In an embodiment according to the present disclosure, disclosed is an electronic device including a display, a first housing, a second housing at least partially overlapping and being movable with respect to the first housing, a first conductive region formed or disposed inside the first housing, and a second conductive region formed or disposed inside the second housing so as to at least partially overlap with the first conductive region when the first housing is moved with respect to the first housing, a display in which at least the first region is exposed to the outside of an electronic device through a front surface of the electronic device, and at least one processor in which, when the electronic device is switched from the first state to the second state, a second region extending from the first region of the display is withdrawn from the inside of the first housing and exposed to the outside of the electronic device along with the first region and, when the electronic device is switched from the second state to the first state, is introduced into the inside of the first housing and operatively connected to the display. The at least one processor identifies a capacitance value, based on an overlapped region of the first conductive region and the second conductive region, and determines an externally exposed region of the display, based on the identified capacitance value, and controls the region determined to be exposed outside, to an activated state, and controls the remaining region except the region determined to be exposed outside, to an inactivated state. In addition to this, various embodiments identified through the specification are possible.

A display apparatus having a wide range of threshold voltage compensation function is provided. In the display apparatus, a p-channel transistor is used as a driving transistor of the light-emitting device. Discharging is performed through a source-drain path while constant voltage is supplied to a gate so that Vth is extracted between the gate and the source. In addition, when a drain potential is set to the sum of forward voltage and a cathode potential of the light-emitting device or a potential sufficiently lower than the sum, it is possible to continue the discharging even when Vth is positive voltage. That is, compensation can be performed even in the case where Vth variation occurs from positive voltage to negative voltage.

A system and method are described for creation of a mosaic display system. A device is assigned an address which may be used to produce unique sequence of illumination which is based on a code determined by the address. A sequence of images of a number of devices may be used to determine a spatial location associated with a device address.

A display device comprises a substrate; a circuit array layer comprising pixel drivers, data lines, first dummy lines, and second dummy lines; and a light emitting array layer. The display area comprises middle, first side, and second side regions. The data lines comprise first, second, and third data lines disposed in the middle, first side, and second side regions, respectively. The first dummy lines comprise a first data detour line disposed in the first side region and adjacent to a part of the second data line, and auxiliary lines. The second dummy lines comprise a second data detour line configured to connect the first data detour line to the third data line, and additional lines. The auxiliary lines comprise a bias auxiliary line to which a bias power is applied; and a second power auxiliary line to which a second power is applied.

A method for addressing a bistable electro-optic display having at least one pixel comprises applying an addressing pulse to drive the pixel to a first optical state; leaving the pixel undriven for a period of time, thereby permitting the pixel to assume a second optical state different from the first optical state; and applying to the pixel a refresh pulse which substantially restores the pixel to the first optical state, the refresh pulse being short relative to the addressing pulse.

Video displays using relatively low frame rates of about 10 to about 20 frames per second, but having acceptable video quality are described. The displays may use bistable media, and may be driven such that the medium, when driven, changes its optical properties continuously during the driving of each frame. The displays may use an electro-optic medium such that the frame period is from about 50 to about 200 per cent of the switching time of the electro-optic medium at the driving voltage used.

A pixel includes a light emitting element, a first transistor having a first electrode connected to a first power line via a first node, a second electrode connected to a second power line via a second node and the light emitting element, and a gate electrode connected to a third node, a second transistor connected between a data line and the third node, and having a gate electrode connected to a first scan line, a third transistor connected between the first power line and the first node, and having a gate electrode connected to an emission control line, and a fourth transistor connected between the second node and a third power line. The second transistor is turned on after the fourth transistor is turned on and maintains a turn-on state during a predetermined period, and is turned off before the fourth transistor is turned off.

A rotating display apparatus is provided. The rotating display apparatus includes a pixel array and a control device. The pixel array is capable of rotating around a rotation axis in the pixel array, the pixel array includes a plurality of pixel units, and the plurality of pixel units are arranged in a plurality of pixel columns distributed in a direction perpendicular to the rotation axis. Pixel units in each pixel column are arranged in a direction parallel to the rotation axis and operate at a same refresh frequency. A refresh frequency of pixel units in a pixel column close to the rotation axis is less than a refresh frequency of pixel units in a pixel column far away from the rotation axis. The control device is configured to control the pixel units in each pixel column to operate at a refresh frequency corresponding to the pixel column.

The present invention provides a display panel, a driving method thereof, and a display apparatus, belongs to the field of display technology, and can solve the problem of mutual interference between two display modes in the existing transflective display apparatus. The display panel of the present invention includes: a plurality of reflective pixels, which perform image display using reflected light; and a plurality of self-display pixels, which perform image display using transmitted light or self-emitted light.
