Abstract

The invention relates to a light excitation display device and system, and relates to the technical field of light excitation display. According to the main technical scheme, the light excitation display device comprises a first substrate, a first transparent electrode layer, a photoluminescence layer, a vacuum layer, a second electrode layer, a second substrate and a control apparatus; the firstsubstrate, the fist transparent electrode layer, the photoluminescence layer, the vacuum layer, the second electrode layer and the second substrate are stacked in sequence; the control apparatus is connected with the first transparent electrode layer and the second electrode layer separately; when excitation light of a preset wavelength is irradiated on the photoluminescence layer, the irradiatedposition of the photoluminescence layer can be excited and is in the luminance state; the control device enables an electric field to be generated between the first transparent electrode layer and thesecond electrode layer, and the position, in the luminance state, of the photoluminescence layer is quenched. On the condition that the light excitation display device is not supplied with power, writing display can be achieved under the irradiation of the excitation light, the problem that an LED writing display device is high in energy consumption is solved, and the problem that adverse influence is generated on the vision of a user due to long-time viewing is also solved.

Description

technical field [0001] The present invention relates to the technical field of optical excitation display, in particular to an optical excitation display device and an optical excitation display system. Background technique [0002] With the development of science and technology, teachers' teaching methods are becoming more and more diversified and intelligent. However, due to the randomness of teaching content and the ability to play in class, the traditional blackboard has been used. However, the use of traditional chalk has brought dust pollution to the classroom environment, causing harm to the health of teachers and students. [0003] Therefore, in order to improve the teaching environment and realize the intelligence of teaching, an LCD (liquid crystal display) display writing device is used as a blackboard in the prior art. [0004] However, the existing LCD display writing device not only consumes a lot of energy, but also has an adverse effect on the user's eyesigh...
