74-1: Application of Transfer Technology to Manufacturing of Transmissive OLED and Reflective LC Hybrid (TR-Hybrid) Display

Abstract

Our previously established transfer technology using an inorganic separation layer was applied to enable a novel through electrode structure including a conductive material exposed after separation. Using this structure, we succeeded in fabricating a transmissive OLED and reflective LC hybrid display.

56‐3: New Process to Fabricate Hybrid Display

“…Thus, this process allows panels to be fabricated with high yields. Figure 4 shows a structure fabricated by using the process for forming an OLED control circuit and a reflective LC control circuit over a single substrate (left, structure A) and a novel structure fabricated by the process for forming an OLED control circuit and a reflective LC control circuit over different substrates and then attaching the substrates together (right, structure B) [29]. These structures differ noticeably in that the OLED control circuit and the reflective LC control circuit occupy the same layer in structure A and different layers in structure B.…”

“…In SID 2016, we reported a next-generation OS-based hybrid display that can display images by using OLEDs and reflective LCs [27][28][29]. Display modes of the hybrid display are shown in Figure 1.…”

16‐1: Low‐Power Oxide‐Semiconductor Display System

“…An image data stream from a host PC is converted into the desired data format by the display controller, which comprises a printed circuit board (PCB) incorporating OS LSI, and is then transmitted to the OS display. Note that the OS display system is constructed using any of the hybrid displays [5][6][7] as the OS display and any of the OS FPGAs [12][13][14][15][16] as the OS LSI.…”

“…Such OS displays reduce power consumption because they can perform idling stop (IDS) display [3,4], in which the image refresh rate is extremely low when the image is not changed; this can be attributed to the good data retention characteristics of pixels including the OS-FETs. Moreover, hybrid displays [5][6][7] of an organic light-emitting diode (OLED) display and a reflective liquid crystal display (RLCD) solve the performance tradeoff dilemma.…”

46‐4: 513‐ppi Hybrid Display with Stacked Transistors

“…Recently, we developed a low-power-consumption display, in which a reflective LCD and an OLED display are formed over a single substrate (hybrid display) [1][2][3]. OLED display is employed under low illumination, whereas the reflective LCD is used under high illumination.…”
