    • There is provided a liquid crystal display. The liquid crystal display includes a TFT-LCD panel having any one of a variety of shapes including a circular shape, an elliptical shape, a circular arc shape, and a shape with an angle other than 90°; a plurality of straight light sources disposed at a rear side of the TFT-LCD panel and having a different length according to the shape of the TFT-LCD panel; and an inverter and a transformer connected to one terminal of each light source, wherein the inverter induces a same current to the light sources having a different length and the transformer supplies a boosted voltage lo dependent on the length of each light source to the light source so that luminance is uniform. With the straight light sources having a different length for a back light unit suitable for a liquid crystal display panel having a variety of shapes including circular, elliptical, fan, and semicircular shapes according to the present invention, image quality of uniform luminance can be implemented on the entire display area of the panel.
    • 提供了液晶显示器。 液晶显示器包括具有圆形,椭圆形,圆弧形和角度不为90°的形状的各种形状中的任何一种的TFT-LCD面板; 多个直的光源,设置在TFT-LCD面板的后侧,并具有与TFT-LCD面板的形状不同的长度; 以及连接到每个光源的一个端子的反相器和变压器,其中所述反相器对具有不同长度的光源引起相同的电流,并且所述变压器将取决于每个光源的长度的升压电压提供给所述光源 使亮度均匀。 对于适用于具有根据本发明的圆形,椭圆形,扇形和半圆形的各种形状的液晶显示面板的背光单元的直线光源,可以实现均匀亮度的图像质量 在面板的整个显示区域。
