Patent Searching and Data


Title:
DISPLAY APPARATUS AND DRIVING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/134753
Kind Code:
A1
Abstract:
Provided are a display apparatus and a driving method therefor. The display apparatus comprises a polarity control circuit (10), wherein the polarity control circuit (10) is respectively connected to a control signal end (Con1), a first data signal end (D11) for providing a positive-polarity data signal, and a second data signal end (D12) for providing a negative-polarity data signal. Under the control of a control signal, the polarity control circuit (10) can output, to each data line, a data signal with a continuously changing polarity, and at the same moment, the polarity control circuit can output data signals with opposite polarities to data lines connected to two adjacent sub-pixels of the same color in the same row; therefore, when the signal coupling problem is solved, the problem of a polarization phenomenon of liquid crystal molecules is effectively prevented.
