DISPLAY APPARATUS

摘要

A display apparatus includes: a timing control block which outputs image data based on external image data and control signals, and generates data and gate-side control signals based on the external control signal; a source drive block which converts the image data into a data voltage based on the data control signal; a low frequency detection block which detects a low power drive period based on the external control signal and generates a power control signal, a state of which is determined based on a result of the detection; an integrated chip which receives first and second drive voltages and includes a first switch block that turns off a circuit of the source drive block based on the power control signal during the low power drive period; a gate drive circuit which generates a gate signal based on a gate control signal from the integrated chip; and a display panel.

1. A display apparatus comprising:
a timing control block which outputs image data based on external image data in response to external control signals, and generates a data control signal and a gate-side control signal based on the external control signal; a source drive block which converts the image data into a data voltage in response to the data control signal; a low frequency detection block which receives the external control signal, detects a low power drive period based on the external control signal and generates a power control signal, a state of which is determined based on a result of the detection of the low power drive period; an integrated chip which receives first and second drive voltages, wherein the integrated chip includes a first switch block which turns off a circuit of the source drive block in response to the power control signal from the low frequency detection block during the low power drive period; a gate drive circuit which generates a gate signal in response to a gate control signal from the integrated chip; and a display panel which receives the gate signal and the data voltage and displays an image.
