The invention discloses a liquid crystal display. The liquid crystal display is characterized in that quantum dot materials are doped in a color resisting layer so that quantum dots are motivated by back lights to form lights with definite spectrum, and lights with different polarization states selectively penetrate through an anisotropic polarization layer prepared by organic dye molecules to obtain linear polarization lights. According to the liquid crystal display, the light-leaking problem caused by changing the light polarization states under the quantum dot materials can be effectively solved, the contrast ratio is increased, and the upper or lower polarizer can be replaced by the polarization layer; thus one polarization pasting process is omitted, the manufacturing process is simplified, the cost is saved, and the polarization effect can be better realized.

The invention provides an LED packaged piece and a manufacturing method of the LED packaged piece. The LED packaged piece comprises a first support (10), a plurality of LED elements (20), a packaging adhesive (30) and a quantum dot bar (40). The first support (10) comprises a PCB (12) and four side walls (14) defining an accommodating space (18). The LED elements (20) are installed on the PCB (12) and are electrically connected with the PCB (12). The packaging adhesive (30) is filled into the accommodating space (18). Four installing parts (16) are arranged at the upper ends of the four side walls (14) respectively, and the quantum dot bar (40) is installed on the installing parts (16) and located above the packaging adhesive (30). The first support (10), the LED elements (20) and the quantum dot bar (40) are integrally packaged so as to be fixedly combined together.

The invention discloses a negative phototropic module structure. It comprises a shaped body glue frame and light leading plate, a light leading plate glue inlet point on one side of the glue frame, an anti-dazzle film, and a reflecting plate. The negative phototropic module uses the extension of the anti-dazzle film or the reflecting plate to cover the light leading plate glue inlet point so that the light can not be leaked by the light leading plate glue inlet point to generate the dark field.

The invention discloses a touch screen and a touch display electronic device. The touch screen comprises a substrate, an auxiliary electrode layer, a common electrode layer and a routing layer, wherein the auxiliary electrode layer, the common electrode layer and the routing layer are arranged on the same side of the substrate, and the common electrode layer and the routing layer are oppositely arranged in the direction perpendicular to the substrate. The common electrode layer comprises a plurality of common electrode blocks which are the same. Each common electrode block comprises a center electrode and a sawtooth electrode electrically connected with the center electrode. The opposite sawtooth electrodes of every two adjacent common electrodes are nested. The routing layer comprises a plurality of first wires electrically and correspondingly connected with the common electrode blocks in a one-to-one mode. The auxiliary electrode layer comprises a plurality of auxiliary electrode blocks. The sawtooth electrodes adjacent to the edge of the substrate and the auxiliary electrode blocks are nested. When the common electrode blocks input common voltage signals for image display control, the auxiliary electrode blocks input common voltage signals. The touch screen improves the touch detection precision, and prevents the problems of visibility of edge images and light leakage of pixel electrodes near to the edge of the substrate.
