The sidewall part further includes a first sidewall not adjacent to the light source unit, a second sidewall adjacent to the light source unit, and a third receiving space surrounding the first receiving space for receiving a wire.

Liquid crystal display apparatus having particular fixing grooves and fixing protuberances in rear case

Disclosed is a liquid crystal display apparatus in which a liquid crystal display module and cases are tightly combined. At least one protuberance formed on a top chassis of the liquid crystal display module combines at least one fixing portion formed on a portion of a rear case corresponding to the at least one protuberance. Also, a fixing protuberance formed on a portion of a front case is inserted into between the liquid crystal display module and the rear case, thereby preventing the liquid crystal display module from being moved. Therefore, the liquid crystal display module and the cases are tightly combined, and productivity of the liquid crystal display apparatus can increase by reducing the number of parts demanded for fabrication of the liquid crystal display module and the cases.

A display device includes an active area and a peripheral area adjacent to at least a portion of the active area; a base layer; a backplane layer disposed on the base layer; and a light-emitting-element layer disposed on the backplane layer, and including a light emitting element. The backplane layer includes a lower backplane layer, an outer via layer disposed on the lower backplane layer, and an outer passivation layer disposed on the outer via layer. The outer passivation layer includes a first outer passivation layer exposing the outer via layer through a hole in the active area, and a second outer passivation layer not exposing the outer via layer in the peripheral area.

Multi-touch integrity sensing for capacitive touch screen

A method for multi-touch integrity sensing for a multi-touch capacitive touch screen is disclosed. By determining the integrity of touches, a distinction is identified between wanted touches, such as via a finger or stylus, and unwanted touches such as via foreign matter, errors, and the like.

Method for setting a filter coefficient for a communication system

A method for setting a filter coefficient for a communication system, which adjusts a frequency bandwidth by setting a filter coefficient of a wireless communication system over a communication network, is provided. In the method, a wireless communication system that includes a controller having a filter coefficient database and a web server, and a Digital Signal Processing device requests a filter coefficient and attribute information related to a set target frequency bandwidth from a management terminal. The wireless communication system receives the filter coefficient and the attribute information from the management terminal and stores the filter coefficient and the attribute information in the filter coefficient database. The wireless communication system sets a frequency bandwidth of the digital signal processing device as a set target frequency bandwidth based on the stored filter coefficient and the attribute information.
