DISPLAY DEVICE USING LED CHIP

摘要

A pixel module of an electronic scoreboard using an LED(Light Emitting Diode) chip is provided to reduce the volume and weight of a pixel module of an electronic scoreboard by improving the assembly structure of a transmission part and to improve light concentration ratio from LED chips by using a convex lens. A pixel module(100) of an electronic scoreboard using an LED chip includes a printed circuit board, a light collecting unit(310), a transmission unit(300), and a supporting unit. A plurality of LED chips are arranged on the printed circuit board. The light collecting unit(310) being closely placed on the front of the printed circuit board. The light collecting unit(310) projects lights collected from the LED chips into a predetermined direction. The transmission unit(300) is equipped with an interference protection unit for neighboring LED lights.
