  • Application method of demura data having uniform format
    Patent number: 10950195
    Abstract: An application method of demura data having a uniform format includes: in step S12, it is determined whether demura data having a first format is stored in a first memory; if yes, step S13 is performed; if no, step S16 is performed; in step S13, it is checked whether the demura data having the first format is consistent with demura data having a second format and stored in a second memory; if yes, step S14 is performed; if no, step S16 is performed; in step S14, the demura data having the first format in the first memory is read; in step S15, a demura data compensation is activated; and in step S16, demura data having the first format is generated, according to the demura data having the second format and stored in the second memory, and stored; step S15 is performed.

  • TIMING CONTROL BOARD AND DISPLAY DEVICE
    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.
