Abstract
A display apparatus and a display control circuit which may contain an occurrence of the inappropriate brightness, such as flickering, at the time of pausing driving are provided. A scan period (St1, St2) during which a display panel drive device scans a display panel device and a retention period (Vt1) during which the display panel drive device does not scan the display panel device alternate and a timing control device causes the display panel drive device to scan the display panel device a plurality of times in the scan period when at least the brightness (Lb1) of the backlight device is changed.
Claims10
A display apparatus, comprising:
- a backlight device configured to emit a light;
- a backlight drive device configured to drive the backlight device;
- a display panel device configured to control a transmittance of the light emitted by the backlight device at least for each pixel;
- a display panel drive device configured to scan the display panel device to cause the transmittance to be controlled;
- a timing control device configured to control timing at which the display panel drive device scans the display panel device and a brightness of the backlight drive device, wherein
- a scan period during which the display panel drive device scans the display panel device and a retention period during which the display panel drive device does not scan the display panel device alternate;
- and
- the timing control device is configured to cause the display panel drive device to scan the display panel device a plurality of times in the scan period when it changes at least the brightness of the backlight device.
A display control circuit configured to control a backlight drive device configured to drive a backlight device which emits a light and a display panel drive device configured to scan the display panel device to cause an amount of transmittance of the light emitted by the backlight device to be controlled, the display control circuit further comprising
- a timing control device configured to cause the display panel drive device to scan the display panel device a plurality of times in a scan period in which the display panel drive device scans the display panel device when at least the brightness of the backlight device is changed, wherein
- the scan period and a retention period in which the display panel drive device does not scan the display panel device alternate.
