LIQUID CRYSTAL DISPLAY AND ELECTRONIC DEVICE IMPROVING SOUND QUALITY AND PROVIDING HIGH-QUALITY AUDIO DATA

摘要

PURPOSE: An LCD(Liquid Crystal Display) and an electronic device are provided to obtain a signal having a large signal-to-noise ratio and small glitch when a digital-analog converter converts a digital signal so as to improve sound quality and produce audio data with high quality. CONSTITUTION: An LCD includes at least one pixel formed on an insulating substrate, at least one source signal line and at least one gate signal line. The LCD further includes a digital-analog converter(101) for converting a digital audio signal input from an external device into an analog audio signal, a signal line driver circuit(109) for driving the gate signal line or the source signal line, and a power supply circuit(102) for supplying the same voltage to the signal line driver circuit and the digital-analog converter.
