區塊動態驅動之背光模組及其抬頭顯示裝置
國立清華大學
2014/11/01
本發明係關於一種區塊動態驅動之背光模組及其抬頭顯示裝置,其中該區塊動態驅動之背光模組係同時具有一指向性透鏡單元與一光勻化單元,該指向性透鏡單元可收斂背光模組內的光源組所發出的光的發散角,並且,該光勻化單元可進一步地將光均勻化,使得液晶顯示器之所有顯示區域皆具有均一性的亮度,則駕駛者在其可視範圍之中所看到所有影像皆是一個清晰的影像;此外,背光模組內的每一個光源組皆具有一紅光LED元件、一綠光LED元件、一藍光LED元件與一白光LED元件,該些光源組可根據控制電路板之控制而使其紅光LED元件、綠光LED元件、藍光LED元件或白光LED元件發光,進而達到區塊動態顯示之目的。 The present invention relates to a sectional dynamic-driving backlight module and a head-up display device thereof, wherein the sectional dynamic-driving backlight module comprises an optical-directional lens unit and an optical-homogenizing unit. The optical-directional lens unit is provided for converging the light beams emitted by the light source assemblies in the backlight module into light beams with a smaller divergent angle, and the optical-homogenizing unit is used for further homogenizing the light beams, so as to make all display regions of the LCD show a uniform illumination; therefore all images showed on a eyebox of the driver are distinct. Besides, each of the light source assemblies consist a red light LED chip, a green light LED chip, a blue light LED chip, and a white light LED chip, and these LED chips may be controlled by a controlling PCB for lighting respectively or simultaneously, so as to achieve the sectional dynamic display.
