    • The user observes a liquid crystal display panel screen positioned within a lens barrel through a lens. An infrared LED that emits pulses of light and a phototransistor are positioned in an eyecup against which the user's eye is pressed. An ambient light detecting circuit provides a control signal showing whether or not the user's eye is pressed against the eyecup and a control signal showing the amount of ambient light on the basis of the output signal of the phototransistor. A control circuit controls the luminance of a backlight unit according to the control signals. When the user's eye is not pressed against the eyecup, the display luminance is reduced to zero and the display is turned off. The display luminance is enhanced only when the amount of ambient light is large. Thus, needless power consumption can be avoided, and the screen can be satisfactorily observed even if a large quantity of light enters into the ocular part where the ambient light is bright.
    • 用户通过透镜观察位于镜筒内的液晶显示面板屏。 发射光脉冲的红外LED和光电晶体管位于用户眼睛被按压的眼罩中。 环境光检测电路提供控制信号,该控制信号表示用户的眼睛是否被按压眼罩,以及控制信号,其基于光电晶体管的输出信号表示环境光量。 控制电路根据控制信号控制背光单元的亮度。 当用户的眼睛没有按压眼罩时,显示亮度降低到零,显示关闭。 只有当环境光量大时,才能提高显示亮度。 因此,可以避免不必要的功率消耗,即使大量的光进入环境光亮的眼部,也能令人满意地观察屏幕。
