“…Therefore, a well-defined color filter array is widely applied to white OLED emitter to achieve a PPI over 3000. 157 To avoid the absorption loss from color filters, eMagin proposed a novel direct patterning approach and demonstrated an RGB OLED with 2645 PPI. By removing the color filters, both maximum brightness and power efficiency can be improved.…”

Recently, "liquid crystal display (LCD), organic light-emitting diode (OLED), or micro-light-emitting diode (LED): who wins?" is a heated debatable question. In this review article, we provide a comprehensive overview of these three promising display technologies through nine display performance indicators, including ambient contrast ratio, motion picture response time, viewing angle and angular color shift, color gamut, resolution density, power consumption, cost, lifetime, and thin profile and panel flexibility. The advantages and disadvantages of each technology are analyzed, and their future perspectives are discussed.

“…Figure 9 shows a drawing of cross-section after photolithography patterning and stripping of photoresist residues to pinpoint the possible degradation sources. (1) The top surface properties of the OLED stack might be affected by the residue of the photoresist and be chemically modified due to the chemicals in the photolithography processes. (2) The bulk OLED materials in the OLED stack might be damaged from the ambient, UV light, solvent exposure in a photolithography process.…”

Resolution and brightness are the essential figure‐of‐merits for the microdisplay development needed for AR and VR applications. In this presentation, we show our technology development toward high‐resolution FMM‐free direct R‐G‐B OLED microdisplays. We show the schematic fabrication setup and integration route to fabricate red, green, and blue OLED pixels side‐by‐side by the OLED photolithographic patterning processes. We demonstrate a 1µm line and space feature with the photoresist and transfer the pattern to an OLED stack. With the high resolution of photoresist, high aperture ratio, and high‐resolution multicolor OLED pixel arrays are demonstrated. We also investigate the possible OLED degradations induced in the photolithography process. With the innovations in the process steps, OLED stacks, process environments, and photoresists, we demonstrate a breakthrough in the reliability of photolithography patterned OLED.

“…eMagin introduced the world's-first full-color video OLED microdisplay products in 2001 [19] and recently released ultra-high luminance 2k by 2k displays with 9.3-micron pitch pixels. BOE recently announced 5466 ppi OLED microdisplays [20]. Both announcements show that OLED technology is capable of making over-50 megapixel displays on future OS backplanes.…”

VR and AR near‐to‐eye (NTE) technologies offer the potential for an ultimate large display experience with extreme portability at low‐cost for medical, workstation, entertainment, and communications applications, among others. However, AR and VR have yet to achieve even a small fraction of this potential to date. Seven recent technical advances are among key developments that may finally bring virtual imaging to the display market forefront.
