20150251591 | Full-screen display device of automobile taillights - A full-screen display device of automobile taillights relates to a light-emitting display technology for automobile taillights, including left and right taillights, a linked switch and a light-emitting display controlling circuit. The left and the right taillights are divided into three light-emitting zones I, II and III, wherein light-emitting diodes (LEDs), respectively for displaying red, yellow and white light, are arranged in each light-emitting zone. The light-emitting display controlling circuit includes a signal inputting circuit, a single-chip microcomputer controlling circuit, a metal-oxide-semiconductor field-effect transistor (MOS FET) switching constant-current source circuit, a light-emitting executive circuit and a power source. The signal inputting circuit is connected with a signal inputting terminal of a single-chip microcomputer; a signal outputting terminal of the single-chip microcomputer is connected with an inputting terminal of the MOS FET switching constant-current source circuit; and the MOS FET switching constant-current source circuit is connected in series with the LEDs. One advantage of the present invention is that emitted colors and brightness of each light-emitting zone are controlled by a single-chip microcomputer program. When a single function is chosen, the three light-emitting zones all display light and no light-emitting zone is idle, which makes a full use of an effective light-emitting display area of each taillight. The present invention has beautiful and striking light-emitting display, clear and intuitional light-emitting display effect, and is able to effectively reduce traffic accidents. | 09-10-2015 |
