摘要： A backlight module suitable for thermal coupling with a display panel includes a light guide plate which has a light incident surface and a light exiting surface, a light source configured such that light emitted therefrom enters the light guide plate from the light incident surface and exits the light guide plate from the light exiting surface to irradiate onto the display panel, a heat sink configured to partially accommodate the light guide plate and the light source, and a heat conducting device disposed between the heat sink and the display panel to conduct heat generated from the display panel to the heat sink. The backlight module can quickly dissipate heat generated from a heat concentrated area of the display panel to the outside.

摘要： Embodiments of the present disclosure provide a method and a device for controlling a timing sequence, a drive circuit, a display panel, and an electronic apparatus. In this method, a frame scan timing sequence for a display signal may be set according to a frame rate of the display signal, wherein the frame scan timing sequence includes an active period and a blanking period. The frame scan timing sequence may be arranged to increase the active period as the frame rate of the display signal decreases.

摘要： A display device, a pixel circuit and its driving method and driving device. The driving method includes the steps of, during a frame sequence formed by successive X frames of image displaying, outputting gate signals and data signals to the pixel circuit in a first preset mode; during a frame sequence formed by successive Y frames and adjacent to the frame sequence formed by successive X frames of image displaying, outputting gate signals and data signals to the pixel circuit in a second preset mode, wherein the first preset mode is different from the second preset mode, and X and Y are positive integers not less than 2. The method can enable the charging time of the pixel circuit to be balanced in space, thereby improving image display quality.

摘要： A touch display device and a driving method thereof are provided. A driving signal line configured to drive light emitting unit to emit light is multiplexed as a detection electrode. Moreover, the capacitance is formed between the detection electrode and a transparent conductive layer, the capacitance can be changed according to a change in touch force, so that when a position of the detection electrode is pressed, a distance between the detection electrode and the transparent conductive layer changes, and the capacitance between the detection electrode and the transparent conductive layer changes accordingly. In this way, a magnitude of the force at a touch position can be determined by a change in a capacitance value between the detection electrode and the transparent conductive layer, so that a force touch function can be realized.
