Abstract: Disclosed are a display device and a method for operating pixels of the display device. The display device comprises: a light-emitting element; and a pixel circuit configured to control the light-emitting element, wherein the pixel circuit includes: a capacitor connected to and disposed between a first node and a second node; and a driving transistor including a gate electrode connected to the second node; a first electrode receiving a high-potential driving voltage; and a second electrode connected to a third node, wherein the pixel circuit is configured such that the same voltage is supplied to the first node and the second node during at least a portion of an operation period of the pixel circuit. Thus, occurrence of a reference voltage related short-circuit in the light-emitting element of the pixel circuit is suppressed to prevent occurrence of defective image display in each pixel and to improve reliability thereof.

Abstract: A display device includes a light-emitting element; a capacitor connected to and disposed between a first node and a second node; a first transistor including a first electrode connected to a reference voltage supply line and a second electrode connected to the first node, and supplying a reference voltage to the first node in response to a light-emission control signal of an n-th pixel row; a second transistor including a first electrode connected to the reference voltage supply line and a second electrode connected to the second node, and supplying the reference voltage to the second node in response to a first scan signal of an (n−1)-th pixel row; and a driving transistor including a gate electrode connected to the second node, a first electrode receiving a high-potential driving voltage, and a second electrode connected to a third node. Thus, for example, occurrence of a reference voltage related short-circuit in the light-emitting element of the display device is suppressed to prevent occurrence of defective image display in each pixel and to improve reliability thereof.

Abstract: A display device and a method for driving the same are discussed. The display device includes an image processing unit, a timing controller which receives various signals through a mobile industry processor interface (MIPI) connected to the image processing unit, and a display module displaying an image under the control of the timing controller. The timing controller includes a logic block for controlling the display module, and a self-recovery block which outputs a self-command signal for escaping an abnormal state when the logic block is faced with the abnormal state due to an external environment factor.
