Problems solved by technology
The color scanner set according to the above principles is large in size and expensive, and it is not convenient to use, and cannot meet the requirements of anytime and anywhere.
[0003] In addition, although the image file of the document can also be obtained by taking pictures with a mobile phone or a camera, the image file obtained by this method cannot be guaranteed to be equal in proportion to the document, and the image file usually cannot meet the high-quality display requirements
[0004] Therefore, the prior art lacks a scanning device that can realize equal-scale scanning of documents and is easy to use

Embodiment Construction
[0031] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0032] The scanning screen described in the specific embodiment of the present invention emits irradiating light to the document to be scanned through the light-emitting layer arranged opposite to the document to be scanned, and a light-transmitting part is arranged on the light-emitting layer, and the reflected light reflected by the document to be scanned can pass through the light-transmitting part Afterwards, it is transmitted to the optical signal receiving layer opposite to the light-emitting layer, and the light intensity of the reflected light received by the optical signal receiving layer is different by using the graphics of different colors on the document to be scanned to absorb the light differently, so that the document to be scanned can be d...

Embodiments of the invention provide a scanning screen and a scanning device. The scanning screen includes: a light emitting layer and an optical signal receiving layer, wherein the light emitting layer comprises a plurality of light emitting units arranged in an array, each light emitting unit is provided with a light transmitting portion, the light emitted from each light emitting unit is emitted to a document to be scanned that is disposed opposite to the light emitting layer, a reflected light transmitted to the light emitting layer after being reflected by the document to be scanned can be emitted through the light transmitting portion; the optical signal receiving layer is opposite to the light emitting layer, located on the opposite side of the light emitting layer on which the document to be scanned is disposed, and used for receiving the reflected light emitted through the light transmitting portion and obtaining a light strong signal of the reflected light. The scanning screen is capable of realizing close-range illumination scanning of the document to be scanned and ensuring the proportional scanning requirement of the document. The scanning screen is simple in structure, easy to implement, and capable of effectively meeting the convenient requirement of the document.
Description
technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a scanning screen and scanning equipment. Background technique [0002] Currently, the image file of the document can be obtained by scanning with a copier or a scanner. Such as figure 1 It is a schematic diagram of the principle of the prior art color scanner. A light source is installed in the color scanner, and the light source irradiates the document 1 to be scanned, and the document 1 to be scanned reflects the light emitted by the light source, and the reflected light passes through the color filter and is transmitted to the optical sensor, and the optical signal is converted from analog to digital by the optical sensor converted into a digital signal, the digital signal is converted into an image file after being processed by a processor such as an interface, and the image file of the document 1 to be scanned is obtained. The color scanner set according to ...
