Abstract

The invention discloses a flexible display device based on an MZI structure and application thereof. The display device comprises a laser unit, a flexible substrate, an MZI structure and output gratings, wherein the MZI structure and the output gratings are arranged on the first surface of the flexible substrate; the laser unit is used for generating laser, and the laser is emitted into the MZI structure; the MZI structure comprises a plurality of MZI units arranged in an array, and adjacent MZI units in each row are connected through a transmission waveguide; and the MZI units are in one-to-one correspondence with the output gratings and are used for coupling the laser with the wavelength matched with the MZI units and transmitting the coupled laser to the output gratings for display. According to the invention, the laser is used as a light source, and the MZI structure arranged on the flexible substrate is combined to realize the selection and transmission of the laser, so that the display device has the advantages of wide display color gamut, long service life, high integration level, high luminous efficiency, low cost and the like, and is particularly suitable for batch production.

Description

technical field [0001] The invention discloses a flexible display device based on an MZI structure and its application in a multimedia resource playing system, belonging to the technical field of display devices. Background technique [0002] The traditional display device is a liquid crystal display (Liquid Crystal Display, referred to as LCD), which is to place a liquid crystal cell between two parallel glass substrates, a thin film transistor (Thin Film Transistor, referred to as TFT) is installed on the glass of the lower substrate, and a thin film transistor (TFT) is placed on the glass of the upper substrate. Set the color filter, control the rotation direction of the liquid crystal molecules through the signal and voltage changes on the TFT, and control whether the polarized light of each pixel is emitted or not, so as to achieve the purpose of display. [0003] However, with the development of society, people put forward higher requirements for display devices, such ...
