An LCD projector is a type of video projector for displaying video, images or computer data on a screen or other flat surface. It is a modern equivalent of the slide projector or overhead projector .
This list includes LCD, OLED and microLED display manufacturers. LCD uses a liquid crystal that reacts to an electric current blocking light or allowing it to pass through the panel, whereas OLED/microLED displays consist of electroluminescent organic/inorganic materials that generate light when a current is passed through the material.
LCoS projectors have continued to evolve, with manufacturers introducing features like 4K resolution and HDR (High Dynamic Range) support. LCoS projectors are now available at a range of price points, from affordable models for home theater use to high-end professional models used in commercial installations.
Small LCD screens are common in LCD projectors and portable consumer devices such as digital cameras, watches, calculators, and mobile telephones, including smartphones. LCD screens have replaced heavy, bulky and less energy-efficient cathode-ray tube (CRT) displays in nearly all applications since the late 2000s to the early 2010s.
This led to Japan launching an LCD industry, which developed larger-size LCDs, including TFT computer monitors and LCD televisions. Epson developed the 3LCD projection technology in the 1980s, and licensed it for use in projectors in 1988. Epson's VPJ-700, released in January 1989, was the world's first compact, full-color LCD projector.
A projector or image projector is an optical device that projects an image (or moving images) onto a surface, commonly a projection screen. Most projectors create an image by shining a light through a small transparent lens , but some newer types of projectors can project the image directly, by using lasers .
In 2021, Jade Bird Display and Vuzix have entered a Joint manufacturing agreement for making microLED based projectors for smart glasses and augmented reality glasses [93] At Touch Taiwan 2019 on September 4, 2019, AU Optronics demonstrated a 12.1-inch (31 cm) microLED display and indicated that microLED was 1–2 years from mass ...
It employs a transparent conductive oxide as a heater that can quickly change the pixels. The pixels are 100 times thinner than liquid crystal. Response times are under 1 millisecond. They claim that the metasurface array could replace the liquid crystal layer in today's displays, eliminating the need for production technology. [25]
