  • Patent number: 12354534
    Abstract: The driving device includes a starting-position adjustment circuit and a pulse-width modulation (PWM) circuit. The starting-position adjustment circuit shifts a PWM counting value according to a starting-position setting to generate an adjusted counting value of a first channel. The starting-position setting is configured to indicate which subframe period in a same display frame period a starting value of the adjusted counting value is located in. The PWM circuit compares grayscale data of the first channel with the adjusted counting value and generates a PWM signal of the first channel according to a comparison result.

  • Patent number: 11929007
    Abstract: A display driving integrated circuit (IC) and a driving parameter adjustment method thereof are provided. The display driving IC includes a control circuit and a driving parameter determination circuit. The control circuit controls a current driving circuit and a scanning circuit according to a driving parameter, wherein the current driving circuit is suitable for driving multiple driving lines of a light emitting diode (LED) array, and the scanning circuit is suitable for driving multiple scanning lines of the LED array. The driving parameter determination circuit is coupled to the control circuit to provide the driving parameter. The driving parameter determination circuit dynamically adjusts the driving parameter for a target LED in the LED array according to a grayscale value of the target LED.
