Display device with dual data drivers
A virtual reality system and a display device that can be used, for example, as part of the virtual reality system. The display device can have more than one data driver, such as an even row data driver and an odd row data driver. The display device can have a configurable resolution such that one region of the display device operates at full resolution while another region of the display device operates at a reduced resolution. The virtual reality system can also track an eye gaze and adjust the full resolution region of the display device to track the eye gaze.
1. A display device comprising:
a display screen including:
a first pixel row of first pixels having respective storage capacitors, the first pixels connected to a first scan line;
a second pixel row of second pixels having respective storage capacitors, the second pixels connected to a second scan line;
a third pixel row of third pixels having respective storage capacitors, the third pixels connected to a third scan line;
first data lines connected to the first pixel row and the third pixel row, but not to the second pixel row; and
second data lines connected to the second pixel row, but not to the first and third pixel rows; and
a first data driver circuit to drive the first pixel row via the first data lines over a first time period, and to drive the third pixel row via the first data lines over a third time period not overlapping with the first time period;
a second data driver circuit to drive the second pixel row via the second data lines over a second time period, the second time period overlapping with both the first time period and the third time period; and
a scan driver circuit to drive a first scan pulse onto the first scan line over a portion of the first time period to scan data voltages of the first data lines onto the first pixel row, a second scan pulse onto the second scan line over a portion of the second time period to scan data voltages of the second data lines onto the second pixel row, and a third scan pulse onto the third scan line over a portion of third time period to scan data voltages of the first data lines onto the third pixel row, wherein the second scan pulse overlaps in time with both the first scan pulse and the third scan pulse.
2. The display device of claim 1 , wherein the first pixel row is an odd pixel row and the second pixel row is an even pixel row.
3. The display device of claim 1 , wherein the first pixel row and the second pixel row are adjacent pixel rows.
4. The display device of claim 1 , further comprising:
a fourth pixel row of fourth pixels having respective storage capacitors, the fourth pixels connected to a fourth scan line,
wherein the second data lines are further connected to the fourth pixel row but not the third pixel row.
5. The display device of claim 1 , wherein the first pixels and the second pixels are OLED pixels.
6. The display device of claim 1 , wherein the display device is a virtual reality device.
7. The display device of claim 1 , wherein the first data lines are not connected to the second pixel row, and the second data lines are not connected to the first pixel row.
