Abstract: A double-layer cholesteric liquid crystal display and its manufacturing method are disclosed. The double-layer cholesteric liquid crystal display includes three transparent substrates, two opposing electrode layers, two cholesteric liquid crystal layers, and a first light-absorbing layer. Additionally, the double-layer cholesteric liquid crystal display incorporates two drive ICs and a second light-absorbing layer. The two drive ICs can be positioned either on the same side or on opposite sides within the non-display area of the double-layer cholesteric liquid crystal display. Furthermore, the first cholesteric liquid crystal layer exhibits a first color light, and the second cholesteric liquid crystal layer exhibits a second color light, where the colors are selected as contrasting colors. Additionally, the two cholesteric liquid crystal layers possess mutually opposite optical rotary properties.

Abstract: A spliced reflective display includes multiple display devices, a front light guide plate, and at least one light source. Among the multiple display devices, one display device is joined side-by-side with another to form an adjacent joint. The front light guide plate is affixed above the multiple display devices and is close to the display side. It has a top surface near the display side and includes an optical structure. The at least one light source is positioned at the side of the front light guide plate, and light therefrom reflects off the top surface of the front light guide plate onto the multiple display devices, and the reflected light from the display devices forms image light that is directed towards the display side to produce an image. The optical structure directs the path of the image light to obscure the adjacent joint from being visible on the display side.

Abstract: A temperature measuring device includes a local terminal and a measuring element installed at a predetermined distance from the local terminal. The local terminal includes a first measuring unit for measuring a first human body temperature, a signal processing unit for receiving and converting the first human body temperature, a display unit coupled to the signal processing unit for displaying the converted first human body temperature, and a first interface unit coupled to the signal processing unit.

Abstract: A temperature measuring device includes a main body and a measuring element installed at a predetermined distance from the main body. The main body includes a first measuring unit for measuring a first body temperature, a signal processing unit for receiving and converting the first body temperature, a display unit coupled to the signal processing unit for displaying the converted first body temperature, and a first interface unit coupled to the signal processing unit. The measuring element includes a second interface unit and a second measuring unit coupled to the second interface unit for measuring a second body temperature and transmitting the second body temperature via the second interface unit to the first interface unit, which sends the second body temperature to the signal processing unit, which converts the second body temperature and transmits the converted second body temperature to the display unit, which displays the converted second body temperature.

Abstract: A temperature sensing device is proposed. The device includes a body and at least a temperature sensing member separated from the body by a predetermined distance. The body includes a displaying unit and a first interface unit, and the temperature sensing member is connected to the first interface unit of the body via a second interface unit. The temperature sensing member is set on a test subject using a detachable fixing unit and a measuring unit is used to measure the body temperature of the test subject. The measurement is received and processed by a signal processing unit, and subsequently transmitted to and displayed in the displaying unit. The signal processing unit can also be provided in the body or the temperature sensing member for converting and processing a temperature signal.
