Abstract: Provided are a display panel and a display device. The display panel includes multiple light-emitting devices. Each of the multiple light-emitting devices includes a red light-emitting device, a green light-emitting device and a blue light-emitting device. The red light-emitting device includes a red light-emitting layer, a peak wavelength of a red spectrum emitted by the red light-emitting device is λ11, and a peak wavelength of an intrinsic emission spectrum of a red light-emitting material in the red light-emitting layer is λ12. The green light-emitting device includes a green light-emitting layer, a peak wavelength of a green spectrum emitted by the green light-emitting device is λ21, and a peak wavelength of an intrinsic emission spectrum of a green light-emitting material in the green light-emitting layer is λ22. Δ1=λ11−λ12, Δ2=λ21−λ22.

Abstract: 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.

Abstract: 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.
