A display panel includes a transparent substrate and a light emitting function layer and a color resist layer formed on the transparent substrate. The transparent substrate has a light emitting region and a non-light emitting region. The light-emitting functional layer is located at a side of the transparent substrate and includes a transistor and an organic light emitting device. The transistor is formed on the non-light-emitting region. The color resist layer is located on a side of the transparent substrate away from the light-emitting function layer. The color resist layer includes a black matrix formed on the non-light-emitting region and a color filter formed on the light-emitting region. Light emitted by the organic light-emitting device is emitted through the light-emitting region of the transparent substrate and the color filter in sequence.

A display driving circuit includes a driving transistor, a storage circuit, a first reset circuit, a data writing circuit, a compensation circuit and a light-emitting control circuit. The first and second light-emitting control circuits, the driving transistor and the display light-emitting circuit are connected in sequence. The storage circuit is connected to a control terminal of the driving transistor and power supply high voltage terminal, the first reset circuit is connected to the control terminal of the driving transistor, the data writing circuit is connected to a first terminal of the driving transistor, the compensation circuit is connected to the control terminal and a second terminal of the driving transistor, the first and second light-emitting control circuits are used to switch on the power supply high voltage terminal and the display light-emitting circuit in response to first and second scan signals.

Display driving circuit, display driving method and display panel

Disclosed is a method of compensating for a color shift of a display panel, a display module, and an electronic device, in which the method includes: in the case where a color shift occurs in a white screen of the display panel, determining a position where the color shift occurs; changing a timing of sub-pixels lighting the white screen in the position to a timing of red, green and blue pixels; adjusting brightness of the red pixel, brightness of the green pixel and brightness of the blue pixel to compensate for the color shift in the position. The present disclosure solves the technical problem that a color shift repairing technology in the related art can only solve unevenness of brightness within a certain range, resulting in poor repairing effect of the display panel.

Display module, electronic device and method of compensating for color shift of display panel

A display panel and a display device are provided. The display panel includes a display region and a non-display region surrounding the display region. The non-display region is provided with multiple sensing components. The multiple sensing components each are configured to generate a first signal when the display panel is in a flattened state. When the display panel is in a partially-rolled state, the display panel includes a flattened part and a rolled part, a sensing component in the flattened part is configured to generate the first signal, and a sensing component in the rolled part is configured to generate a second signal. The multiple sensing components each are configured to generate the second signal when the display panel is in a fully-rolled state.
