摘要： An apparatus for testing a driving circuit for a display is disclosed. The apparatus includes a selecting circuit, a reference voltage generator and an analog-to-digital converter (ADC). The selecting circuit includes many input terminals and an output terminal. The input terminals are respectively coupled to many output pins of the driving circuit, while the selecting circuit is used for selecting one of the output pins to electrically connect the output terminal of the selecting circuit. The reference voltage generator is coupled to at least one of the output pins for generating a reference voltage. The ADC is coupled to the output terminal of the selecting circuit for outputting a digital value based on a difference between an output voltage outputted from the output terminal of the selecting circuit and the reference voltage produced by the reference voltage generator.

摘要： An analog-to-digital converter (ADC) is presented. The ADC includes an error amplifier, a ramp generator, and a counting circuit. The error amplifier is used for receiving an output voltage and a reference voltage, and amplifying a difference between the output voltage and the reference voltage, so as to obtain a first voltage and a second voltage. The ramp generator is used for generating a ramp voltage which is increased along with time. The counting circuit is used for starting counting a digital value when the ramp voltage is larger than or equal to the first voltage, and stopping counting and outputting the digital value when the ramp voltage is larger than or equal to the second voltage.
