Patent Issued for Liquid Crystal Display Module, Display Device Set Including the Same, and Method of Assembling Liquid Crystal Display Module

August 20, 2014



By a News Reporter-Staff News Editor at Journal of Engineering -- From Alexandria, Virginia, VerticalNews journalists report that a patent by the inventors Cho, Joo-Woan (Asan-si, KR); Park, Se-Ki (Suwon-si, KR); Choi, Seong-Sik (Seoul, KR), filed on March 15, 2013, was published online on August 5, 2014.

The patent's assignee for patent number 8797478 is Samsung Display Co., Ltd. (KR).

News editors obtained the following quote from the background information supplied by the inventors: "The present invention relates to a liquid crystal display ('LCD') module, a display device set including the same, and a method of assembling an LCD module, and more particularly, an LCD module capable of being simply assembled and having a small thickness, a display device set including the same, and a method of assembling an LCD module.

"A liquid crystal display ('LCD') is one of the most commonly used flat panel displays ('FPDs') and includes two substrates having electrodes formed thereon and a liquid crystal layer interposed therebetween. When a voltage is applied between the electrodes, liquid crystal molecules in the liquid crystal layer are rearranged to adjust the quantity of transmitted light.

"Since the liquid crystal molecules change the amount of transmitted light according to the direction and the intensity of an electric field to display an image, the LCD device requires light for displaying images. For example, representative examples of a light source used for the LCD device include a light-emitting diode ('LED'), a cold cathode fluorescent lamp ('CCFL'), and a flat fluorescent lamp ('FFL').

"In the related art, the LCD device adopts a side emission type in which CCFL is generally used to emit light to a side surface of a light guide plate. In the side emission type, the LCD device is manufactured manually, not automatically, in terms of its structural characteristics."

As a supplement to the background information on this patent, VerticalNews correspondents also obtained the inventors' summary information for this patent: "It has been determined herein that an assembly process of a prior art liquid crystal display ('LCD') is complicated, and takes a long time to assemble the prior art LCD device.

"An aspect of the present invention provides an LCD module that can be simply manufactured and has a small thickness.

"Another aspect of the present invention provides a display device set including the LCD module.

"Still another aspect of the present invention provides a method of assembling an LCD module.

"However, the aspects, features and advantages of the present invention are not restricted to the ones set forth herein. The above and other aspects, features and advantages of the present invention will become more apparent to one of ordinary skill in the art to which the present invention pertains by referencing a detailed description of the present invention given below.

"According to exemplar embodiments of the present invention, there is provided an LCD module including a liquid crystal panel, a mold frame provided below the liquid crystal panel and supporting the liquid crystal panel, a light guide plate provided below the mold frame, and a light source assembly coupled to an outside of the mold frame to accommodate the light guide plate therein, the light source assembly partially inserted into the mold frame, and supplying light to the light guide plate. The light source assembly includes a cover coupled to the mold frame, a printed circuit board ('PCB') provided on the cover and having a circuit pattern disposed thereon, and a plurality of point light source elements connected to the PCB.

"According to other exemplary embodiments of the present invention, there is provided a display device set including the LCD module, a set frame surrounding an edge of the LCD module, a front case provided in front of the LCD module and the set frame and having a window through which a display area of the LCD module is exposed, and a rear case coupled to rear surfaces of the LCD module and the set frame.

"According to still other exemplary embodiments of the present invention, there is provided a method of assembling an LCD module, the method including sequentially arranging optical sheets, a light guide plate, and a reflecting sheet on a rear surface of a mold frame, coupling the mold frame and a light source assembly such that the light source assembly at least partially covers the rear surface of the mold frame, turning the mold frame over and arranging a liquid crystal panel on a front surface of the mold frame, and adhering a fixing film to a boundary between the liquid crystal panel and the mold frame."
