The remote control IR receiver PCB in traditional TV parallels to the display panel at vertical direction, and the bezel size is larger. For resolving the problem and meeting the requirement of TV with super narrow bezel, at the condition of moving PCB to the back of the panel and no occupying TV down bezel space, the IR reception lens is designed to receive remote control signals from long-range and multi-angle effectively. And super narrow bezel can also be realized on down bezel. According to geometrical optics total reflection principle and refraction law, the designed lens is simulated and analyzed by Tracepro software. The defects in lens design are checked, and then the lens structure contour is adjusted and revised. And the optimized lens structure is obtained. The results show that when IR PCB face indirectly to lens window, IR receiver can also receive effective light flux at the condition of changing the partial structure of the lens, which meets or exceeds to TV remote control test standard. The design targets of super narrow down bezel or complex and diversity appearances are realized by the optimization design.
