title: High Speed Digital Data Interface for OLED on Silicon Micro Display
abstract: Micro displays with low power consumption and good display quality is required in near eye displays. High data rate character is much important for high definition micro display. An OLED on silicon display with digital data interface was fabricated in TSMC 0.18um CMOS process, which employs eight high speed LVDS data input channels and one LVDS clock channel to decode the parallel 64 bit digital data. Each pixel uses a RGB layout pattern. The micro display chip achieves a high resolution image of 1600x1600 dot matrix resolution and a light intensity more than 1000cd/m2.

title: Efficient micro cavity top emission OLED with optimized Mg:Ag ratio cathode.
abstract: Micro cavity top emitting organic light emitting diodes (TEOLEDs) are now receiving prominence as a technology for the active matrix display applications. The semi transparent metal cathode plays the crucial role in realizing TEOLEDs structure. Here, we report the optimization results on Mg:Ag ratio as the semitransparent cathode deposited by vacuum thermal evaporation. The optimized Mg:Ag cathode with 1:10 ratio (wt shows a sheet resistance value as low as 5.2 O/ an average transmittance of 49.7% reflectance of 41.4% and absorbance of 8.9% over the visible spectral region (400~700 nm) The fabricated red TEOLEDs device implemented using LiF Ag (1:10) cathode shows the voltage value of 4.17 V at a current density of 10.00 mA/cm2, and current efficiencies variation from 55.3 to 50.1 cd/A over the brightness range 2,000 12,000 cd/m2. The electroluminescence (EL) spectrum displays the light emission at 608 nm wavelength with a half width of 29.5 nm. The narrow half width of red light emission is attributed to the micro cavity effects due to the semitransparent cathode.

title: High temperature resistant micro cavity OLED (organic light emitting siode) screen and production process thereof
abstract: The invention provides a high temperature resistant micro cavity OLED (organic light emitting diode) screen and a production process thereof. The screen comprises a substrate as well as an anode, a light emitting layer, a cathode and a packaging cover which are connected on the substrate sequentially; the screen further comprises a metal layer which is clamped between the anode and the substrate and comprises a part extending out of the packaging cover. The OLED screen has the advantages that the metal layer partially extends out of the packaging cover and is exposed to an open environment after packaging, so that timely cooling is facilitated, and the cooling effect of the screen is improved. The metal layer with high reflectivity is further arranged between the anode and the substrate, so that a micro cavity structure is formed between the anode and the cathode, and the efficiency of the screen can be effectively improved by the micro cavity effect of the micro cavity structure. The production process is simple and feasible, high in operability and suitable for large scale production.
