The analog data voltage of circuit 102a is shifted down;
存储位置2、3对应于源驱动器集成电路102b，在存储位置2处填入数值表示需要控制源驱动器集成电路102b的模拟数据电压向上平移，在存储位置3处填入数值表示需要控制源驱动器集成电路102b的模拟数据电压向下平移；Storage locations 2 and 3 correspond to the source driver integrated circuit 102b. Filling in a value at storage location 2 indicates that the analog data voltage of the source driver integrated circuit 102b needs to be shifted upward, and filling in a value at storage location 3 indicates that it is necessary to control the integration of the source driver. The analog data voltage of circuit 102b is shifted down;

The analog data voltage of circuit 102d is shifted down.
显示装置的各个显示区域中的公共电极电压的电压差为VX，电压差VX通常在0.1～0.2V（伏）范围内，因而，本实施例中，可以将源驱动器集成电路的模拟数据电压Vout的调整范围根据上移或下移的控制来设计成Vout-0.2<Vout<Vout+0.2。The voltage difference of the common electrode voltage in each display area of the display device is VX, and the voltage difference VX is usually in the range of 0.1-0.2V (volts). Therefore, in this embodiment, the analog data voltage Vout of the source driver integrated circuit can be The adjustment range is designed as Vout-0.2<Vout<Vout+0.2 according to the control of moving up or down.
此外，对源驱动器集成电路的模拟数据电压Vout的调整的精度可以由时序控制器中的暂存器的位数决定，上述表格中所示的暂存器的位数为8，则对模拟数据电压Vout的调整具有28（256）阶，即对模拟数据电压Vout每调整一阶的数值为±0.2/256V。In addition, the accuracy of adjusting the analog data voltage Vout of the source driver integrated circuit can be determined by the number of bits of the temporary register in the timing controller. The number of bits of the temporary register shown in the above table is 8, and the analog data The adjustment of the voltage Vout has 28 (256) steps, that is, the value of each step of adjusting the analog data voltage Vout is ±0.2/256V.
举例来说，假设以显示区域103a的VCOM为基准公共电极电压，显示区域103a的VCOM为5V。检测到显示区域103b的VCOM为4.96V，则显示区域103b的VCOM与基准公共电极电压的电压差为0.04V。For example, assume that the VCOM of the display region 103a is used as the reference common electrode voltage, and the VCOM of the display region 103a is 5V. It is detected that the VCOM of the display area 103b is 4.96V, and the voltage difference between the VCOM of the display area 103b and the reference common electrode voltage is 0.04V.
假设暂存器的位数为2，则对模拟数据电压Vout的调整具有22阶，则有0.2V/22阶=0.05V，即对模拟数据电压Vout每调整一阶的数值为±0.05V，具体的，可以采用（0，0）表示电压差为0，采用（0，1）表示电压差为0.05，采用（1，0）表示电压差为0.1，采用（1，1）表示电压差为0.15。Assuming that the number of bits in the temporary register is 2, the adjustment of the analog data voltage Vout has 22 steps, then there is 0.2V/22 steps = 0.05V, that is, the value of each step of adjusting the analog data voltage Vout is ±0.05 V, specifically, (0, 0) can be used to indicate that the voltage difference is 0, (0, 1) can be used to indicate that the voltage difference is 0.05, (1, 0) can be used to indicate that the voltage difference is 0.1, and (1, 1) can be used to indicate the voltage The difference is 0.15.
此时，时序控制器101可以通过暂存器的位置存储位置0或1向源驱动器集成电路102a输出数值为（0，0），表示不需要平移源驱动器集成电路102a的模拟数据电压；可以通过暂存器的位置存储位置2可以向源驱动器集成电路102b输出数值为（0，1），表示需要将源驱动器集成电路102b的模拟数据电压向上平移一阶（0.05V）。At this time, the timing controller 101 can output a value of (0, 0) to the source driver integrated circuit 102a through the storage position 0 or 1 of the temporary register, indicating that the analog data voltage of the source driver integrated circuit 102a does not need to be shifted; The storage position 2 of the temporary register can output a value of (0, 1) to the source driver integrated circuit 102b, indicating that the analog data voltage of the source driver integrated circuit 102b needs to be shifted up by one step (0.05V).
