Title: DISPLAY DEVICE AND FILTER THEREOF
Abstract:
A display device and a filter (1) thereof. The filter (1) comprises a dielectric layer (11) and a wire gating structure array arranged on the dielectric layer (11); each wire gating structure (12a) comprises a first wire gating unit (120), a second wire gating unit (121), a third wire gating unit (122) and a fourth wire gating unit (123); the first wire gating unit (120), the second wire gating unit (121), the third wire gating unit (122) and the fourth wire gating unit (123) respectively comprise a plurality of wire gatings 100 arranged at intervals; the gating distances of the first wire gating unit (120), the second wire gating unit (121), the third wire gating unit (122) and the fourth wire gating unit (123) are not equal; and the first wire gating unit (120), the second wire gating unit (121), the third wire gating unit (122) and the fourth wire gating unit (123) are used for respectively filtering incident light to obtain four different colours of light. By means of the display device and the filter (1), a coordinate of white light synthesized by an R sub-pixel, a G sub-pixel and a B sub-pixel can match a coordinate of white light of a W sub-pixel.
