Abstract

The invention discloses an OLED screen device, a car lamp, and a method for manufacturing a shunt unit in the OLED screen device, relates to the technical field of car lamps, and aims to solve the technical problem that the existing OLED screen device is prone to uneven light emission. The OLED screen device of the present invention includes: a light-emitting area, the light-emitting area is provided with a shunt unit, and the shunt unit is used to prevent holes from meeting electrons in the area close to the electrode and excite organic materials to emit light. The OLED screen device of the present invention can make the OLED screen body have the same amount of holes as possible passing through the hole transport layer and the electrons passing through the electron transport layer in the area nearer to the electrode and the area farther away from the electrode. The organic light-emitting layer meets and excites the organic material to emit light, so as to effectively improve the uniformity of light emission of the OLED panel device.

Description

technical field [0001] The invention relates to the technical field of vehicle lamps, in particular to an OLED screen device, a vehicle lamp, and a method for manufacturing a shunt unit in the OLED screen device. Background technique [0002] Organic Light Emitting Diode (OLED) device is a planar light source. Compared with Light Emitting Diode (LED) point light source, it has the advantages of uniform light emission, light and thin, and customizable graphics, making it very suitable for designing innovative lighting products. [0003] For innovative car taillights, because the shape and light-emitting area of ​​OLED can be customized, there is a trend to use OLED light source as the choice of innovative light source. However, due to the different shapes of OLEDs, which are not regular shapes, and considering the position of the electrodes of OLED devices, some irregular-shaped OLED screen devices, such as: OLED screen devices with different length-to-width ratios, are prone...
