Abstract: The present application provides an electronic device, which includes a display unit, a display driving circuit, and an electronic component. The display driving circuit is coupled to the display unit, and the display driving circuit is capable of driving the display unit to display images with a plurality of refresh rate modes including a first refresh rate and a second refresh rate. The electronic component is disposed under a display area of the display unit, is coupled to the display driving circuit, and receives a dynamic refresh signal generated by the display driving circuit, wherein the dynamic refresh signal includes a plurality of initial pulses and a plurality of delay pulses. Thus, the present application overcomes the problem that mutual interference between display pixels and under-screen electronic component cannot be effectively avoided in existing technology when the display unit changes screen refresh rates.

Abstract: The present application relates to a display system with a light sensor and a control method thereof. The display system comprises a display module and a light sensor. The display module comprises a driving circuit for generating a driving signal. Said driving signal comprises a plurality of periodic pulse waves. The OFF time of one of the periodic pulse waves is extended to an extended time which is greater than the OFF time of the remaining periodic pulse waves. This ensures that the sensing result of the light sensor may not include the contribution of display light.

Abstract: The present invention relates to a driving method for flicker suppression of a display panel and a driving circuit thereof. The driving circuit includes a source driving circuit and a common voltage generating circuit. The driving method includes driving the source driving circuit to generate at least one first source signal and at least one second source signal, the first source signal corresponds to at least one first pixel on a first scanning line; the second source signal corresponds to at least one second pixel on a second scanning line. The common voltage generating circuit generates at least one common voltage. While driving the first pixel and the second pixel to display the same gray scale image, the first source signal is not equal to the second source signal, or a first common voltage and a second common voltage generated by the common voltage generating circuit are different.
