20150370108 | DISPLAY PANEL AND DISPLAY DEVICE - The invention discloses a display panel which includes a liquid crystal cell; a first polarizer, arranged on a light inputting side of the liquid crystal cell; and a second polarizer, a polarization direction of which is perpendicular to a polarization direction of the first polarizer, wherein the second polarizer is detachably arranged on a light outputting side of the liquid crystal cell and is able to cover a valid display region of the display panel. The invention also discloses a display device which includes above display panel and polarized glasses. When there are no confidential files, the second polarizer covers a valid display region of display panel; when there are confidential files to be processed, the second polarizer is removed from the valid display region of display panel. Therefore, it is possible to effectively improve the availability of the display panel and the display device having said display panel. | 12-24-2015 |
20150370127 | LIGHTING SYSTEM, LIGHTING DEVICE AND RECEIVING DEVICE - The general inventive concepts provide a lighting system, a light device and a receiving device. The lighting device applies a liquid crystal display panel as a luminaire, the liquid crystal display panel has a first polarizer only on a light input side. The receiving device comprises a second polarizer and a magnifying component. The second polarizer is used for polarization-analyzing an emitted light, which is emitted from the liquid crystal display panel and carries confidential information. Light passes through the first polarizer and becomes linearly polarized light, which linearly polarized light is emitted after passing through the liquid crystal display panel. The confidential information carried therein cannot be identified by the naked eye. Therefore, the human eye regards it as white light, the lighting device can thus be used as a lighting luminaire. However, when watching the lighting device through the receiving device, the confidential information displayed by the liquid crystal display panel can be seen clearly. | 12-24-2015 |
20150370128 | Illumination Device, Dedicated Glasses, Analyzer and Illumination System - An illumination device, dedicated glasses thereof, an analyzer thereof and an illumination system are provided. The illumination device includes a support member and a liquid crystal display panel mounted on the support member. The liquid crystal display panel includes a display area and a light emitting area, the liquid crystal display panel is provided with a first polarization sheet at its light incoming side in areas corresponding to the display area and the light emitting area, and is provided with a second polarization sheet at its light outgoing side only in area corresponding to the display area. The illumination device emits white light and can be used as an ordinary lamp because its light emitting area cannot be observed in the naked eye state, and when observed through the dedicated glasses or the analyzer, the content of the secret information displayed by the liquid crystal display panel can be seen. | 12-24-2015 |
