Embodiment 1

[0032] This embodiment provides a light valve.

[0033] The light valve belongs to the field of micro-electromechanical systems (MEMS), that is, it is a very small device, so the display device using the light valve is a MEMS display device.

[0034] Such as Figure 3 to Figure 5 As shown, the light valve of this embodiment includes:

[0035] A substrate 1 having a light-shielding region 11 and a light-transmitting region 12;

[0036] The light filter unit 3 is arranged at a position corresponding to the light-transmitting region 12 of the substrate 1, and includes a light-shielding portion 31 and a conversion portion 32, the light-shielding portion 31 is used to block light from passing through, and the conversion portion 32 is used to convert the transmitted light for the desired color;

[0037] The driving unit 2 is used to drive the filter unit 3 to move so that different parts of the filter unit 3 correspond to the light-transmitting region 12 of the substrate 1 .

Abstract

The invention provides a light valve, a display substrate and a display device, belongs to the technical field of MEMS (micro electro mechanical system) display, and is capable of solving the problems that the existing MEMS display device is complicated in structure, high in cost, short in service life and is not easy to realize. The light valve provided by the invention comprises a base, a filtering unit and a drive unit, wherein the base is provided with a shading area and a light-transmitting area; the filtering unit is arranged at a position which corresponds to the light-transmitting area of the base, and comprises a shading part and a conversion part; the shading part is used for stopping light passing, and the conversion part is used for transmitting light into a required color; the drive unit is used for driving the filtering unit to move so as to enable different parts of the filtering unit to correspond to the light-transmitting area of the base. The display substrate and the display device provided by the invention respectively comprise the light valve.

Description

technical field [0001] The invention belongs to the technical field of micro-electromechanical system display, and in particular relates to a light valve, a display substrate and a display device. Background technique [0002] MEMS (Micro-Electro-Mechanical System, Micro-Electro-Mechanical System) technology refers to the technology of mass-manufacturing tiny devices with specific structures and electromechanical functions, which has been widely used in many fields. [0003] E.g, figure 1 , figure 2 Shown is a light valve using MEMS technology (MEMS light valve), which has a pillar 21 arranged on a substrate 1, the substrate 1 has a light-shielding region 11 and a light-transmitting region 12, and a fixed arm 22 and a moving arm 22 are connected to the pillar 21. The arm 23, the fixed arm 22 and the movable arm 23 are insulated from each other. At the same time, at least a part of the fixed arm 22 and the movable arm 23 are arranged in the same plane and opposite to each ...
