1. , a kind of color separation shows the traffic signals time display apparatus, by being formed by housing and the display that is arranged at the electronic program gauge tap in the housing and be installed on the surface of shell, the electronic program gauge tap is by Switching Power Supply, sampling unit, control module and driving circuit are formed, wherein the input signal of sampling unit be by traffic lights come red, yellow, green three signals, three signals of its output and the input end of control module link, what control module was exported is a plurality of signals, it and the corresponding a plurality of input ends of driving circuit link, driving circuit is output as with red, the corresponding a plurality of signals of green traffic signal, it is connected with the display relevant portion, it is characterized in that described display is the pixel pipe of more than one row'"'"'s multiple rows, and each pixel pipe serve as reasons at least 8 red, green luminotron is divided into red, green two groups and form, and every row'"'"'s pixel pipe is red, green luminotron group is in parallel respectively, and by a row or two row'"'"'s pixel pipes as a light group, and with the red or green luminotron group of each light group as an input end;

  • That a plurality of output signals of electronic program gauge tap driving circuit are divided into is red with traffic, green light signals is relevant two groups, they respectively with displayer pixel pipe row'"'"'s corresponding the linking of a plurality of light groups, and, extinguish the light group chronologically successively by control module control.
