Description

Technical Field

[0001] The invention relates to a handwriting board, in particular to a glass handwriting board. Background Art

[0002] Online live teaching is now very common, and when teachers teach live at home, they need to use a writing board and a camera. The camera is connected to the computer to transfer the image to the computer. If the teacher and the content on the board are to be captured clearly, a larger writing board is needed and the camera needs to be placed at a farther distance. This requires a larger teaching venue, but the space in an average family is not large, so teachers can only use a smaller writing board for live broadcasts at home, and the camera can only face the writing board. This also causes students to only see the writing board and hear the teacher's voice most of the time, but not the teacher, which reduces the interaction between teachers and students, thereby affecting the quality of teaching.

[0031] Working principle:

[0032] When teaching is required, the power socket PCB27 is connected to the power supply, the computer is connected to the USB board on the device through a USB cable, and the conjoined button 34 is clicked. The conjoined button 34 acts on the key board PCB33, the key board PCB33 acts on the functional main board PCB32, and the functional main board PCB32 acts on the fill light LED light bar 11, the fluorescent light bar 22 and the camera 41. By clicking different buttons on the conjoined button 34, the functional main board PCB32 is controlled to turn on the fill light LED light bar 11, the fluorescent light bar 22 and the camera 41, and the fluorescent light bar can also be controlled. The light strips of different colors on the transparent glass 22 change the light of different colors to meet different usage requirements; after turning on the fill light LED light strip 11, the fluorescent light strip 22 and the camera 41, the fill light LED light strip 11 located in the light strip fixed front frame 12 at this time evenly scatters the light through the light guide sheet 13 outside the light strip fixed front frame 12, so as to provide fill light for the teacher standing in front of the equipment, so that better images can be taken even in a dark environment; the teacher can use a fluorescent pen to write on the transparent glass 23, and the fluorescent light strips 22 distributed around the transparent glass 23 evenly scatter the light through the light guide glue. The light is evenly diffused to fill in the transparent glass 23, making the words written by the teacher on the transparent glass 23 clearer, and the fluorescent light bar 22 can also be adjusted to the required color of light by pressing a button; the image sensor 411 on the camera 41 at the rear end of the device can obtain the mirror image on the transparent glass 23 in front and the mirror image of the teacher, and these mirror images are processed and converted into normal images by the image processing chip 412. The normal image is transmitted to the USB interface 46 through the camera function motherboard 45, and then transmitted to the function motherboard PCB32, and then transmitted to the computer through the USB board 26. The computer uses the image output software to display the normal image. The students can normally see the words written by the teacher on the transparent glass 23 and the image of the teacher through the live broadcast software, and the teacher can also interact with the students, effectively improving the quality of live teaching; when the teaching is finished, the fill light LED light bar 11, the fluorescent light bar 22 and the camera 41 are turned off by clicking the combined button 34, and then the power supply and the USB cable connected to the computer are disconnected, and the shooting support rod 42 is rotated to fold onto the support rod 44. After folding into place, the camera 41 will be protected by the camera protective shell 48.

[0033] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
