Transparent electrode is a kind of special material with good light transmittance and electrical conductivity, which is widely used in modern display technology. Its role is to conduct electricity without blocking light, thus achieving efficient power transmission and optical performance compatibility.

The most common transparent electrode material is indium tin oxide (ITO), which has high transparency and low resistance, so it is widely used in liquid crystal displays (LCDS), organic light emitting diodes (OLeds), and touch screens. Transparent electrodes are usually coated on the display substrate to transmit driving signals and control the luminous or display state of each pixel while keeping the picture clear.

With the development of display technology, people put forward higher requirements for transparent electrodes. For example, next-generation displays require flexible, ultra-thin, or bendable properties, so new transparent conductive materials such as graphene, silver nanowires, and carbon nanotubes have become research hotspots. These materials not only improve the flexibility and conductivity of transparent electrodes, but also open up possibilities for future wearable display devices and crimped screens.

Transparent electrode is one of the core technologies in the development of display, and its progress will further promote the innovation and application of display technology.
