Abstract

The invention provides a sunlight collecting device comprising a lens substrate, a plurality of Fresnel lenses, a connector substrate, a plurality of optical fiber connectors and a spot following substrate. The lens substrate is provided with a plurality of round hollow holes. The Fresnel lenses are arranged on the lens substrate correspondingly to the round hollow holes. The connector substrate is parallel to the lens substrate. The connector substrate and the lens substrate are focused at an interval. The optical fiber connectors can be adjustably arranged on the connector substrate. The spot following substrate arranged between the lens substrate and the connector substrate is used for rotating the lens substrate and the connector substrate simultaneously to enable the Fresnel lenses to directly face sunlight. The invention further provides a liquid crystal display utilizing the sunlight as a backlight source.

Description

【Technical field】 [0001] The invention relates to a sunlight utilization technology, in particular to a sunlight collecting device and a liquid crystal display using sunlight as a backlight source. 【Background technique】 [0002] At present, since liquid crystal displays cannot emit light independently, they all need to use a backlight as a light source. Existing common backlights are light-emitting diodes or cold-cathode lamps, which use electricity to drive the backlight of the backlight module. However, the power consumption of the backlight in the entire display accounts for about 80% of the entire system. . Under long-term use, its energy consumption is very considerable. Among the currently used types of power generation, the main sources of power generation are oil combustion power generation and nuclear power generation, and they will bring environmental pollution and the greenhouse effect that causes drastic changes in climate and other related environmental issue...
