The present application discloses a driving circuit, a driving method, and a display panel. The driving circuit includes: a plurality of pixels, each pixel including a first sub-pixel and a second sub-pixel; and a switching circuit, configured to communicate one or both of the first sub-pixel and the second sub-pixel with a scan line and a data line.

A method of driving a display panel that includes first and second display-regions includes: determining maximum luminance data among first data including first red data, first green data, and first blue data for the first display-region, calculating a threshold gray-level based on a luminance gain, a gray-level of the maximum luminance data, and a gamma value for the display panel, selecting a smaller value between the threshold gray-level and a maximum gray-level as a gain determination gray-level, calculating a compensation gain obtained by dividing the gain determination gray-level by the gray-level of the maximum luminance data, generating first compensated data by applying the compensation gain to the first data, displaying a first-image in the first display-region based on the first compensated data, and displaying a second-image in the second display-region based on second data including second red data, second green data, and second blue data for the second display-region.

Exemplary methods, apparatuses, and systems generate an object in a portion of an electronic display. The object is generated as a shape formed by a pattern of a first plurality of pixels being illuminated for a first sequence of frames and a second plurality of pixels not being illuminated for the first sequence of frames. During the first sequence of frames, each set of illuminated pixels from the first plurality of pixels is separated from another set of illuminated pixels by a set of non-illuminated pixels of the second plurality of pixels. In response to an event, the object in the portion of the electronic display is generated by illuminating pixels of the second plurality of pixels for a second sequence of frames and not illuminating pixels within the first plurality of pixels for the second sequence of frames.

An electronic device may include an electronic display including display pixels to display an image based on compensated image data. The electronic display may also include a stressed reference pixel to exhibit burn-in related aging in response to one or more stress sessions and a non-stressed reference pixel configured to not undergo the one or more stress sessions. Additionally, the electronic device may include image processing circuitry to determine a panel-specific aging profile based on a comparison between one or more properties of the stressed reference pixel and the one or more properties of the non-stressed reference pixel. The image processing circuitry may also generate one or more gain maps based on the panel-specific aging profile and generate the compensated image data by applying the one or more gain maps to input image data.

A light-emitting drive circuit, a driving method thereof, and a display panel are provided. In the light-emitting drive circuit, a first end of the storage capacitor is connected to a first electrode of the first transistor, a control electrode of the drive transistor, and a second electrode of the second transistor, and a second end of the storage capacitor is connected to a second electrode of the first transistor and a second electrode of the drive transistor. A control electrode of the first transistor is connected to the control line.

A display apparatus is provided, which includes a display panel and a display controller. The display controller calculates an image average brightness of each image in a video signal from a host. When an absolute difference between a first image average brightness of a current image and a second image average brightness of a previous image is smaller than a predetermined value, the display controller activates a timer to obtain a timer value. When the timer value reaches a first duration, the display controller reduces brightness of each pixel in the current image by a first ratio. When the timer value reaches a second duration, the display controller reduces the brightness of each pixel in the current image by a second ratio. The second duration is longer than the first duration, and the second ratio is higher than the first ratio.

A display device that can compensate for degradation of circuit elements while suppressing an increase in circuit size is implemented. A data signal line (S(j)) is not only used as a signal line that transfers a signal for allowing an organic EL element (OLED) in each pixel circuit (11) to emit light at a desired luminance, but also used as a signal line for characteristic detection. In addition, a switch (334) is provided between the data signal line (S(j)) and an internal data line (Sin(j)). In such a configuration, during an AD conversion period during which analog data obtained for characteristic detection is converted into digital data, the switch (334) is brought into an off state and a potential of the data signal line (S(j)) obtained immediately before the AD conversion period is supplied from through a predetermined control line (CL) to the data signal line (S(j)).

An afterimage compensator and a display device having the same are disclosed, and the afterimage compensator includes an image analyzer configured to determine an amount of image variation based on a change of image data, and an image shifter configured to adjust a shift interval, which is an interval between time points at which an image is shifted, according to the amount of image variation.

A display substrate and a display device. The display substrate includes a pixel circuit in which the driving circuit controls a driving current for driving the light emitter element to emit light; the first light emission control circuit applies a first voltage to a first terminal of the driving circuit in response to a first light emission control signal; the second light emission control circuit applies the driving current to the light emitter element in response to a second light emission control signal; the first reset circuit applies a first reset voltage to the control terminal of the driving circuit in response to a first reset signal; the first reset signal and the first light emission control signal are simultaneously turn-on signals during a period; the first light emission control line and the second light emission control line extend along a first direction and are arranged in a second direction.

The logo controller generates a first logo map based on an input image signal of a previous frame, generates a second logo map based on an input image signal of a current frame, and determines a similarity between the first logo map and the second logo map to selectively change luminance of a logo image of a next frame.
