Problems solved by technology

However, the current LED arrays based on inorganic semiconductor materials do not have transparency, that is, they cannot display the background or objects behind the screen. The main reason is that the electrode materials and substrates used in traditional LED arrays do not have transparency.

Abstract

The invention relates to a light emitting diode (LED) micro-array transparent display apparatus. The apparatus comprises a transparent base board, a drive module and a transparent inorganic semiconductor LED micro-array that are arranged on the transparent base board. The drive module and the transparent inorganic semiconductor LED micro-array are electrically connected. Each LED chip of the transparent inorganic semiconductor LED micro-array can give out light from the front or a back transparent substrate or both the front and the back. The apparatus has high transparency and a good transparent display function, can display content that is programmable to some extent, and has flexible functions; the transparent display apparatus has a small size and light weight, meets the requirement of wearable devices on display, and is light and portable; in addition, the transparent display apparatus also has the advantages of high brightness, reliability and resolution and long service life, thereby bringing good transparent display experience; and the transparent display apparatus is realized through a standard semiconductor technology, is simple to prepare, and can be produced in a large scale.

Description

technical field [0001] The invention relates to the technical field of LED-based micro-displays, in particular to a LED micro-array transparent display device. Background technique [0002] Transparent display is a new generation of display technology that can display the background (object) behind the screen in addition to the basic display function. Its application fields include portable electronic consumer products, navigation equipment, collimators, helmet displays, Shop windows, information bulletin boards, etc., including Samsung and many other panel manufacturers are conducting research and development of transparent display technology. At present, conceptual transparent display products based on LCD or OLED have appeared in the market, but they have disadvantages such as high cost, low display brightness, and low transparency (30-40% transmittance). In addition, micro-display technology based on high-brightness, inorganic semiconductor material LED arrays (such as ...
