therefore, led backlight led life far more than the ccfl backlight. five-led backlight technology advantages: high brightness led backlight brightness adjustment range, the flexibility to adjust the light frequency, frequency much higher than the ccfl backlight, so the presentation of motion picture perfectly. the aditional ccfl backlight flickering lamp light low frequency performance of dynamic scenes, the possible jump of the screen. as a passive lcd display, and will not light itself, it relies on backlight will be light through the display panel to show graphic images. therefore, the backlight of lcd tv technology directly affects the quality. the aditional liquid crystal displays commonly used cold cathode fluorescent lamps (cold cathode fluorescent lam, ccfl) as the light source, and it is caused ccfl lcd color is lacking, with poor color reproduction. writing board (http://www.flashingboards.com/) led backlight technology advantages of the two: light elegant led backlight is the number of grid-like semiconductors, each "grid" has an led in both the semiconductor, so that you can successfully planar source. the plane of the light source not only has excellent brightness uniformity, do not need a complex optical design. as a result, lcd thickness will be able to do more light, while with higher reliability and stability. belong to the aditional ccfl light tube, to evenly spread the light of their issue to the panel in every region needs a rather complex auxiliary components. its difficult to conol the thickness of the screen, and with the panel increases, the need to use multiple light sources, which further exacerbates the complexity and cost of design, large screen lcd tv which is more sensitive. for example, 50 inches above the lcd or tv product.neon signs california (http://www.flashingboards.com/) |
