Abstract: The present disclosure provides a pixel structure, a method of driving the same and a display device. The pixel structure includes gate lines, data lines, and a plurality of subpixels arranged in an array form. Subpixels in each row correspond to two gate lines. Each data line corresponds to the subpixels in two adjacent columns, and each data line is arranged between the two adjacent columns of subpixels. Among the subpixels in each row, three adjacent subpixels are in different colors and forms a complete pixel unit. Among the subpixels in each column, three adjacent subpixels are in different colors and forms the complete pixel unit. Among the subpixels in two adjacent columns, the subpixels in two adjacent rows form two complete pixel units each including three subpixels, and two of the three subpixels are shared by the two pixel unit.

Abstract: The present disclosure provides an LED assembly, a light source, and a liquid crystal display device. The LED assembly includes: a substrate; a plurality of blue LED chips which are disposed on the substrate at intervals and have different emission wavelengths; a white light phosphor layer which is disposed on the substrate and covers the plurality of blue LED chips; and a sealing frame which is disposed on the substrate and is configured to encapsulate the plurality of blue LED chips and the white light phosphor layer. The LED assembly encapsulates the blue LED chips having different emission wavelengths together, which can avoid LED mixing from an LED encapsulation source, thereby saving cost. Moreover, problems such as nonuniform images and chromatic aberration are basically avoided when the LED assembly is applied to an LCD module.
