    Abstract: A backlight unit which provides light to a liquid crystal display panel of a liquid crystal display. The backlight unit includes an optical lens module including an optical lens disposed above a point light source and configured to refract light output from the point light source, and a reflective polarization layer disposed directly on the optical lens and configured to separate polarization components of the light to transmit one polarization component and reflect another polarization component.

    Abstract translation: 一种向液晶显示器的液晶显示面板提供光的背光单元。 背光单元包括光学透镜模块，该光学透镜模块包括设置在点光源上方的光学透镜，用于折射从点光源输出的光;以及反射偏振层，其直接设置在光学透镜上，并且被配置为分离光的偏振分量 以透射一个偏振分量并反射另一个偏振分量。

    Abstract: A display device includes a display panel; a pressure sensor disposed on the display panel; and a lower bracket. The pressure sensor is disposed between the display panel and the lower bracket and is disposed on the lower bracket. The pressure sensor includes a first substrate, a first pressure sensing layer disposed between the first substrate and the lower bracket, a first driving electrode disposed between the first pressure sensing layer and the lower bracket, and a first sensing electrode spaced apart from the first driving electrode. A gap is present between the first pressure sensing layer, and the first driving electrode and the first sensing electrode.
