Abstract:
The present invention discloses organic light emitting device, manufacturing method thereof, organic light emitting display device and driving method thereof. The organic light emitting device comprises a substrate and a first electrode layer, an organic layer and a second electrode layer positioned on the substrate, the organic layer is arranged between the first and second electrode layers, the first electrode layer, the organic layer and the second electrode layer form a laminated region for emitting light in a first specific color in a positive half cycle of alternating current and an inverted region for emitting light in a second specific color in a negative half cycle of alternating current, and at least portions of projections of the laminated region and the inverted region on the substrate are not overlapped;. Technical solutions of the present invention render the organic light emitting device with adjustable light color and prolonged service life.
Abstract:
An OLED pixel unit is disclosed, which comprises an opaque region and a transparent region which are arranged side by side, the opaque region comprises an opaque display element, and the transparent region comprises at least one transparent display element. Independent operation of the opaque display element and the transparent display element is realized without affecting the transparent display in the transparent region of the OLED pixel unit, thus increasing the resolution of the OLED pixel unit. A transparent display device comprising the OLED pixel unit, a method for fabricating a transparent display device, and a display apparatus are further disclosed. (FIG. 2)
Abstract:
The present disclosure provides a safe driving method, a safe driving device and a safe driving system, for a vehicle. The safe driving device includes an information processor, and a brake controller connected to the information processor. The information processor is configured to acquire vehicle information and information about a driving license of a driver, and determine, in accordance with the vehicle information and the information about the driving license of the driver, whether or not the driver meets a requirement for driving the vehicle. The information processor is further configured to, in the case that the driver does not meet the requirement for driving the vehicle, control the brake controller to brake the vehicle.
