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.

“…The feature of active-matrix drive is that each Micro-LED pixel has an independent driving circuit, and the driving current is provided by the driving transistor [3]. There are many ways of active-matrix drive, among which the most common is the dual transistor single capacitor (2T1C) circuit [4]. As shown in Fig.…”

With the human stepping into the information society and the rapid increase of information, various display facilities and display devices are getting unprecedented development. In the display industry, Micro-LED has become the focus of development because it has the advantages of both traditional LED and small size, and can achieve extremely high PPI. However, it is precisely because of its small size, in order to drive Micro-LED display, it is particularly important to design a separate driver circuit that meets its characteristics. In this paper, different structures of pixel drivers in Micro-LED display driver circuits are studied. By comparing DRAM and SRAM structures, the performance of pixel driver under different frequency conditions is analyzed. This paper introduces and analyzes the circuit structure and design flow of various pixel drivers. Simulation is carried out by Cadence software, and its actual performance is verified by taping out.
