Abstract

The invention provides a display device, which comprises a first display instrument with a transmittance type first display unit and a second display instrument with a second display unit, wherein a first region occupied by the first display unit in the first display instrument and a second region occupied by the second display unit in the second display instrument are partially superposed; when the first display unit is in a light-ray transmittance first state, the second display unit is the display unit of the display device; and when the first display unit is in a light-ray non-transmittance second state, the first display unit is the display unit of the display device. According to the scheme, any one of the first display instrument and the second display instrument can independently display pictures without interference; and a user can randomly switch the two display instruments to adapt to the own requirement.

Description

technical field [0001] The present invention relates to the display field, in particular to a display device. Background technique [0002] With the advent of the information age, the wide application of digital media platforms such as personal computers and the Internet makes the display as a window for man-machine information exchange play an increasingly important role. The traditional cathode ray tube display (CRT) is gradually being replaced by flat panel display (FPD), and thin, flexible, low driving voltage and low power consumption have become the development direction of flat panel display technology. Compared with the existing electronic display technology, traditional paper still has some irreplaceable advantages, such as high contrast, high resolution, light, thin, portable, flexible, and less prone to visual fatigue. E-paper technology is such a display technology that achieves comfortable reading like paper, ultra-thin, light, bendable, and ultra-low power con...
