Abstract: An electronic device includes a substrate and a timing control module. The timing control module transmits a plurality of timing control signals to the substrate. The timing control module includes an overcurrent protection circuit for detecting the timing control signals. The overcurrent protection circuit includes a subtractor and a comparator electrically connected to the substractor. The timing control signals include a first timing control signal and a second timing control signal. The subtractor calculates a first current difference value between a draw current value of the first timing control signal and a draw current value of the second timing control signal. The comparator compares the first current difference value with a first threshold and, when the first current difference is greater than or equal to the first threshold value, the overcurrent protection circuit performs an overcurrent protection mechanism.

Abstract: A gate pulse modulation waveform-shaping circuit includes an input terminal, an output pair, and a gate pulse modulation waveform-shaping control circuit. The input terminal receives a control signal. The output pair is connected to a scan line for outputting a gate output voltage. The gate pulse modulation waveform-shaping control circuit is connected to the output pair for adjusting a voltage waveform on the scan line. The gate pulse modulation waveform-shaping control circuit is based on the control signal to use a time interval or fixed discharge voltage to generate a desired delay for adjusting a discharge slope thereby generating different discharge time on the scan line, so that the gate output voltage has a voltage waveform including at least two waveform segments each with a non-zero sliding slope and at least two waveform segments each with a zero slope.
