1. Precise helmsman of pixels: realizing active matrix control The core role of TFT is to equip each pixel with an independent “electronic switch”. Imagine millions of pixels on a mobile phone screen: traditional passive matrix LCDs have difficulty in independently and accurately controlling each pixel, resulting in slow response and high crosstalk. TFT is […]
1.Structural cornerstone: the dance of precision “sandwich” and electron holes The essence of OLED is an organic semiconductor device made of multi-layer functional films precisely stacked: Substrate: As the “foundation” of physical support, flexible polyimide (PI) or rigid glass is commonly used. Anode (such as indium tin oxide ITO): a transparent conductor that injects holes (positive […]
1. Technology-driven nature: the gap between passive and active Traditional LCDs (often referring to passive matrix screens such as TN/VA) rely on external voltage to slowly drive the entire row/column of pixels. TFT-LCD integrates micro-thin film transistors as independent switches at each pixel to achieve precise and fast charge control. The National Institute of Standards […]
1. Molecular reconstruction of glass substrate Corning Gorilla Glass uses the ion exchange process (Ion Exchange Process) to replace sodium ions on the surface of the glass with potassium ions at a high temperature of 680°C, forming a compressive stress layer with a depth of 40 microns. This technology, certified by the American Institute of […]
