Problems solved by technology

However, although the height of the transformer may be reduced, an additional inductor element providing inductance required for power conversion is formed on the circuit board, and since the inductor element also has a predetermined height, the thinness of the display device is limited.

Embodiment Construction

[0036] Exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0037] figure 1 is a schematic exploded perspective view of a planar transformer according to an exemplary embodiment of the present invention, and figure 2 is infigure 1 A schematic perspective view of a coupled planar transformer according to an exemplary embodiment of the present invention shown in .

[0038] refer to figure 1 and figure 2 , the planar transformer 100 according to the exemplary embodiment of the present invention may include a core unit 110 and a winding unit 120 .

[0039] The core unit 110 may include a first core 111 and a second core 112 . The pair of first cores 111 and second cores 112 may be EE or EI cores; however, the shapes of the coupled cores are the same. Therefore, the EE core will be mainly described. The first core 111 and the second core 112 may be electromagnetically coupled. To achieve this, the fir...

Abstract

Provided are a planar transformer, a driver and a display device provided therewith. The planar transformer with a leakage inductance increasing structure comprises a core unit. The core unit comprises a first core and a second core, the first core and the second core are electromagnetically coupled through at least one of a first column and a second column; and a winding unit, which comprises a first substrate and a second substrate. The first substrate and the second substrate have at least one surface of a predetermined area.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2010-0131699 filed in the Korean Intellectual Property Office on Dec. 21, 2010, the disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to a planar transformer having a structure in which leakage inductance is increased, and a driver and a display device having the planar transformer. Background technique [0004] In recent years, in the display industry, a new technology flat panel display (FPD) suitable for a multimedia system having a high resolution and a large screen has become prominent instead of a cathode ray tube (CRT). [0005] Specifically, in the case of large-sized displays, panel (liquid crystal display) TVs are becoming prominent, and are expected to attract more attention in terms of price and marketability in the future. [0006] In the case of existing panel TVs, although...
