“…Gan-based miniaturized light-emitting diodes (mini-LEDs) have emerged as one of the most prevalent light sources toward state-of-the-art technology due to their superiorities of low consumption, ultrahigh luminance, high efficiency, long lifespans, and mass production capability [1][2][3]. By Shrinking the dimensions of LEDs to less than 200 µm, mini-LEDs have attracted numerous attentions for the high-resolution displays [4,5], visible-light communication [6], and digital signage [7]. Currently, the most promising application of mini-LEDs is to utilize miniaturized chips as direct-lit units in locally dimmable backlights, realizing high contrast ratio and high dynamic range (HDR) for liquid-crystal displays (LCDs).…”

The 2T1C pixel driver circuit for mini-LED direct display has been proposed, which separates the switching transistor and the driver transistor from the same display substrate, replaces the driver transistor with n-metal oxide semiconductor (NMOS), and combines PCB substrate and thin-film transistor (TFT) substrate to improve the driving capability of the circuit. The NMOS was soldered with mini-LEDs simultaneously onto a substrate which connects to the a-Si TFT array. Two driving modes for a 32-level gray-scale display panel were investigated to compare the voltage-current and optical characteristics. The results demonstrated that the drain-driving mode is better suited for high brightness and high-power display application scenarios as it supports higher-driven currents, but the source-driving mode is more appropriate for precision gray-scale applications due to the higher current linearity of the mode.

“…Lau JH focuses on the indoor super-large special-shaped high-definition LED TV display management system, and takes the LED TV display management system optimization project design of the innovation center business lobby of the Anhui Radio and Television Bureau as the main case, and introduces the optimization of the project design plan and the content of the project implementation plan in detail. And case analysis, and the research has no actual innovation [5]. The large, medium and small screen TV LED digital display TV system designed by Jiang ZX, as long as it is supplemented by a simple peripheral control circuit design as needed, can effectively meet the large-screen TV LED display during the exhibition period, and enhance the universality of the large-screen LED display.…”
