Abstract
A liquid crystal display (LCD) panel driver circuit includes a control circuit board, and an LCD panel. The LCD panel includes scan lines and data lines. The control circuit board includes a data driver module that drives the data lines. The LCD panel is configured with a switch module, and the data driver module is coupled to each of the data line via the switch module. The switch module is turned of before a drive of a last line of the scan line ends, and the switch module is turned on when a drive of the next row of the scan line starts.
Claims16
A liquid crystal display (LCD) panel driver circuit, comprising:
- a control circuit board;
- and
- an LCD panel that comprises scan lines and data lines;
- wherein the control circuit board comprises a data driver module that drives the data lines, and a scan driver module that drives the scan lines;
- the data driver module is coupled to each of the data lines via a switch module, and the switch module is arranged at one end of the LCD panel adjacent to the data lines;
- within each scanning period of the LCD panel, the switch module turns off a signal of the data driver module when a drive of a last row of the scan line ends and switches to a drive of a next row of the scan line, and the switch module turns on the signal of the data driver module when a preset delay time of the switch module is reached.
A liquid crystal display (LCD) panel driving method, wherein the LCD panel driver circuit comprising scan lines, data lines, and a data driver module that drives the data lines;
- the LCD panel driving method comprises:
- A:
- connecting to a switch module between the data driver module and each of the data line, wherein the switch module is arranged at one end of the LCD panel adjacent to the data lines;
- B:
- within each scanning period of the LCD panel, ending a drive of a last row of the scan line, and switching to a drive of a next row of the scan line, the switch module turns off a signal of the data driver module, and the switch module turns on the signal of the data driver module when a preset delay time of the switch module is reached.
A liquid crystal display (LCD) device, comprising:
- an LCD panel driver circuit, wherein the LCD panel driver circuit comprises a control circuit board, and an LCD panel;
- the LCD panel comprises scan lines and data lines;
- the control circuit board comprises a data driver module that drives the data lines, and a scan driver module that drives the scan lines;
- the data driver is coupled to each of the data lines via a switch module, and the switch module is arranged at one end of the LCD panel adjacent to the data lines;
- within each scanning period of the LCD panel, the switch module turns off a signal of the data driver module when a drive of a last row of the scan line ends and switches to a drive of a next row of the scan line, and the switch module turns on the signal of the data driver module when a preset delay time of the switch module is reached.
