Abstract

The invention discloses an evaporation device, an evaporation method and a display device. The evaporation device comprises a machine table used for placing a substrate, a framework and at least one mask plate. The substrate comprises a working area and a non-working area. The working area comprises a display area and a non-display area. The framework is used for installing the mask plates. The atleast one mask plate comprises the first mask plate and the second mask plate. The first mask plate is installed onto the framework and the first mask plate and the substrate are oppositely arranged.The second mask plate is installed onto the framework and the second mask plate and the substrate are oppositely arranged. The evaporation device, the evaporation method and the display device have the technical effects that a second cathode evaporated from the second mask plate is overlapped onto a first cathode evaporated from the first mask plate, and the cathodes evade a camera shooting areaunder a screen completely, so that light transmissivity of the camera shooting area is improved and the camera shooting effect is ameliorated.

Description

technical field [0001] The present invention relates to the field of display, in particular to an evaporation device, an evaporation method and a display device. Background technique [0002] In recent years, the development of the mobile terminal market has stimulated the progress of new display technologies. In order to meet the demand for large-screen display and high screen-to-body ratio of mobile terminals, the mobile phone industry has introduced the concept of full-screen in the past two years to increase the screen-to-screen ratio of mobile phone screens. In order to achieve the ideal full-screen display state, relevant practitioners around the world have carried out a lot of theoretical and practical explorations. Among them, the under-screen fingerprint recognition system has been mass-produced, and the under-screen camera and under-screen call functions are still under development. It is difficult to realize the coexistence of the real display-camera and display c...
