Abstract: According to the disclosure, a display apparatus includes a printed circuit board (PCB), a light emitting diode (LED) chip mounted on the PCB and configured to emit light, an optical dome formed to enclose the LED chip by being dispensed on the LED chip, and a liquid crystal panel configured to block or pass light output from the LED chip, wherein the optical dome may be formed to satisfy 1.70<r1/r0<1.83 where r0 is a straight distance for light vertically emitted from the LED chip to reach a surface of the optical dome and r1 is a straight distance for maximum output light emitted from the LED chip to reach the surface of the optical dome.

Abstract: A display apparatus is provided. The display apparatus includes: a backlight unit including a substrate and light sources configured to emit light to a liquid crystal panel; and a processor configured to: identify a plurality of dimming blocks, each of which includes at least one light source among the plurality of light sources; predict a temperature for each of the plurality of dimming blocks based on a dimming signal corresponding to an input image and current-specific temperature profile information corresponding to the plurality of dimming blocks; update the dimming signal based on the temperature predicted for each of the plurality of dimming blocks; and control a supply current for each of the plurality of dimming blocks based on the dimming signal.

Abstract: A display panel includes: a substrate; a plurality of substrate electrodes on the substrate; a plurality of first light emitting diodes electrically connected to the plurality of substrate electrodes, and configured to emit light of a first color; and a plurality of second light emitting diodes electrically connected to the plurality of substrate electrodes, each of the plurality of second light emitting diodes being configured to emit light of a second color and emit light of a third color, wherein the second color and the third color are different from the first color.

Abstract: A display device includes: a display panel; a light source module on a rear side of the display panel and configured to generate light supplied to the display panel, the light source module including a plurality of light sources configured to emit light and a printed circuit board (PCB) on which the plurality of light sources are provided; and a bottom chassis on a rear side of the light source module and on which the light source module is provided, wherein the PCB includes: an insulating layer, a first conductive layer on a lower surface of the insulating layer, and a second conductive layer on an upper surface of the insulating layer, and an area of the second conductive layer is smaller than an area of the first conductive layer, and the PCB is convexly bent in a direction toward the display panel.

Abstract: The present disclosure relates to a method for treating a solvent in wastewater generated in a polycarbonate production process. More specifically, the present disclosure relates to a method for treating a solvent in wastewater generated in a polycarbonate production process, which can easily recover a high purity solvent regardless of the concentration of the solvent by using a membrane distillation method to reuse it, and contribute to energy savings.
