An organic light-emitting diode (OLED) display screen includes: a first area provided with a plurality of first light-emitting components; a second area provided with a plurality of second light-emitting components; and a driving element group electrically connected to the first light-emitting components and the second light-emitting components to drive the first light-emitting components and the second light-emitting components to emit light; wherein the driving element group is disposed on an area other than the second area on the display screen and disposed at least in the first area.

Organic light-emitting diode display, display control method and electronic device

The present disclosure relates to a display structure, a display panel, and a display device. The display structure includes: a plurality of pixels and a plurality of first driving circuits. The plurality of pixels are provided in a first area of the display structure. The plurality of pixels are arranged based on a preset pattern. An area of the preset pattern is less than that of the first area. Each pixel includes sub-pixels of a plurality of colors, and each sub-pixel includes an organic light emitting diode. The plurality of first driving circuits are provided in a second area outside the first area, connected to the organic light emitting diodes, and configured to drive the organic light emitting diodes to emit light.

Display structure, display panel and display device

An organic light-emitting diode (OLED) display screen and an electronic device are provided. The OLED display screen includes, in a first direction, a first region and a second region. A first film layer in the first region of the display screen is provided with one or more driving elements, and the first film layer in the second region of the display screen is provided with no driving element. One or more first light-emitting elements arranged in the first region and one or more second light-emitting elements arranged in the second region are driven by the one or more driving elements in the first region.

Organic light-emitting diode display screen and electronic device

Embodiments of the disclosure provide a display driving device including: a counting unit configured to count the number of first pixel points whose gray level values are larger than or equal to a first gray level value and the number of the other pixel points whose gray level values are smaller than the first gray level value in an image displayed by a target display, a comparing unit configured to compare the number of the first pixel points and the number of the other pixel points and transmit a first instruction to the driving unit if the former is larger than or equal to the latter, and a driving unit configured to control a refresh frequency of the display to be larger than or equal to a first frequency if the first instruction is received, otherwise, control the refresh frequency of the display to be smaller than the first frequency.

Controlling a refresh frequency for a display driving device and methods of operation thereof

The present invention discloses a backlight, a regulation method thereof, a regulation device and a display device. The backlight comprises a driving unit, a register, a PWM unit and a light-emitting unit, the PWM unit is connected between the driving unit and the light-emitting unit, and the register is connected to the PWM unit. The driving unit is used for converting a voltage signal to a primary driving signal; the register is used for defining a preset threshold value, which is the maximum value of duty ratio of a signal that the PWM unit outputs when performing a PWM process; the PWM unit is used for regulating duty ratio of the primary driving signal according to the preset threshold value and generating a regulated driving signal; and the light-emitting unit is used for emitting light when being driven by the regulated driving signal.
