Description

A mobile phone and a tablet computer that can be self-projected on the touch surface

technical field

The invention relates to the field of electronic equipment, in particular to a mobile phone and a tablet computer that can self-project on a touch surface.

Background technique

Touch screen technology is widely used in existing mobile phones and tablet computers. The touch screen receives a finger or a pen tool sliding on the surface of the touch screen as an input control signal, and at the same time uses the LCD screen to output image information. However, if people watch the LCD screen for a long time, the direct radiation of the LCD screen will cause dryness, vision loss and other damage to the human eyes. Especially for minors, whose eyes are not fully developed, they are more likely to be damaged by the impact of LCD screens. Existing mobile phones and tablet computers can be connected with external devices to realize the projection function, but still retain the liquid crystal display output of the touch screen, but use the projection output as another display output path, and can not be projected on the touch screen.

Contents of the invention

In order to solve the above problems, the present invention provides a mobile phone and a tablet computer that can self-project on the touch surface.

In order to achieve the above object, the technical scheme that the present invention takes is:

A mobile phone and a tablet computer that can self-project on the touch surface, including a control board of the mobile phone and the tablet computer, a touch panel installed above the control board of the mobile phone and the tablet computer, and a data transmission interface installed on one side of the control board of the mobile phone and the tablet computer And a DLP projection module that communicates with the data transmission interface. The projection area of the DLP projection module is fixed on the touch panel of the mobile phone or tablet computer and corresponds to the touch position. Connect with the DLP projection module.

Further, the data transmission interface adopts an HDMI interface, a VGA interface or a DVI interface, preferably, an HDMI interface is selected.

Further, the touch panel adopts a capacitive touch panel, including a high-definition glass fiber screen, an OCA adhesive layer, a conductive ITO panel and a substrate arranged sequentially from top to bottom, and the edge of the ITO panel is equipped with a flexible circuit board. Metal wires are arranged inside the ITO surface.

Further, the DLP projection module is a DMD-based DLP projection module, and the touch panel is used as a projection area, and is integrated with the DLP projection module on a mobile phone or a tablet computer.

The present invention has the following beneficial effects:

Compared with LCD screens, projector projection imaging is relatively less harmful to human eyes. Using projection imaging to replace liquid crystal imaging in mobile phones and tablet computers has positive significance for the eyes of people, especially minors.

The present invention retains the control operation function undertaken by the original touch screen area, cancels the liquid crystal display function of the original touch screen area; uses the original touch screen area as the projection area for projection imaging of projection modules in mobile phones and tablet computers. Because the projection module is connected with the mobile phone and the tablet computer, when the person moves the mobile phone or the tablet computer, the projection module moves together with the mobile phone and the tablet computer, thereby ensuring that the output image of the projection module can be projected on the touch surface in real time.

Detailed ways

The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

As shown in Fig. 1, a kind of mobile phone of the embodiment of the present invention can self-project on the touch surface, tablet computer, comprise mobile phone, tablet computer control motherboard 1, be installed on mobile phone, touch panel 2 above the tablet computer control motherboard 1, The data transmission interface 3 installed on one side of the control board 1 of the mobile phone and tablet computer and the DLP projection module 5 communicating with the data transmission interface 3 . Described data transmission interface 3 is connected with described DLP projection module 5 by built-in fixed support 4 of power line, signal transmission line, and the projection area of described DLP projection module 5 is fixed on the touch panel of mobile phone, panel computer and touches position correspond.
