A display device and an OLED display panel thereof. The OLED display panel includes a non-transparent display area including first OLED pixels, a transparent display area including second OLED pixels, a display driving chip, a first gate driving circuit group. For a same of image, a pulse width of the second gate driving signal for the second OLED pixels is substantially the same as a pulse width of the first gate driving signal for the first OLED pixels; and intersection points of a boundary line and a pixel row where the first OLED pixels in a specified row are located falls within a range of intersection points of the boundary line and a corresponding pixel row of the second OLED pixels.

Display device and OLED display panel thereof

Provided are a display panel and a display device. The display panel includes a substrate; multiple light emitting units which is disposed on one side of the substrate and arranged in an array, and each of the multiple light emitting unit includes a first light emitting subunit, a second light emitting subunit and a third light emitting subunit, where the light emitting unit includes a first electrode disposed close to the substrate, a second electrode disposed opposite to the first electrode, and a second light emitting layer disposed between the first electrode and the second electrode, at least the third light emitting subunit includes at least one first light emitting layer disposed between the second light emitting layer and the first electrode.

Display panel and display device

The exemplary embodiments of the present application provide a drive circuit for a display panel having a slot, a display screen and a display device. The drive circuit includes: a first drive line, for regulating luminous brightness of pixels in a row or column where the slot is located, and/or for regulating luminous brightness of pixels in a row or column adjacent to the slot; and a second drive line, for regulating luminous brightness of pixels in a row other than the row regulated by the first drive line, or for regulating luminous brightness of pixels in a column other than the column regulated by the first drive line; wherein, the currents or voltages applied to the first drive line and the second drive line are different.

Drive circuit for a display panel having a slot, display screen and display device

Exemplary embodiments of the application disclose pixel circuits and driving methods thereof, display devices. A pixel circuit includes a first through seventh thin film transistors, a light-emitting diode, and a storage capacitance. The pixel circuit provided by exemplary embodiments of the application can compensate a power voltage during a light-emitting stage of the light-emitting diode, so that the current flowing through the LED is related to a data voltage and a reference voltage input into the pixel circuit, and is independent of the power voltage, thereby effectively avoiding the problem of the display unevenness of the display device, due to the difference in the current flowing into the LED caused by the power voltage drop.

Pixel circuits and driving methods thereof, display devices

The disclosure discloses a pixel circuit and a driving method thereof, a display device. The pixel circuit includes a first through six thin film transistors, a light-emitting diode and a storage capacitor. A gate of the first thin film transistor is separately connected to a source of the second thin film transistor, a source of the third thin film transistor and one end of the storage capacitor. The other end of the storage capacitor is separately connected to a drain of the fourth thin film transistor and a source of the fifth thin film transistor. A source of the first thin film transistor is connected to a first power source. A drain of the first thin film transistor is separately connected to a drain of the second thin film transistor and a source of the sixth thin film transistor.
