LED LOW HEAT AND ULTRA HIGH BRIGHTNESS BACKLIGHT UNIT AND LIQUIFIED CRYSTAL DISPLAY

摘要

In the present invention, an LED element as a point light source is constituted by a LED light source in the form of a round light source, and it is possible to prevent the deformation and wrinkle of the optical sheet due to the high heat and high heat caused by the high brightness, In order to solve the problem that the cooling system for blackening phenomenon and cooling had to be added, we developed a backlight LED with improved light efficiency and constructed it in the form of a round light source, achieving a much higher brightness than existing products, A liquid crystal display in which an LED backlight 10 is provided inside the mold frame 1 and an LCD glass 20 is attached to the outside of the mold frame 1 so as to provide an LED backlight and a liquid crystal display; The LED backlight 10 has a plurality of LED chips 12 mounted on a PCB 13 on one side of a light guide plate 11 and a heat sink plate 12 having a width larger than the width of the LED chip 12 And a metal reflective layer 15 is coated on the outer periphery of the LED chip 12.
