Brightness control circuits |
摘要 |
Brightness control circuits and drivers and display devices using the same. In the brightness control circuit, a current digital-to-analog converter (DAC) receives a digital code and generates a control current, and an one-shot circuit is coupled to the current DAC to generate a pulse width modulated (PWM) signal according to the control current and a clock signal. The digital code and pulse width modulated signal have an exponential relationship.
