AI Technical Summary
Traditional LCD displays suffer from image quality degradation and high complexity in small pixel pitch designs. Digital pixel circuits struggle to maintain sufficient charge when pixel pitch is below 6μm, and the large number of transistors required by traditional digital pixel circuits increases complexity.
It employs a dual-voltage system and a level-shifting system, including multiple memory storage units and level-shifting circuits, utilizes two transistors to achieve voltage conversion, and combines a self-adjusting transistor bias circuit and an on-chip test array to optimize transistor leakage characteristics.
It achieves image quality maintenance with extremely small pixel pitch, while reducing the complexity of pixel circuits and the number of transistors, thus improving operation speed and efficiency.
