一种直下式LED背光源控制系统
摘要：
本实用新型公开了一种直下式LED背光控制系统，包括主控IC、T-CON时序控制电路及直下式LED背光源，直下式LED背光源由多个LED背光区块组成，主控IC通过T-CON时序控制电路连接直下式LED背光源，此外还包括光感应模块、LED背光控制单元及LED背光驱动单元，光感应模块及主控IC连接LED背光控制单元，LED背光控制单元通过LED背光驱动单元连接直下式LED背光源。本实用新型在环境温度较暗时降低直下式LED背光源的亮度，如此在现高对比度和色彩保护度的同时又进一步降低能耗，并保证了在不同环境亮度下的最佳观看效果。
摘要（英）：

The utility model discloses a bottom lighting light-emitting diode (LED) back light control system, which comprises a main control integrated circuit (IC), a T-CON time sequence control circuit and a bottom lighting LED back light which is composed of a plurality of LED back light blocks, and the main control IC is connected with the bottom lighting LED back light through the T-CON time sequence control circuit. The bottom lighting LED back light control system further comprises a photo induction module, an LED back light control unit and an LED back light driving unit. The photo induction module and the main control IC is connected with the LED back light control unit which is connected with the bottom lighting LED back light through the LED back light driving unit. The bottom lighting LED back light control system is capable of reducing the brightness of the bottom lighting LED back light, reduces energy consumption while reproducing high contrast and color protection degree, and ensures optimum viewing effect in different environment brightness.
