irradiated on the reflective material, so that the display light condition of the reflective liquid crystal screen is met, and the structure can be normally used when no ambient light exists.

Description

technical field [0001] The invention belongs to the field of display technology, in particular to a front light structure of a reflective liquid crystal screen used in a weak light environment. Background technique [0002] The reflective display screen is equipped with reflective material under the liquid crystal panel to replace the luminescent material of the transmissive display screen. When the ambient light is sufficient, it uses the light reflected by the mirror to illuminate the screen. However, it has the problem of not being able to display clearly when it reaches a place with low light, because the weak ambient light is not reflected enough to illuminate the screen. [0003] Therefore, how to solve the problem that the reflective display screen can be seen clearly when the light is dark or there is no light has become a problem that those skilled in the art wish to solve. [0004] Therefore, the present invention provides a front light structure of a reflective l...
