46‐4: High Frame Rate Scanning Backlight System For Gaming PC Display with IGZO‐TFT Technology

Abstract

The rapid expansion of the gaming PC market in recent years has increased the demand for high frame rate display modules. Especially for laptops, the demand for thinner profiles and narrower borders also continues to be strong. We have developed an LCD module with a combination of a high frame rate LC panel based on IGZO‐TFT technology and a scanning backlight that enables high moving picture quality in a thin profile with narrow borders on three sides. The scanning backlight has fewer segmented areas. Nevertheless, our LCD achieves higher moving picture quality by using a fast response LC.

“…Impulse-type backlights such as flashing backlights and scanning backlights are known to have different moving picture quality depending on the position on the screen [11][12][13].…”

Theoretical Modeling of a Temperature-Dependent Threshold-Voltage Shift in Self-Aligned Coplanar IZTO Thin-Film Transistors

“…Recently, demand for higher field-effect mobility (μ FE ) and smaller pixel size has grown as part of efforts to develop next-generation displays with ultrahigh resolution beyond 8 K, a refresh rate greater than 240 Hz, and a pixel density above 1000 pixels per inch. Organic light-emitting diode (OLED) technology, which is dominating the high-end display market, requires a relatively high current density of several microamperes due to the current-driving method of light-emitting devices, unlike that of voltage-driven liquid crystal displays. − It is therefore important to precisely understand the self-heating effects in TFTs. Amorphous indium-gallium-zinc oxide ( a -IGZO) is a promising channel material that has been implemented in display backplanes since its invention by Hosono and co-workers in 2004 .…”
