The present disclosure provides an organic compound, an electron transport material, and an application thereof. The organic compound has a structure as shown in Formula I. Design of molecular structure and substituents enables it to undergo tridentate coordination or tetradentate coordination with metal, and more stably and firmly combination with metal, so that it has stronger stability and longer working life when used as an electron transport material, which effectively solves a problem of rising drift voltage. The organic compound has greater rigid distortion, which can suppress an increase of intermolecular attraction and prevent it from forming a planar structure to cause excessive intermolecular attraction. The organic compound is used as an electron transport material, and can be applied to an electron transport layer and/or an electron injection layer of an OLED device, which can effectively improve luminous efficiency and working life of the device, and reduce turn-on voltage.

Organic compound, an electron transport material and an application thereof

A display device includes an eyeball tracking inductor, a display panel and a processor, where the processor is electrically connected to the eyeball tracking inductor and the display panel separately; the eyeball tracking inductor is configured to identify user eyeball image information; the processor is configured to determine a gaze region and a split view region of a user viewing the display panel, according to the user eyeball image information, control the gaze region to be displayed at a first resolution, and control the split vision region of the display panel to be displayed at a second resolution, where the first resolution is greater than the second resolution.

Display device and display driving method for a display panel

Provided are a vehicle instrument, a display method, and a vehicle speed monitoring display system. The vehicle instrument includes a display panel including an indicator structure used together with a scale on the dial for reading; a dial exposed by the display panel; and an actuating mechanism connected to the display panel and configured to control a movement of the display panel relative to the dial. The vehicle instrument has a first state, in which the display panel and the dial are in a first positional relationship, the display panel displays a first pattern region, and the first pattern region and the dial are in a second positional relationship; and a second state, in which the display panel and the dial are in a third positional relationship, the display panel displays the first pattern region, and the first pattern region and the dial are in the second positional relationship.

Vehicle instrument, display method of the same, and vehicle speed monitoring display system

Provided is a display panel having a display area including a first display area and a second display area. The display panel includes: a substrate; an array layer; a display layer including light-emitting elements each including an anode, a light-emitting layer and a cathode that are sequentially stacked; the light-emitting elements comprises first light-emitting elements and second light-emitting elements; a state switching layer located at a side of the display layer facing away from a display surface of the display panel and located in the first display area, wherein in a direction perpendicular to the display panel, the state switching layer overlaps the first light-emitting elements; the state switching layer is switchable between a first state and a second state, and the state switching layer has a smaller light transmittance in the first state than in the second state; and an optical element.

Display panel and display device

The present disclosure provides a display panel and a display apparatus. The display panel includes: light-emitting elements which include a first light-emitting element that emits light of a first color having a wavelength ranging from &#x3bb;1 to &#x3bb;2, a second light-emitting element that emits light of a second color having a wavelength ranging from &#x3bb;3 to &#x3bb;4, and a third light-emitting element that emits light of a third color having a wavelength ranging from &#x3bb;5 to &#x3bb;6; and first to third capping layers respectively covering light-exiting sides of the first to third light-emitting elements.
