Problems solved by technology

[0008] In addition, as display devices become larger, the length of the lamp becomes longer, so the initial discharge voltage required by the lamp becomes much higher
Therefore, when an electronic component such as a ceramic capacitor that stabilizes a driving voltage of a high voltage is omitted, the stability of the inverter deteriorates

Embodiment Construction

[0042] In the following, the invention will be described more fully with reference to the accompanying drawings, in which embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the example embodiments set forth herein. Rather, these example embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity.

[0043] It will be understood that when an element or layer is referred to as being "on," "connected to," or "coupled to" another element or layer, it can be in the On, connected to, or bonded to another element or layer where an intervening element or layer is present. In contrast, when an element is referred to as being "directly on," "directly connected to" or "directly coupled to" another el...

Abstract

In a voltage supply module and a backlight assembly having the same, a converter is disposed on a first face of a board and converts basic voltage into driving voltage. A capacitor includes at least one first electrode connected to an output line of the converter and at least one second electrode disposed to be spaced apart from the first electrode along a direction substantially parallel with the first face. A plurality of the second electrodes are disposed on the board between the first electrodes. The first and second electrodes form a ballast capacitance.

Description

technical field [0001] The invention relates to a voltage supply module and a backlight assembly with the voltage supply module. More particularly, the present invention relates to a voltage supply module for supplying voltage to a light source of a display device and a backlight assembly having the voltage supply module. Background technique [0002] Flat panel display devices have various advantages such as slim size, light weight, and low voltage consumption. Thin film transistor liquid crystal display (TFT-LCD) devices are capable of displaying high-quality images, and TFT-LCD devices have been developed to provide image display quality substantially comparable to cathode ray tube (CRT) devices. LCD devices have been widely used, and plasma display panel (PDP) devices have also been used in various fields. [0003] The display panel of the LCD device displays images using light supplied from the outside. The LCD device includes a backlight assembly that provides light...
