The present application is the U.S. national phase entry of PCT/CN2016/074442, with an international filing date of Feb. 24, 2016, which claims the benefit of Chinese Patent Application No. 201510622900.4, filed on Sep. 25, 2015, the entire disclosures of which are incorporated herein by reference.
The present disclosure belongs to the field of liquid crystal display manufacturing technique, and relates to a terminal capable of detecting rays, an enclosure, and a method for fabricating the terminal.
Ionizing radiation refers to rays with a short wavelength, high frequency, and high energy. The ionizing radiation is divided into natural radiation and artificial radiation. The natural radiation mainly originates from natural radiation in the nature, such as cosmic rays, and rays from radioactive nuclide in the earth crust. The artificial radiation is mainly applied to medical imaging apparatuses, teaching and research institutions, nuclear reactors, non-destructive inspection. If the ionizing radiation is not properly protected, an accident which causes harm to a human body is prone to occur. Exposure to excessive radiation tends to cause cancer. Therefore, it is necessary to monitor the ionizing radiation in the environment and issue an alert timely, so as to effectively prevent harmful accidents.
Currently, a common device for measuring ionizing radiation comprises a thermoluminescence dosimeter, a film dosimeter, a glass dosimeter, a semiconductor dosimeter, or the like. A medical imaging staff, a non-destructive inspection staff, and a nuclear staff generally use the thermoluminescence dosimeter for detecting the radiation dose they are subject to during daily work. The thermoluminescence dosimeter operates in a manner in which defects in a crystal (e.g., LiF) are used to detect radiation. Under irradiation of rays, the crystal produces electrons and holes, which are captured by defects. Upon heating, the electrons escape and are recombined with holes to emit light. On basis of the intensity of the emitted light, the ray dose can be determined. Measuring radiation by the thermoluminescence dosimeter has a drawback in that the radiation dose cannot be displayed in real time. Instead, after a period of time elapses, the radiation dose can be obtained by heating. This is not suitable for real time prevention. The semiconductor dosimeter has advantages of a small volume, light weight, high sensitivity. However, the semiconductor detector is generally a professional detector, and is high in cost, which hinders its popular application.
The current mobile terminals (e.g., a smart phone, a smart watch, a tablet computer) are increasing in kinds and numbers, and have been used more frequently. It is found that the existing mobile terminals have increasing probabilities of breaking a screen during use. The reason mainly lies in that when a mobile terminal falls from a certain height, a tempered glass at its front side always tends to break. It is a hot spot in the art to make a display of the terminal apparatus “more resistant to break upon falling”. Many methods are proposed to solve this problem. For example, some panel manufacturer takes polyimide (PI) resin as a substrate to produce a non-glass panel.
