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.

Method and device for controlling timing sequence, drive circuit, display panel, and electronic apparatus

The present disclosure relates to a backlight module and a display device. The backlight module comprises a light guide plate and a light-emitting assembly configured to emit light rays and cause the light rays as emitted to be incident to the light guide plate in parallel. The light guide plate further comprises a light incident surface, a bottom surface, a light emitting surface on the top thereof, and at least one reflective sloped surface. The reflective sloped surface is positioned between the bottom surface and the light emitting surface, and an angle between the at least one reflective sloped surface and a plane of the bottom surface extending in a direction away from the light incident surface is less than 90&#xb0;. The light incident surface is located on a side of the light guide plate.

Backlight module and display device

A display panel is provided including: an array substrate; a plurality of gate scanning signal lines and a plurality of data signal lines on the array substrate, projections of the plurality of gate scanning signal lines on the array substrate and projections of the plurality of data signal lines on the array substrate intersecting with each other; a plurality of sub-pixels arranged in an array, the plurality of sub-pixels being surrounded by the plurality of gate scanning signal lines and the plurality of data signal lines; touch sensing signal lines; and touch circuits. At least a part of the gate scanning signal lines are multiplexed to charge the touch circuits, and each of the touch sensing signal lines is configured to sense a change in an electrical signal of one of the touch circuits which have been charged so as to determine a position of a touch point.

Display panel including touch circuit, touch detection method thereof and display device

The present disclosure provides a tunable backlight device, a display device and method of driving the display device. The tunable backlight device comprises: at least one backlight apparatus with high color gamut and low luminance; at least one backlight apparatus with low color gamut and high luminance; a storage configured to store a library of current feedback coefficients; a current feedback apparatus, configured to determine a first current feedback coefficient (K) for the backlight apparatus with high color gamut and low luminance and a second current feedback coefficient (K) for the backlight apparatus with low color gamut and high luminance, according to the requirements, respectively; a backlight driving apparatus configured to supply respective currents to both the backlight apparatuses to emit lights, based on the first and the second current feedback coefficients, respectively; and a light guide plate configured to mix the lights emitted from the both backlight apparatuses.
