DRIVING METHOD FOR A DISPLAY DEVICE AND A DISPLAY DEVICE
The present disclosure relates to a driving method for a display device and a display device. The display device includes a display driver, the display driver includes a plurality of driving channels each of which drives corresponding display unit according to display data in a pulse width modulation manner within one frame period, the method comprises: selectively enabling, in each sub-frame subset among a plurality of different sub-frame subsets of the frame period, different channel subset among a plurality of channel subsets of the plurality of driving channels to drive corresponding display unit, wherein each channel subset of the plurality of channel subsets includes two or more driving channels among the plurality of driving channels.
MULTI-HALF-TONE IMAGING AND DUAL MODULATION PROJECTION/DUAL MODULATION LASER PROJECTION
Smaller halftone tiles are implemented on a first modulator of a dual modulation projection system. This technique uses multiple halftones per frame in the pre-modulator synchronized with a modified bit sequence in the primary modulator to effectively increase the number of levels provided by a given tile size in the halftone modulator. It addresses the issue of reduced contrast ratio at low light levels for small tile sizes and allows the use of smaller PSFs which reduce halo artifacts in the projected image and may be utilized in 3D projecting and viewing.
DISPLAY DEVICE AND OPERATING METHOD THEREOF
A display device that achieves both high detection sensitivity of the touch sensor unit and smooth input on the touch sensor unit is provided. A method for driving a display device includes a first period and a second period. The display device includes pixels, a gate driver, and a touch sensor unit. The touch sensor unit detects a touch in the first period and stops detecting a touch in the second period. The gate driver supplies signals to some of the pixels and does not supply signals to the other pixels in the second period.
Controlling emission rates in digital displays
A display device may include pixels that display image data. The display device may also include a circuit that receives pixel data having a gray level for at least one pixel, such that the pixel data corresponds to a frame of the image data and the frame includes sub-frames. The pixel data causes the circuit to provide at least one current pulse to the at least one pixel according to a first order of the sub-frames. The circuit may also receive a second order of the sub-frames, such that the second order is mapped with respect to the first order, and at least one current pulse is provided to the at least one pixel according to the second order. As such, visual artifacts depicted on the display are reduced.
