摘要： A head-up display system is disclosed and has a transparent reflecting medium and a flat display panel. The flat display panel is disposed in front of the transparent reflecting medium at an angle with respect to the transparent reflecting medium, and generates a display image. The flat display panel has a display area of X square millimeters and has a light source that emits light with a luminous flux of Y lumens, satisfying a relationship of Y>(3e−10X2+0.0283X+2.5298), so that the display image is projected onto the transparent reflecting medium in a lensless way. With the head-up display system, the visibility of the display image projected on a front windshield is improved.

摘要： An LED area light module has a substrate and a circuit layer and a solder mask layer formed on the substrate. The solder mask layer partially covers the circuit layer for the partially exposed circuit layer to form multiple electrical contacts. An embankment wall is formed on the solder mask layer with a solder mask material for the electrical contacts to be located within the embankment wall. Multiple LED chips are mounted on the solder mask layer within the embankment wall and electrically connected to the electrical contacts. Optically-transmissive adhesive is filled and concentrated within the embankment wall and covers the LED chips by a tension force thereof, and forms an optically-transmissive adhesive layer after congealed. Accordingly, the LED area light module eliminates the use of thick frame made of metal or rubber and steps of manufacturing and mounting the frame to simplify the packaging processes.
