Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal modules, in particular to a color spot removing shading plate. Background Art

[0002] In the existing liquid crystal module, the backlight source of the semi-transmissive and semi-reflective screen uses dual-color temperature LEDs, one for white light and the other for yellow light. According to the usual LED layout design, the number of LEDs is an even number. In order to facilitate the mixing of dual-color temperature LEDs, the dual-color temperature LEDs are arranged alternately, which will cause the LEDs at both ends of the module to be LEDs of different color temperatures, resulting in display color spots.

[0003] Since the color temperatures of the LEDs at the two corners are different, not only the colors are different, but also the brightness is quite different. It is difficult to adjust the light mixing at the corners, and it is basically impossible to overcome this color spot by light mixing adjustment alone. Utility Model Content

[0004] The purpose of the utility model is to provide a color spot removing shading plate, which changes a traditional 2in1 white light LED into two 1in1 white light LEDs, so that the two corners are simultaneously changed into 1in1 white light LEDs, which is not only convenient for mixed light adjustment, but also can eliminate the obvious brightness and color difference of the two corners. The driving requirements of the two 1in1 white light LEDs and one 2in1 white light LED are the same, so only the LED connection wiring needs to be adjusted, and the driving circuit can remain unchanged, thereby eliminating the color spots at the corners of the liquid crystal module.

[0005] To achieve the above-mentioned purpose, a color spot removing shading plate is provided, comprising: an LED arrangement group and an LED circuit group, the LED arrangement group comprising a first LED lamp, a second LED lamp and a third LED lamp, the number of the first LED lamps is set to two, and they are symmetrically distributed at the left and right ends, the number of the second LED lamps and the third LED lamps is set to multiple, and they are evenly staggered and distributed between the two first LED lamps; the LED circuit group comprises a first circuit, a second circuit, a third circuit, a fourth circuit, a fifth circuit and a sixth circuit, the first circuit, the second circuit, the third circuit, the fourth circuit, the fifth circuit and the sixth circuit are arranged in sequence from left to right, the number of the first circuit, the second circuit, the third circuit, the fourth circuit, the fifth circuit and the sixth circuit are all set to multiple, and they are evenly distributed in a cycle, and the first circuit is arranged at the left and right ends.

[0006] According to the color spot removing shading plate, the first LED lamp is a 1in1 white light LED lamp, the second LED lamp is a 2in1 white light LED lamp, and the third LED lamp is a 2in1 yellow light LED lamp.

[0007] According to the color spot removing shading plate, the first circuit is white light LEDx4pcs+1in1x2pcs.

[0008] According to the color spot removing shading plate, the second circuit, the fourth circuit and the sixth circuit are all yellow light LED x 5pcs.

[0009] According to the color spot removing shading plate, the third circuit and the fifth circuit are both white light LEDx5pcs.

[0010] According to the color spot removing shading plate, the first LED lamp, the second LED lamp and the third LED lamp are respectively arranged in a one-to-one correspondence with the first circuit, the second circuit, the third circuit, the fourth circuit, the fifth circuit and the sixth circuit.
