The invention provides silica-alumina-sodium oxide glass which is suitable for a low-temperature ion exchange process and is easy to melt. The glass is suitable for chemical tempering, and comprises the following compositions in percentage by weight: 55 to 60 percent of SiO2, 0.1 to 2.5 percent of B2O3, 11 to 16 percent of Al2O3, 14 to 17 percent of Na2O, 1 to 8 percent of K2O, 0 to 8 percent of ZrO, 0 to 5 percent of CaO, 0 to 5 percent of MgO, and 0 to 1 percent of Sb2O3. The invention, by reasonably setting the compositions, reduces the manufacturing difficulty of the glass, obviously reduces the melting temperature of the glass, and is favorable for reducing energy consumption and improving the rate of finished products of products; and under the conditions that the tempering temperature of the glass is between 380 and 500 DEG C and the tempering time is between 4 and 12 hours, the surface compressive stress of the glass can reach between 610 and 1,100MPa, the depth of a stress layer can reach between 31 and 80 mu m, and the glass is strengthened and has good shock resistance. The glass has higher wear resistance, and is suitable for protective glass materials of high-grade electronic display products such as mobile phones, PDA and the like.

An ultraviolet ray-emitting element is provided in a frame-like member disposed between an apparatus module and an apparatus case by corresponding to a peripheral portion of a protective glass. A light in an ultraviolet range from the ultraviolet ray-emitting element is irradiated between the module and the protective glass. A luminescent layer to which an ultraviolet ray is irradiated emits a light.

A portable computing device is disclosed. The portable computing device can take many forms such as a laptop computer, a tablet computer, and so on. The portable computing device can include a single piece housing and a display module. The display module can include a protective top glass cover that is bonded to a plastic display frame and surrounded by a seal frame. The display module can also include a display panel and its associated circuitry suspended from the display frame below the protective glass cover. The display module is coupled to the single piece housing mounting clips in a manner that allows the display module to move relative to the single piece housing during an impact event. The plastic display frame can include inserts that provide structural support near openings in the single piece housing.

The invention discloses a method for allowing a protective film or protective glass to be in communication with a mobile phone. The method comprises the steps that a user downloads and installs a mobile phone APP according to mobile phone model network recognition; one or more APP hidden icons are planted into the edge of a display window or a region without operation icons of a mobile phone touch screen by the mobile phone APP; the protective film or the protective glass is attached to the mobile phone touch screen; touch keys are manufactured on the non-touch-response part at the upper end or the lower end of the mobile phone touch screen or the protective film or the protective glass; a certain touch key is operated, so that the changes of capacitive sensing at the APP hidden icons of the touch screen are caused; due to CPU data input and output, the mobile phone APP can be quickly and conveniently waken up or exit. According to the method, besides increasing the traditional use such as scraping resistance and fouling prevention of the mobile phone for the user, through smart phone system development, the user can conveniently download APP settings as needed by himself / herself and operate the region, which originally does not have a touch response, outside the display window of the mobile phone to quickly achieve wake-up or exit of the commonly used and required APP. In this way, the application region of the mobile phone is enlarged, and experience and playability are improved.

A device used for detecting touch of infrared touch screen uses foil gauge set at edge region of protective glass on touch screen as mechanical transducer to realize said detection. It is featured as connecting detected electromechanical signal to I / O interface of micro-controller after said signal is processed by signal processing circuit and applying said signal as necessary condition for judging occurrence of touch event in order to raise touch screen judgment accuracy on touch event.

An element, particularly a transparent element, including at least one glass element, configured as a protective glass against ionizing radiation and / or UV radiation, wherein at least a portion of the surface of the glass element is covered by a film that includes a substance that can be switched into at least two states.
