OLED vehicle lamp control circuit

Abstract

The invention provides an OLED vehicle lamp control circuit. The control circuit comprises a microprocessor, a first switch group, a second switch group and a plurality of linear constant-current modules; the linear constant-current modules are in one-to-one correspondence with corresponding OLED light sources; the microprocessor is used for generating an on-off control signal and a luminance control signal according to a received vehicle lamp animation signal; the first switch group is used for generating on-off switching signals of each OLED light source according to the on-off control signal from the microprocessor, so as to control the on-off of each OLED light source through the linear constant-current module corresponding to the OLED light source; and the second switch group is used for generating luminance switching signals of each OLED light source according to the luminance control signal from the microprocessor, so as to control the luminance of each OLED light source through the linear constant-current module corresponding to the OLED light source. By virtue of the OLED vehicle lamp control circuit provided by the invention, the dynamic display effect of the OLED light sources is realized, and various kinds of display requirements of the vehicle lamp can be satisfied.

Description

technical field [0001] The invention relates to the technical field of control circuits, in particular to an OLED vehicle light control circuit. Background technique [0002] Car lights are the lamps on the vehicle. They are tools for lighting the road when the vehicle is driving at night, and are also a prompting tool for sending out various vehicle driving signals. Generally, car lights include headlights, tail lights, turn signals, and the like. [0003] In the prior art, LEDs, as the preferred light source for automobile rear lights, have been widely and maturely applied to automobile signal lights with various functions. As a point light source, when LED is applied to a signal light with a certain function, multiple LEDs are generally required to realize a function. In practical applications, it has the following disadvantages: [0004] (1) The luminous effect of multiple LEDs is difficult to achieve good luminous uniformity without relying on a good optical reflecti...

AI Technical Summary

Problems solved by technology

[0004] (1) The luminous effect of multiple LEDs is difficult to achieve good luminous uniformity without relying on a good optical reflection system and the use of light distribution mirrors;

[0005] (2) Due to the limitation of the luminous effect of the point light source, it is difficult to realize the dynamic effect of multiple LED light emission through the LED light source control circuit, and the expected visual effect cannot be achieved

[0009] By arranging the OLED light source and using its outstanding planar light source performance, the OLED car light source can show a rich dynamic display effect, thus well making up for the unevenness of the existing LED car light. single disadvantage
