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 .
