Abstract: A display panel and a liquid crystal display are disclosed. The display panel includes an upper polarizer, a lower polarizer, a first substrate and a second substrate disposed oppositely between the upper polarizer and the lower substrate, a liquid crystal layer disposed between the first substrate and the second substrate, a quantum dot layer disposed at a side of the second substrate which is far away from the liquid crystal layer, and a protection layer for protecting the quantum dot layer, disposed between the quantum dot layer and the lower polarizer. The quantum dot layer is disposed at a side of the second substrate far away from the liquid crystal layer, and the protection layer is disposed between the quantum dot layer and the lower polarizer. The protection layer is used for preventing the quantum dot layer from being oxidized. The color gamut of LCD can be increased.

Abstract: The present invention proposes an illuminating device having a quantum dot tube. The illuminating device includes: a transparent tubular encapsulation device including a light incident surface and a light emergent surface and a quantum dot. Bumps and grooves are disposed on the light incident surface and/or the emergent surface at intervals. The quantum dot is encapsulated in the transparent tubular encapsulation device. When an excitement light shines the quantum dot, the quantum dot is excited to emit light through the light incident surface. By using the illuminating device, light cannot leak from the gaps among the LEDs and the QDs and among the QDs and the LGPs, which is good for enhancing light availability. Additionally, the present invention also proposes a backlight module and a liquid crystal display using the illuminating device having the quantum dot tube.

Abstract: The disclosure is related to a backlight module comprising a light guide plate, a light source assembly and a frame. The frame surrounds the light guide plate. The light source assembly is arranged between the light incident surface of the light guide plate and the frame. The light source assembly comprises a substrate, a light emitting body and a transparent body. The transparent body packages the light emitting body on the substrate. The outer surface of the transparent body facing the light emitting body is a light emitting surface having a groove formed thereon facing the light incident surface of the light guide plate. The groove enables the light emitted from the transparent body to congest toward the direction of the center of the light guide plate to increase the optical coupling efficient of the backlight module. The disclosure further provides a liquid crystal display device.

Abstract: A reflective sheet is provided, comprising a base layer, a reflecting layer coated on the base layer, and a scattering layer coated on a side of the reflecting layer that faces away from the base layer. Emergent light from such a reflective sheet is more uniform, whereby quality of an image displayed on a display device using said reflective sheet is improved.
