However, when a person views the liquid crystal screen for a long time, direct radiation of the liquid crystal screen may cause damage such as dryness, visual deterioration, etc. to eyes of the person. Especially for minors, eyes are not fully developed, and are more easily damaged by the influence of a liquid crystal screen. The existing mobile phone and tablet personal computer can be externally connected with equipment to realize the projection function, but still keep the liquid crystal display output of the touch screen, only take the projection output as another display output way, and can not be projected on the touch screen.
Disclosure of Invention
In order to solve the problems, the invention provides a mobile phone and a tablet personal computer which can be self-projected on a touch surface.
In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:
the utility model provides a but self-projection is cell-phone, panel computer on the touch surface, includes cell-phone, panel computer control mainboard, installs the touch panel in cell-phone, panel computer control mainboard top, installs at the data transmission interface of cell-phone, panel computer control mainboard one side and with the DLP projection module that data transmission interface realized the communication, the projection area of DLP projection module is fixed on the touch panel of cell-phone, panel computer and corresponds with the touch position, the data transmission interface through built-in have power cord, signal transmission line's fixed bolster with DLP projection module links to each other.
Further, the data transmission interface adopts an HDMI interface, a VGA interface or a DVI interface, and preferably, an HDMI interface is selected.
Further, the touch panel adopts capacitive touch panel, includes Gao Qingbo fine curtain, OCA glue film, the ITO panel and the base plate that have electric conductivity that set gradually from last down, ITO panel edge is furnished with flexible circuit board, the inside wire that is furnished with of ITO face.
Further, the DLP projection module is a DMD-based DLP projection module, and the touch panel is integrated with the DLP projection module on a mobile phone or a tablet computer as a projection area.
The invention has the following beneficial effects:
compared with a liquid crystal screen, the projection imaging of the projector has relatively less damage to human eyes, and the projection imaging is used for replacing the liquid crystal imaging in a mobile phone and a tablet computer, so that the projection imaging has positive significance for eyes of people, especially minors.
The invention reserves the control operation function born by the original touch screen area and cancels the liquid crystal display function of the original touch screen area; and taking the original touch screen area as a projection area for projection imaging of a projection module in the mobile phone and the tablet personal computer. Because the projection module is connected with the mobile phone and the tablet personal computer, when a person moves the mobile phone and the tablet personal computer, the projection module moves together with the mobile phone and the tablet personal computer, so that the output image of the projection module can be projected on the touch surface in real time.
