Abstract
A display apparatus includes a display panel and a timing controller. The display panel includes a first display area on which a first gate line group is disposed and a second display area on which a second gate line group is disposed. The second gate line group is disconnected from the first gate line group. The timing controller is configured to determine a first driving frequency of the first display area based on first image data displayed on the first display area and a second driving frequency of the second display area based on second image data displayed on the second display area.
Claims20
A display apparatus comprising:
- a display panel comprising a first display area on which a first gate line group is disposed and a second display area on which a second gate line group is disposed, the second gate line group being disconnected from the first gate line group;
- and
- a timing controller configured to determine a first driving frequency of the first display area based on first image data displayed on the first display area and a second driving frequency of the second display area based on second image data displayed on the second display area.
A method of driving a display panel, the method comprising:
- determining a first driving frequency based on first input image data, wherein the first input image data is displayed on a first display area on which a first gate line group is located;
- determining a second driving frequency based on second input image data, wherein the second input image data is displayed on a second display area on which a second gate line group is located;
- and
- driving the first display area with the first driving frequency and the second display area with the second driving frequency.
A driver for a display apparatus, the driver comprising:
- a gate driver;
- and
- a timing controller configured instruct the gate driver to apply a gate clock signal of a high frequency to a first set of gate lines of the display apparatus that correspond to a first portion of input image data representing a static image during a frame period, block pulses of the gate clock signal using a masking signal to generate a gate clock signal of a low frequency, and instruct the gate driver to apply the gate clock signal of the low frequency to a second set of gate lines of the display apparatus that correspond to a second portion of the input image data representing a moving image during the frame period.
