Embodiment 1

[0024] The orientation names such as "front", "rear", "left" and "right" described in this specification are determined according to the schematic diagrams used in this specification.

[0025] like Figure 1-2 A light-leakage-proof liquid crystal display screen of a mobile phone is shown, comprising a frame 1, a liquid crystal display screen body 2 and a backlight assembly 5. The backlight assembly 5 is integrally formed and fixed on the rear side of the liquid crystal display screen body 2 and the liquid crystal display screen body is integrally formed. 2 and the backlight assembly 5 are clamped and fixed on the inner wall of the limiting cavity 3 inside the frame 1; the backlight assembly 5 includes a parallel beam layer 6, a beam adjustment layer 7, a polarizer 8 and a light source emission layer 9. The parallel beam The layer 6 is closely fixed on the rear side of the liquid crystal display body 2, the beam adjustment layer 7 is closely fixed on the rear side of the parall...

Embodiment 2

[0027] The orientation names such as "front", "rear", "left" and "right" described in this specification are determined according to the schematic diagrams used in this specification.

[0028] like Figure 1-5 A light-leakage-proof liquid crystal display of a mobile phone is shown, including all the technical features of Embodiment 1, the parallel beam layer 6 includes at least one parallel beam layer, and the parallel beam layer includes a condensing bevel 11 and a convex lens 12. The condensing bevel 11 is located at the inner bottom of the parallel beam layer 6, the convex lens 12 is located at the inner top of the parallel beam layer 6, and the center line of the convex lens 12 passes through the center point of the condensing bevel 11; The light bevel 11 is trapezoidal and the inclination angle of the side of the condensing bevel 11 is 50-75 degrees; the beam adjustment layer 7 includes at least one beam adjustment layer, and the beam adjustment different from the polariz...

Abstract

The invention particularly discloses a mobile phone liquid crystal display screen capable of preventing light leakage. The mobile phone liquid crystal display comprises a frame, a liquid crystal display body and a backlight assembly; the backlight assembly is located on the rear side of the liquid crystal display screen body and fixed in the limiting cavity of the frame; the backlight assembly comprises a parallel light beam layer, a light beam adjusting layer, a polaroid and a light source emitting layer; the parallel light beam layer is located on the rear side of the liquid crystal displayscreen body; the light beam adjusting layer is located on the rear side of the parallel light beam layer; the polaroid is fixed to the rear side of the light beam adjusting layer; and the light sourceemitting layer is fixed to the rear side of the polaroid and fixed to the bottom of the limiting cavity. The mobile phone liquid crystal display screen is reasonable in structure; the backlight assembly is effectively improved; the light source of a light source emitter is continuously reflected multiple times, then the light source is parallelly guided to the liquid crystal display screen body as much as possible, and therefore, the light utilization rate is increased, the light leakage probability is reduced, and energy is saved.

Description

technical field [0001] The invention relates to the field of electronic display screens, in particular to a light-leakage-proof liquid crystal display screen of a mobile phone. Background technique [0002] Mobile phone LCD screen can be divided into: STN screen, TFT screen, TFD screen UFB screen, OLED screen. With the increasing popularity of color screens, the material of mobile phone screens is becoming more and more important. The color screens of mobile phones vary due to different LCD quality and R & D technology, and their types are roughly TFT, TFD, UFB, STN and OLED. Generally speaking, the more colors that can be displayed, the more complex images can be displayed, and the layers of the picture are richer. [0003] However, the utilization rate of the light from the light source in the existing liquid crystal display of the mobile phone is not high, and it is easy to leak out from various gaps of the frame, resulting in halo at the edge position.
