78-4:Distinguished Paper: A 2.78-in 1058-ppi Ultra-High-Resolution Flexible OLED Display Using CAAC-IGZO FETs

Abstract

We have successfully fabricated a 2.78-in 1058-ppi flexible OLED display. This display exhibits the highest pixel density in the world among flexible displays using thin film transistors. The display can be bent with a curvature radius R 1 mm and shows a high resistance.

24‐4: Foldable AMOLED Display Utilizing Novel COE Structure

“…Its flexible property prompts the application of display from rigid and flat shape to a fixed curve, bendable, and even foldable. Fixed curve shape has been widely applied in mobilephone and watches [1][2][3][4][5][6][7][8][9][10][11]. However, the mechanical reliability of panels with bendable or foldable features is a major impediment to the mass production of such products.…”

24‐3: An 8.34‐inch 1058‐ppi 8K x 4K Flexible OLED Display

“…Flexible organic light-emitting diode (OLED) displays have been suggested as devices that satisfy these requirements [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. We have fabricated a variety of flexible OLED displays [1][2][3][4][5][6][7][8][9][10][11][12], such as a side-roll display with curved edges [5], foldable displays [6][7], and a large seamless multidisplay [8], as well as OLED displays with high pixel density using glass substrates [19][20][21][22].…”

“…At SID 2016, we presented a 2.78-inch ultra-high-pixel density (1058 ppi) flexible OLED display [11]. This display can achieve a high color gamut and excellent viewing-angle characteristics by suppressing crosstalk and light leakage from adjacent pixels.…”

Achieving a foldable and durable OLED display with BT.2020 color space using innovative color filter structure

“…In recent years, flexible active-matrix organic light-emitting diode (AMOLED) displays have attracted tremendous attention because of its unique properties including high display quality, light weight, flexibility, and freedom for creative and innovative applications. [1][2][3][4][5][6][7][8][9][10][11][12] However, the mechanical reliability of panels with bendable or foldable features has always hindered the mass production of such flexible products. Continuous mechanical distortion would induce device degradation or accelerate the breakdown of such devices.…”
