A display device, comprising:
- a display panel;
- a plurality of lamps facing the display panel and arranged in parallel from a top portion to a bottom portion of the display panel;
- and
- a transformer connected to the plurality of lamps arranged,
- wherein the transformer is disposed between a predetermined portion of the display panel and the bottom portion, and wherein the predetermined portion is aligned in parallel to a length of the plurality of lamps and between the top portion and the bottom portion, and wherein the transformer includes a compensation transformer connected to a lamp of the plurality of lamps closest to the bottom portion of the diplay panel and a driving transformer connected to the plurality of lamps other than the lamp closest to the bottom portion of the display panel.
A display device, comprising:
- a display panel with a top portion and a bottom portion;
- a plurality of lamps facing the display panel and arranged in parallel;
- and
- a transformer connected to the plurality of lamps,
- wherein the transformer is arranged in a space inside the display device between a predetermined portion of the display panel and the bottom portion such that thermal distribution is substantially uniform in the space due to convection of the heat generated by the transformer, and wherein the predetermined portion is aligned in parallel to a length of the plurality of lamps and between the top portion and the bottom portion, and wherein the transformer includes a compensation transformer connected to the lamp of the plurality of lamps closest to a bottom portion of the display panel and a driving transformer connected to the plurality of lamps other than the lamp closest to the bottom portion of the display panel.
