“…On the other hand, the gamma shift on nonemissive LCDs has been well compensated 6,[38][39][40] , and the integrated linear polarizer enhances the ACR. Researchers have developed organic TFTs for plastic substrates and flexible LCDs 113 . The so-called OLCDs have lower manufacturing costs and easier scalability for large panel sizes than do flexible OLED displays.…”

Presently, liquid crystal displays (LCDs) and organic light-emitting diode (OLED) displays are two dominant flat panel display technologies. Recently, inorganic mini-LEDs (mLEDs) and micro-LEDs (μLEDs) have emerged by significantly enhancing the dynamic range of LCDs or as sunlight readable emissive displays. "mLED, OLED, or μLED: who wins?" is a heated debatable question. In this review, we conduct a comprehensive analysis on the material properties, device structures, and performance of mLED/μLED/OLED emissive displays and mLED backlit LCDs. We evaluate the power consumption and ambient contrast ratio of each display in depth and systematically compare the motion picture response time, dynamic range, and adaptability to flexible/transparent displays. The pros and cons of mLED, OLED, and μLED displays are analysed, and their future perspectives are discussed.

“…The fabrication process we have developed allows complete LC cells and organic TFTs to be manufactured on TAC film instead of glass, using standard flat-panel display equipment [3][4][5][6]. Because both the organic TFTs and LC cell materials are processable below 100°C, this allows materials with a low Tg such as TAC film (Tg~150°C) to be used as a substrate for the first time.…”

One of the challenges in see-through AR headsets is rendering outdoor scenes when there is high ambient brightness. This is because in such conditions the luminance of real objects becomes comparable to or higher than the maximum luminance of the virtual object, severely impacting the virtual image contrast. One solution to this is to use LC-based ambient dimming cells to modulate background brightness. However, conventional glass LC cells add unwanted weight and volume to headsets and cannot be biaxially curved. This talk will explain how a breakthrough liquid crystal optics technology built on ultra-thin, light bioplastic films instead of glass uniquely enables active-matrix pixelated ambient dimming on biaxially curved surfaces.

“…As a typical example, organic light-emitting diode (OLED) displays can be fabricated on flexible substrates to achieve flexibility 16 , 17 and have already been commercialized. A novel organic liquid crystal display uses an organic thin-film-transistor (TFT) array on a plastic film to replace amorphous silicon TFTs and has achieved a certain amount of flexibility 18 . However, these types of displays are flexible but nonstretchable.…”

Curved displays have recently become very popular, with wide applications for both industry and consumers. However, built upon initially flat films, most flexible displays are often incompatible with general nondevelopable surfaces. In this paper, we report a method for producing curved displays of nondevelopable shapes by using a structure-mechanics-inspired functional optimization method to design tessellation patterns that fold into the desired shapes. Representative displays in spherical and saddle shapes are demonstrated. The microfabrication process is employed for manufacturing 2D flexible foldable circuit boards, pick-and-place technology is used for placing illuminant elements onto the boards, and mold guidance is used for folding 2-D sheets into curved 3D display prototypes. The proposed technology is feasible for mass production and advances the application of next-generation curved displays.
