  • Publication number: 20210082358
    Abstract: The present invention teaches a white balance method and device for a LCD panel. The method includes the following steps. Step S1 provides a LCD panel, including a mask-joint area and a non-mask-joint area outside the mask-joint area. The mask-joint area includes multiple first color resists arranged in an array, and the non-mask-joint area includes multiple second color resists arranged in an array. The first and second color resists are of different dimensions. Step S2 obtains a first white balance driving table for the mask-joint area and a second white balance driving table for the non-mask-joint area. Step S3 conducts white balance to the mask-joint area and non-mask-joint area using the first and second white balance driving tables, respectively. By applying different white balance driving tables to the mask-joint area and the non-mask-joint area, the white balance effect is improved, and the display quality of the LCD panel is enhanced.

  • Publication number: 20210082357
    Abstract: The present invention teaches a method for removing backlight mura. The method divides backlight into partitions, and divides each partition into units. The method then selects one of the partitions as a reference partition and selects the compensation values of the reference partition from all partitions. The method further calculates brightness difference values for all partitions other than the reference partition relative to the brightness of the reference partition. Finally, the method conduct brightness compensation to the other partitions based on the reference partition's compensation values, and the brightness difference values of the other partitions. The method may not only effectively eliminate backlight mura, but also allow the direct-lit backlight module to be thinner or of lower cost, and significant reduce storage requirement and logic resource.

  • Publication number: 20210043157
    Abstract: A timing control (TCON) board and a display device are provided. The TCON board includes a TCON chip and a CB. A plurality of heat dissipating terminals are provided to commonly connect the TCON chip to the CB, increasing a total contact area of the TCON board and the CB. Therefore, heat dissipation efficiency of the TCON chip is improved. At the same time, the heat dissipating terminals greatly reduce a pseudo connection percentage. Hence, heat dissipation performance and electrical performance of the entire TCON chip are avoided to be impacted.
