Abstract: An approach is provided for a light source module and a display device including the same. The light source module includes two first light source packages configured to emit light of a first color, one or more second light source packages disposed between the two first light source packages, and a plurality of third light source packages disposed between the two first light source packages and alternately arranged with the one or more second light source packages. The one or more second light source packages are configured to emit light of the first color and the plurality of third light source packages are configured to emit light of a second color. An intensity of light emitted from each of the one or more second light source packages is approximately twice an intensity of light emitted from each of the two first light source packages.

Abstract: A sensor for measuring heat generated from cells, including a thermopile manufactured by surface-micromachining technology, and a microfluidic flow-channel structure for mixing cells with medium and dividing the mixture into cells and medium. Medium and cells are uniformly mixed using a micro-mixer. The mixture is separated into a medium microfluid and a cell microfluid using the Zweifach-Fung effect, after which signals measured in the two microfluids are amplified. The difference between the two signal values determines the amount of heat generated from the cells. The influence of noise caused by a change in external environment is eliminated. Convection heat dissipation caused by fluid flow is minimized. The sensor accurately measures the amount of heat generated from cells flowing in the microfluidic flow-channel. Diseases such as cancer are diagnosed using the difference between the measured amount of heat generated from cells and the standard amount of heat generated from normal cells.
