<p>A digital display apparatus includes an array of light-emitting pixels, each with a first and second electrode, formed on a display substrate. A plurality of chiplets is located on the display substrate, each chiplet including an electrode connection pad, a signal connection pad, and a pixel circuit. The electrode connection pad is connected to one of the first or second electrodes. Each chiplet includes one or more pixel circuits formed in the chiplet and electrically connected to the corresponding electrode and signal connection pads. A digital image signal is provided to the signal connection pad(s) of at least one of the chiplets. Each pixel circuit converts at least one digital image signal value to a continuously valued analog pixel-driving signal that controls the luminance of a pixel. The display provides higher-performance pixel circuits with digital control resulting in improved image quality.</p> |
