1. Technical Field
The present invention relates to display devices, particularly, to a display device with touch control function.
2. Description of Related Art
Display devices with touch control functions are widely applied to portable electronic devices, such as mobile phones, personal digital assistants, notebooks and etc. A typical display device with touch control function includes a touch panel, a display panel, a back light module and a processing module. The touch panel, the display panel and the back light module are electronically connected to the processing module. The touch panel is positioned on the display panel. An operating signal is produced when a finger or stylus touches the touch panel, and the signal is transmitted to the processing module. The processing module processes the operating signal and sends data to the display panel and the back light module to operate. However, the touch panel is usually thin, and is directly touched by finger or stylus. Thus the touch panel may easily be scraped after repeatedly usage. Therefore, there is space for improvement within the art.
Many aspects of the display device with touch control function can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present display device, in which:
Referring to
The protective film 11 attached to the display panel 12 may be a transparent resin film, configured for protecting the display panel 12 from being scratched. Also referring to
Referring to
It is to be understood that the present display device 10 does not have conventional touch panel, so as to be more durable than the typical display device with touch control function. In addition, the present display device 10 applies magnetically sensitive elements 142 cooperating with the magnetic nib 22. If something non-magnetic accidentally touches the protective film 11, no feedback will be produced. This may reduce mistakes in operation.
It is to be further understood that even though numerous characteristics and advantages of the present embodiments have been set forth in the foregoing description, together with details of the structures and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
