Description

Technical Field

[0001] The present application relates to the technical field of display devices, and in particular to a smart writing board with ink display function. Background Art

[0002] The electronic ink screen is a screen that does not emit light itself but relies on external reflections to achieve display effects. Its display effect is very similar to that of paper materials, so it can be compared to the experience of reading paper materials. The electronic ink screen is composed of many microcapsules, each of which contains multiple black particles and multiple white particles, both of which carry opposite charges. When black content needs to be displayed on the screen, the black particles are driven by voltage to move upward to the top of the screen (that is, move from the bottom to the screen). When white content is displayed, the white particles are driven by voltage to move upward to the top of the screen (that is, move from the bottom to the screen). Traditional ink screen display devices usually use a stylus as an input auxiliary tool, and are equipped with a matching protective cover for protection.

[0003] In the prior art, a Chinese utility model patent with authorization announcement number CN216212128U discloses "an ink screen display device", including a shell, a device host, a camera component, a writing pen and a protective cover; the device host includes an ink screen and a main board, the edges of the ink screen are embedded in the shell, and the main board is located between the ink screen and the shell; the shell is provided with a camera through hole, the camera component is arranged in the shell and is arranged toward the camera through hole; the writing pen is detachably fixed to the edge of the shell; the protective cover is fixed to the shell, and movably covers the writing pen and the outside of the ink screen.

[0004] Including the ink screen display device of the prior art as mentioned above, although it has a storage function, it is unable to adjust the tilt angle in multiple directions during use. It is inconvenient to use because it requires the use of other tools or direct hand support of the electronic ink screen.

[0005] In order to solve the above problems, this application proposes a smart writing board with ink display function. Utility Model Content
