Optionally, one can add either zinc alkyl ester scavenger, organotin stabilizer, or both to further improve the effectiveness of the essentially pure calcium carbonate.

The present invention relates to a mobile phone device, more specifically, to a sunlight illuminated and sunlight readable mobile phone device. The display panel opens a transparent window to the ambient light, which allows the sunlight to illuminate the display in both indoor and outdoor applications. A light collecting panel is introduced to reflect or transform the external light with a suitable angle relative to the display panel. A mobile phone with sufficient high contrast ratio, superior readability and ultra wide color gamut has been achieved. The solar light can be utilized as the lighting source in both indoor and outdoor display modes, thus remarkably reduces the power consumption and substantially prolongs the operation time of the rechargeable battery.

The invention discloses an active solar energy greenhouse heat collecting and storing system which combines a north wall of an agricultural greenhouse with solar energy heat collecting and phase change heat storing. A solar energy heat absorbing plate and a heat storing unit provided with phase change heat storing material are integrated on the north wall of the agricultural greenhouse. In the daytime, the sunlight irradiates on the heat absorbing plate, the solar radiant energy is converted into the heat energy, and the heat is transferred to the heat storing unit after the heat absorbing plate is heated. The phase change material in the heat storing unit is molten after being heated and the heat is stored. At night, the heat storing unit slowly radiates heat to the greenhouse through radiation; when the temperature is too low, a fan is started to drive the air to flow so as to lead the heat to be radiated quickly from the heat storing unit for heating the greenhouse at night, thereby achieving the purpose of heat storing in the daytime and heating at night for the agricultural greenhouse. The invention has the advantages of simple structure, small occupied area and high thermal efficiency and can effectively improve the night temperature of the agricultural greenhouse and further improves the crop yield by full use of the solar energy and the heat insulating performance of the greenhouse under the premise of consuming few conventional energy resources (electric energy of the fan).
