Abstract: A writing device includes a display panel, a stylus, a transparent first electrode layer and a second electrode layer. The display panel includes a displaying layer and a first light source. The displaying layer consists essentially of a photochromic material reversibly transformable between a first state of an electroluminescent material, and a second state of a non-electroluminescent material. The first light source is configured for emitting light to the displaying layer to transform the displaying layer into the second state. The stylus includes a second light source configured for emitting light to illuminate portions of the displaying layer, thus transforming the illuminated portions of the displaying layer into the first state. The first and second electrode layers attached on opposite sides of the displaying layer are configured to excite the illuminated portions of the displaying layer in the first state to emit light.

Abstract: The backlight module includes a light source, a diffusion plate, a substrate and a reflector. The diffusion plate has a light incident surface and a light emitting surface at two opposite sides. The reflector is positioned on the light incident surface and faces the light source. The substrate includes an aspherical surface, a reflective film formed on the aspherical surface, and a recess defined in the aspherical surface. The reflective film faces the light incident surface. The light source is received in the recess. Light emitted from the light source is reflected to the reflective film by the reflector, then reflected to the light incident surface of the diffusion plate, and exits from the light emitting surface of the diffusion plate.
