Problems solved by technology

[0002] In existing modules, in order to meet the white point requirements of customers, it is often necessary to select LED color blocks. As a high color gamut LED, fluoride LEDs have a large discrete output, and only a small part of them meet the white point requirements. In order to avoid cost Loss and waste, make full use of all output LEDs, only accept color mixing blocks and mixed brightness proofing assembly
However, for mobile phone modules, in addition to the disadvantages of complex operation and low yield rate, the assembly of mixed color blocks and mixed brightness proofing also has the risk of local spots in the coloring brightness.

Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] refer to figure 1 The chromaticity control light valve of the present invention is used to be arranged under the color filter substrate 1, and a moving grating 3 is arranged under each sub-pixel of the color filter substrate 1, and the corresponding R, R, G, B pixel area, thereby changing the luminous flux of the corresponding pixel, can achieve the balance of display brightness. Specifically, the chromaticity control light valve of this embodiment includes a moving grating 3 and a transparent first electrode 4 and a second electrode 5. The moving grating 3 is electrically connected to t...

Abstract

The invention discloses a chroma regulation and control light valve. The chroma regulation and control light valve comprises moving gratings, a first electrode and second electrodes. Each moving grating comprises two electric connection parts which are insulated from each other and electrically connected with the first electrode and the corresponding second electrode respectively. The moving gratings are arranged below pixels, and the projection areas of the moving gratings on the pixels are selectively changed under driving of the electric field force of the first electrode and the second electrodes so as to regulate the flux of light transmitted to the pixels. The invention further discloses a display panel. The designed novel chroma regulation and control light valve is provided with the moving gratings arranged below the pixels, the positions of the moving gratings can be regulated under driving of the first electrode and the second electrodes, and thus the flux of light transmitted to the pixels can be changed; besides, when the moving gratings are quantum dot gratings, the chroma of a module can be flexibly regulated, and the white dot controllability of the module can be achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a chromaticity control light valve and a display panel. Background technique [0002] In existing modules, in order to meet the white point requirements of customers, it is often necessary to select LED color blocks. As a high color gamut LED, fluoride LEDs have a large discrete output, and only a small part of them meet the white point requirements. In order to avoid cost Loss and waste, making full use of all the LEDs produced, can only accept mixed color blocks and mixed brightness proofing and assembly. But for mobile phone modules, in addition to the disadvantages of complex operation and low yield rate, the assembly of mixed color blocks and mixed brightness samples also has the risk of local spots in the coloring brightness. Contents of the invention [0003] In view of the deficiencies in the prior art, the present invention provides a chromaticity control light valve...
