Different from the conventional driving scheme of the active-matrix organic light-emitting-diode display, which places the scan drivers and emission drivers at the panel bezels, the CMOS driver chiplets are proposed to sit on the glass substrate among μLEDs. The high-voltage swing buffers in the CMOS chiplet are used to drive the low-temperature poly-silicon thin-film transistors on glass backplane to enable the emission control of 300 μLEDs. A single CMOS chiplet has 20 output channels, each offering 16M-color depth with 256 grey levels realized by an 8-bit digital-to-analog converter. The maximum channel current is 247 μA and the TFT-gate-driving voltage is 15 V. IEEE |
