Abstract: A display with multiple light sources sharing a device driver is disclosed. In one embodiment of the present invention a display includes a first device driver, a first light source, a second light source and a first light-source selection circuit which is coupled to the first device driver, the first light source and the second light source. The first light-source selection circuit is configured to pair the first device driver with the first light source during a first time interval and to pair the first device driver with the second light source in a second time interval.

Abstract: Display Pixel Design and Control for Lower Power and Higher Bit Depth Craig Michael Waller A method to generate pixel control signals more rapidly and with less overhead is disclosed. The method generates pixel control signals for a first block of pixels having a first first-block pixel and a second first-block pixel and a second block of pixels having a first first-block pixel and a second second-block pixel. A first-block base control signal that is shared by the first block of pixels is generated. A first first-block sharpening control signal for the first first-block pixel is generated and a first second-second-block sharpening control signal for the first second-block pixel is generated. The first first-block pixel control signal is generated using the first first-block sharpening signal and the first-block base control signal. The first second-block pixel control signal is generated using the first second-block sharpening signal and the second-block base control signal.

A first sharpening control signal for the first pixel is generated and a second sharpening control signal for the second pixel is generated. The first pixel control signal is generated using the first sharpening signal and the base control signal. The second pixel control signal is generated using the second sharpening signal and the base control signal. The base control signal is stored in a first memory cell; the first sharpener control signal is stored in a second memory cell; and the second sharpener control signal is stored in a third memory cell.

Abstract: The present invention relates to a laser light source optical projection architecture, which comprises a laser light source group, a color control device, a phosphor device and an optical filter group. Accordingly, the laser light source optical projection architecture does not require to synchronize the phosphor device with the color field sequential display system, and the color control (ratios of the color duty) does not need to be determined in advance, i.e. at the time the color control device is manufactured. Various color field ratios can be achieved by adjusting positions of the specific color control device to obtain different red, blue and green color field durations, allowing easy electronic control of the color field duty cycles.

Abstract: A manufacturing method of micro LED display module is provided. The micro LED display module comprises a driver chip block, a LED block, a circuit board and a color layer. The driver chip block has a plurality of pixel electrodes. The LED block is disposed in the driver chip block and has two semiconductor layers and a plurality of trenches. One of the two semiconductor layers is electrically connected to the pixel electrodes and the other is electrically connected to the light transmissive conductive layer. The trenches define a plurality of micro LED pixels arranged in an array. Each trench at least penetrates through the light emitting layer and one of the semiconductor layers. Each micro LED pixel corresponds to one of the pixel electrodes. The circuit board is electrically connected to the driver chip block, and the color layer is disposed on the light transmissive conductive layer.
