Embodiment 1

[0037] see figure 1 , the arrows in the figure indicate the direction of light propagation, and the same is true for the following drawings. A display device with a scanning and recording function provided in Embodiment 1 of the present application includes: a display panel 1, and a display panel located in the frame area of ​​the display panel 1. Scanning component 2 (such as figure 1 shown in the dotted box).

[0038] Wherein, the frame area refers to the area around the display panel 1 in the above-mentioned display device with scanning and recording function, for example, as figure 1 As shown, it is located below the display panel 1.

[0039] The display panel 1 can be any type of display panel, such as a liquid crystal display panel (LCD), an organic electroluminescence display panel (OLED), an electrophoretic display panel, a cathode ray tube display panel, a plasma display panel, and the like.

[0040] Such as figure 1 As shown, the scanning component 2 includes: a ...

Embodiment 2

[0051] see image 3 , a display device with a scanning input function provided in Embodiment 2 of the present application is similar to a display device with a scanning input function provided in Embodiment 1 of the present application. different parts.

[0052] Embodiment 2 of the present application provides a display device with scanning input function, such as image 3 As shown, the scanning assembly 2 may further include: a slidable shading plate 26; the incident light source 24 and the shading plate 26 are arranged in sequence along the light emitting direction of the display panel 1, and are used to block the light emitting from the incident light source 24 along the display panel 1 during the non-scanning period. Direction of light emitted. Wherein, the light shielding plate 26 is located on a side of the light guide unit 21 away from the incident light source 24 .

Embodiment 3

[0054] see Figure 4 , the display device with scanning input function provided in the third embodiment of the present application is similar to the display device with the scanning input function provided in the first embodiment of the application, the same parts will not be repeated here, and only the description will be given below different parts.

[0055] Embodiment 3 of the present application provides a display device with scanning input function, such as Figure 4 As shown, the scanning assembly 2 can also include: a beam splitter 28 arranged on the optical path between the scanning object 25 and the focusing lens group 22; the image sensor group 23 includes three rows of image sensors 231 distributed in an array; each row of image sensors 231 is used to receive an optical signal of one color among optical signals of red, green, and blue. Among them, the image sensor 231R ( Figure 5 Only one is shown in ) for receiving the red light signal, the image sensor 231G ( ...

Abstract

The present invention provides a display apparatus with scanning and enrolling functions. The display apparatus integrates scanning, enrolling and displaying. The display apparatus with scanning and enrolling functions comprises a display panel, and also comprises scanning components in the frame region of the display panel.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display device with a scanning and recording function. Background technique [0002] A display is usually also called a monitor. A display is an input and output (I / O) device belonging to a computer. It is a device that displays certain electronic files on the screen through a specific transmission device and then reflects them to the human eye. Show tools. [0003] In general, according to different manufacturing materials, displays can be divided into: Cathode Ray Tube Display (CRT), Plasma Display (PDP), Liquid Crystal Display (LCD) and so on. [0004] Displays currently on the market usually only have a display function, and when documents need to be scanned, a scanner is generally used to scan and record them into the computer. When it is necessary to display the scanned document (that is, the document after scanning and recording), it is necessary to transmit...
