The present invention relates to an integrated traffic information display device. In particular, a traffic light and various traffic signs and traffic information can be displayed on a light emitting device array arranged in a matrix form using red, blue, and green light emitting devices as one pixel. An integrated traffic information display apparatus.

Current roads are classified into ① general roads, ② automobile roads, ③ pedestrian roads, ④ bicycle roads, ⑤ overpasses, and ⑥ underground roads, depending on the use and type of road.

Traffic information devices installed on such roads include traffic lights and various traffic signs (attention signs, intersections, merged roads, bends, regulatory signs, indication signs, street signs, road condition indicators, etc.).

Traffic lights are divided into pedestrian traffic lights and vehicle traffic lights, and various traffic signs are installed in addition to the traffic lights.

1 is a view in which a conventional traffic light and traffic signs are installed on a post on a road. As shown in Fig. 1, the props 1 for installing the traffic lights are erected at the center of the road or on the road, and the traffic light transverse supports 2 are fixed at a predetermined height of the props 1 to support the traffic lights 3 and the like. A time indicator (6) is installed, and the traffic sign horizontal support (4) is fixed to another fixed height of the support (1) to install the traffic sign (5).

In this way, the traffic lights and traffic signs are complicatedly installed, so even on the road where the experienced driver first visits, it is difficult to predict where the desired traffic information can be found while checking the traffic lights and traffic signs. to be.

In order to solve this problem, Korean Utility Model Publication No. 20-0165216 discloses a traffic light using a liquid crystal display as shown in FIG. 2.

In the conventional traffic light, a thin film transistor liquid crystal display 8 representing blue, yellow, red and a separate blue indicator is arranged in one traffic light 7 so that any color is uniform by the traffic light control system. Gradually enlarged at the position, and any color of the previous state is gradually reduced to make it possible to more clearly know the time of notice of the driving or stopping of the vehicle or pedestrian according to the color of the current state and the previous state, It can't show complex traffic information because it can't show signs and other traffic information together.

In addition, the traffic light is illuminated by the lights and can be seen at night, but various traffic signs are not displayed as lights, but the luminous paint is painted to reflect the light from the street lights or the headlights of automobiles.

However, the number of traffic accidents is higher in the day, but the mortality rate is higher in the night, so that traffic signs displaying traffic information can shine so that the angle of the headlights or the fog is not right, like a bending point. It is necessary to be able to see well even where there is no effect of existing traffic signs such as lakeside.

Accordingly, it is necessary to reduce the number of deaths in the event of a traffic accident and to reduce the number of traffic accidents occurring at night by providing information on the road to the driver who lights at night by a traffic sign that emits light.

The Road Traffic Act Enforcement Rule was revised in 2005 to allow the installation of luminous safety signs in places with high fog, high number of night traffic accidents, high probability of occurrence, and insufficient visibility.

The Road Traffic Act Enforcement Regulations can be used to change the background color of three signs such as Caution, Safety, and Instruction to Matte Black, and the letters and symbols can be changed to Yellow (Caution) and White (Regulation and Instruction). I made it.

The existing signs have a black symbol (caution) on a yellow background, a black symbol (regulation) on a white background, and a white symbol (instruction) on a blue background.

The present invention has been made to solve the above problems, an object of the present invention is to provide an integrated traffic information display device that can display traffic lights, various traffic signs and traffic information as a single device.

Another object of the present invention is to provide an integrated traffic information display device capable of displaying red light, blue light, yellow light as a single light and displaying a signal which is smaller in size than a conventional traffic light.

It is still another object of the present invention to provide an integrated traffic information display device that allows a driver to identify traffic lights while the traffic lights are not illuminated at night.

In the integrated traffic information display device according to the present invention, a plurality of pixels are arranged in a matrix form using red, green, and blue light emitting devices as one pixel, and a light emitting device array divided into a traffic signal part, a traffic sign part, and a traffic information part. Wow; A traffic signal driver, a traffic mark driver, and a traffic information driver for driving the red, green, and blue light emitting devices of the traffic signal unit, the traffic sign unit, and the traffic information unit of the light emitting element array; The traffic signal driver controls the traffic signal unit of the light emitting device array to display the corresponding traffic signal, and controls the traffic sign drive unit so that the traffic sign of the light emitting device array displays the corresponding traffic sign, which is received from the traffic information center.
