Embodiment Construction

[0032] The implementation process of the embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] An embodiment of the present invention is an optical device, such as figure 1 with figure 2 As shown, it includes an optical structure 1 and a control component 2;

[0034] The optical structure includes a first triangular prism group 11 and a second triangular prism group 12, and the refractive indices of the two triangular prism groups are equal;

[0035] The control part 2 connects the second triangular prism group 12, or the control part 2 connects the first triangular prism group 11 and the second triangular prism group 12; the control part 2 is used to make the second triangular prism group 12 Separate or engage with the first triangular prism group 11.

[0036] in, figure 1 It is a schematic diagram when the first triangular prism group 11 and the second triangular prism group 12 are engaged, figure...

Abstract

The invention discloses an optical device, and a control method and a display device thereof. The optical device comprises an optical structure and a control component, wherein the optical structure comprises a first triple prism set and a second triple prism set, refractive indexes of the two triple prism sets are equal; the control component is connected with the second triple prism set or connected with the first triple prism set and the second triple prism set; and the control component is used for separation or occlusion of the second triple prism set and the first triple prism set through mechanical movements. The optical device is provided with the two triple prism sets, and can be switched between transmission and total reflection by enabling the two triple prism sets to occlude or separate, and therefore the utilization rate of optical energy is improved. In addition, by arranging the optical device between a lower base plate and a lower polarizer of a liquid crystal display panel, switching of a transmission mode and a reflection mode is achieved, the utilization rate of a pixel is improved, and complexity of manufacture is reduced without changing a pixel structure.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an optical device, a control method thereof, and a display device. Background technique [0002] Liquid crystal displays are classified into transmissive displays, reflective displays, and transflective displays. [0003] There is no reflective mirror on the back of the transmissive display screen, and the light source is provided by the backlight, which is excellent in low light or no light. However, the brightness of the backlight is seriously insufficient in outdoor sunlight or in a strong light environment, and simply relying on increasing the brightness of the backlight will rapidly lose power, and the effect is also very unsatisfactory. [0004] Reflective displays have a reflector on the back of the screen and rely on external light sources to achieve the display effect. Therefore, it will show better effects and contrast outdoors and under strong light. However, it is d...
