Embodiment Construction

[0023] Preferred embodiments of the invention will now be described in detail, examples of which are illustrated in the accompanying drawings.

[0024] figure 2 is an assembly diagram of an LCD module according to an embodiment of the present invention.

[0025] exist figure 2 In this case, the LCD panel 110 and the backlight unit 120 are assembled with parts of the mechanical structure to protect these parts and prevent light leakage from the assembled LCD module. Generally, the LCD panel 110 , the backlight unit 120 , and several mechanical parts may be collectively referred to as the LCD module 100 .

[0026] In addition, a backlight unit is located under the LCD panel 110 . The LCD module 100 also includes: a main frame 150 surrounding the edges of the LCD panel 110 and the backlight unit 120; and a bottom frame 160 for providing structural support and preventing light leakage from the backlight unit 120 when it is combined with the main frame 150 . In addition, the m...

Abstract

The present invention relates to a liquid crystal display device including transformer. The liquid crystal display device including a liquid crystal display panel, a printed circuit board connected to the liquid crystal display panel, a transformer connected to the printed circuit board, and a ferrite core plate disposed between the printed circuit board and the transformer.

Description

technical field [0001] The present invention relates to a liquid crystal display (LCD) device, and more particularly, to an LCD device having a transformer. Background technique [0002] Flat panel display (FPD) devices having characteristics of relatively light weight, thin profile, and low power consumption are being developed and widely used as replacements for cathode ray tube (CRT) devices. In general, display devices can be classified according to their self-emissive capabilities, which can include emissive display devices and non-emissive display devices. Emissive display devices display images by taking advantage of their self-luminous ability, while non-emissive display devices require light sources because they do not emit light themselves. For example, plasma display panel (PDP) devices, field emission display (FED) devices, and electroluminescence display (ELD) devices are generally used as emissive display devices. Liquid crystal display (LCD) devices, which c...
