BRIEF DESCRIPTION OF THE DRAWINGS

[0022] FIG. 1 illustrates the structure of an interactive high-clarity glass electronic whiteboard with capacitive touch sensing module according to embodiment 1 of the present invention;

[0023] FIG. 2 illustrates the structure of the capacitive touch sensing module of embodiment 1;

[0024] FIG. 3 illustrates the structure of an interactive high-clarity glass electronic whiteboard with infrared sensor module according to embodiment 2 of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

[0025] The preferred embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

Embodiment 1

[0026] As shown in FIG. 1 and FIG. 2, an interactive high-clarity glass electronic whiteboard includes a writing board body 1. The writing board body 1 includes a base board 11, an ultra-thin tempered glass 12 and a capacitive touch sensing module 13. The capacitive touch sensing module 13 is attached with a back side of the ultra-thin tempered glass 12. White ink 123 is printed on an attaching surface 121 of the ultra-thin tempered glass 12 attaching with the capacitive touch sensing module 13. A writing surface 122 of the ultra-thin tempered glass 12 is a matte surface with anti-glare treatment; a front side of the base board 11 attaches with the capacitive touch sensing module 13. A back of the base board 11 is affixed with a green board 14 for chalk writing.

[0027] Further, the capacitive touch sensing module 13 comprises a transparent plastic film 131. A front side and a back side of the transparent plastic film are provided with horizontal conductive film lines 132 and vertical conductive film lines 133 respectively.

[0028] Further, the base board 11 is an aluminum honeycomb panel. A side of the aluminum honeycomb panel that only attaches with the capacitive touch sensing module 13 is bonded with an aluminum plate 111. The green board 14 is directly affixed with the aluminum honeycomb panel.

Embodiment 2

[0029] As shown in FIG. 3, an interactive high-clarity glass electronic whiteboard includes a writing board body 10. The writing board body 10 includes a base board 101 and an ultra-thin tempered glass 102. An infrared sensor module 103 is mounted around a surface of the ultra-thin tempered glass 102. A white film 104 is attached between the ultra-thin tempered glass 102 and the base board 101. The writing surface 1021 of the ultra-thin tempered glass and a surface of the white film 104 are both matte surfaces with anti-glare treatment.

[0030] The film between the ultra-thin tempered glass and the base board of the present invention can be beige in color. By using a beige or white film as a soft non-transparent interlayer to attach with the ultra-thin tempered glass, air bubbles will not be produced, and then when the ultra-thin tempered glass is attached to the base board, covering by the non-transparent film blocks air bubbles produced in such attachment to produce a hard screen from being seen on a surface of the screen, so it is not necessary to carry out a process of removing bubbles; the white ink printed on the attaching surface of the ultra-thin tempered glass attaching with the base board directly covers the air bubbles produced in attachment. Therefore it is also not necessary to carry out a process of removing bubbles; when the back of the non-transparent interlayer attaches with the capacitive touch sensing module, the non-transparent interlayer also covers the lines on the film, so the diameter which the conductive film lines span across may be enlarged appropriately. Further, no additional blackening and hiding process is required. The non-transparent interlayer design does not only simplify the manufacturing process but also improve production efficiency.

[0031] A thickness of the ultra-thin tempered glass of the present invention is preferably 0.32 mm, thereby preventing partial superimposition of a word over its shadow and thus achieving better display effects; a frame can also be provided to surround the outer boundaries of the writing board, making the writing board better in appearance and having a higher stability; the material of the base board is not limited to the aluminum honeycomb panel. It can also be a board material which is not easy to deform and have a high degree of smoothness, such as a magnesia board or a high-density extruded board; capacitive touch sensing module may have a structure not limited to the embodiments as well. It can be an ordinary ITO conductive layer or a GG touch panel. The horizontal conductive film lines and the vertical conductive film lines are made of any one of copper, aluminum, gold, silver, and conductive carbon paste; when the present invention uses an infrared sensor module to realize the touch function, the manufacturing cost can be greatly reduced; the interactive high-clarity glass electronic whiteboard of the present invention has a light weight. It can be directly mounted on a frame and flip sides manually. It can also be mounted on a support in a rotatable manner.
