58.2: High‐Performance Large‐Size OLED Tv with Ultra Hd Resolution

“…The white OLED fabrication process is already explained in our prior publication [3]. After the tandem OLED device was deposited using the thermal evaporator, the sputtering process was used to fabricate the top cathode structure.…”

“…On this prototype, the OLED device had a bottom-emitting architecture with common transporting layers that had superior image quality. At SID 2013, we successfully demonstrated the world's first 65-inch side-by side (SBS) AMOLED television with 83% NTSC color gamut [3]. The panel was produced using a fine metal mask for red/green/blue color patterning and the dam-and-fill technology for encapsulation.…”

Shoot‐through current reduction scheme for low power LTPS TFT programmable shift register

“…As a result, large-size televisions with ultra-definition (3840 × 2160) resolution have come into the display market and 120 and 240 Hz have become common frame rates of display applications. [2][3][4][5][6][7][8] However, because the high resolution and frame rate increase a horizontal line frequency substantially, it is hard to charge row and column lines at target voltage levels within a line time.…”

Letter: Dual‐mode oxide thin film transistor shift register for external compensation in active‐matrix organic light emitting diode displays

“…Active matrix organic light emitting diode (AMOLED) displays have expanded its application from small‐size mobile displays to large‐size televisions with advantages of superior image quality and thinner module . On the other hand, there exist several problems such as OLED degradation, threshold voltage, and mobility variation of thin film transistors (TFTs), supply voltage drop, and the like .…”

“…Active matrix organic light emitting diode (AMOLED) displays have expanded its application from small-size mobile displays to large-size televisions with advantages of superior image quality and thinner module. 1,2 On the other hand, there exist several problems such as OLED degradation, threshold voltage, and mobility variation of thin film transistors (TFTs), supply voltage drop, and the like. 3,4 In particular, because all issues have to be simultaneously compensated for in large-size television applications that require the long lifetime, external compensation schemes have been incorporated with sensing operation as well as scanning operation.…”
