  • Publication number: 20240105136
    Abstract: An electronic device includes a display unit, a voltage generation unit, a grayscale adjustment unit, and an overdriving unit. The display unit has a relationship curve between the transmittance and the driving voltage. The relationship curve has a predetermined voltage value corresponding to the maximum transmittance. The voltage generation unit generates a first voltage according to a first grayscale, and generates a second voltage according to a second grayscale. The grayscale adjustment unit receives a first display grayscale value, and outputs the second grayscale value when the first display grayscale value is equal to the first grayscale. The overdriving unit overdrives the second voltage corresponding to the second grayscale to obtain a first target driving voltage, and it provides the first target driving voltage to the display unit.

  • Publication number: 20240021170
    Abstract: An electronic device includes gate lines, maintained at a low level voltage during a blank period and sequentially scanned during an active period in a frame period, and data lines. Voltage polarities of the data lines for all the blank period are respectively identical with voltage polarities of the data lines during the active period. A first level voltage applied to one of the data lines during all the blank period is related to an average value or a maximum value of level voltages of a portion or all of the data lines during the active period. A time length of the blank period in the frame period with the average value or the maximum value applied to one of the data lines during all the blank period is longer than a first time length of a first blank period in a first frame period adjacent to the frame period.
