Abstract

There are provided a thin transformer capable of being used in a thin display device such as a liquid crystal display (LCD) device, a light emitting diode (LED) device, and a flat panel display device including the thin transformer. The transformer includes a bobbin part including inner and outer bobbins each including a pipe shaped body part having a though-hole formed in an inner portion thereof and a flange part protruding outwardly from both ends of the body part; coils respectively wound around the inner and outer bobbins, and a core electromagnetically coupled to the coils to thereby form a magnetic path, wherein the outer bobbin includes a support part formed at the flange part formed at an upper end of the body part of the outer bobbin so as to cover a portion of the through-hole, and the inner bobbin is coupled to the outer bobbin while having one end supported by the support part.

Description

[0001] This application is a divisional application of the invention patent application "Transformer and Flat Panel Display Device Equipped with the Transformer" with application number 201110191334.8 filed on July 4, 2011. technical field [0002] The present invention relates to a thin transformer that can be applied to thin display devices such as LCD display devices, LED display devices, and the like. Background technique [0003] In recent years, in the display industry, a new technology suitable for multimedia systems such as high resolution and large screens - Flat Panel Display (FPD: Flat Panel Display) instead of CRT (Cathode Ray Tube: Cathode Ray Tube) has attracted attention. [0004] In particular, among large displays, thin displays such as LCD (Liquid Crystal Display) TV and PDP (Plasma Display Panel) TV are attracting attention, and it is expected that they will continue to attract attention in terms of price and market in the future. [0005] Among them, LCD ...
