Abstract:
The present invention relates to a nano-diamond dispersion solution and a method for preparing the same. The method for preparing a nano-diamond dispersion solution comprises the following steps: providing a nano-diamond aggregation; mixing the nano-diamond aggregation with a metal hydroxide solution and stirring the mixture such that the nano-diamond aggregation is separated, to obtain a mixture solution; stabilizing the mixture solution such that the mixture solution is separated into a supernatant and precipitates; and extracting the supernatant and precipitates.
Abstract:
Provided is a display device. The display device includes a light guide plate, a light source disposed on a side surface of the light guide plate, a light conversion member disposed between the light source and the light guide plate, and a first adhesion member closely attached to the light guide plate and the light conversion member. An air layer between the light source and the light guide plate is removed by the first and second adhesion members to improve light incident efficient into the light guide plate.
Abstract:
Disclosed is a remote signal input system. The remote signal input system includes a transmitting apparatus for generating signal light, and a display panel having a plurality of sensors for sensing the signal light. The remote signal input system inputs a position signal to a display apparatus containing the display panel by the signal light emitted from the transmitting apparatus.
