A bezel-less display panel, a display device, and a spliced display device are disclosed. The bezel-less display panel includes a first display area, a second display area around the first display area, and a third display area around the second display area. The third display area is not provided with a subpixel driving thin-film transistor. Some of driving thin-film transistors in the second display area are connected to light-emitting subpixels in the third display area through a plurality of metal lines.

Bezel-less display panel, display device, and splice-type display device

The present application provides a display device. The display device includes a pixel circuit and multiple operational amplifiers. Pixel units in the same column are electrically connected to the same operational amplifier. The display device of the present application uses the operational amplifier to stabilize a voltage and amplify a current, which solves non-uniformity of the display panel caused by the difference in a threshold voltage and channel electron mobility of the thin film transistor due to an immature manufacturing process of a thin film transistor, so uniformity of the panel is improved.

Display panel

The present invention provides a display panel, a control method thereof, and an electronic device. The display panel include a control module corresponding to a display region. The control module is connected to a gate driving unit in the corresponding display region and pixel driving module corresponding to the gate driving unit. The control modules is configured to control the gate driving unit in the corresponding display region to connect or disconnect with the corresponding pixel driving module according to a control signal.
