Extended information:

1. Origin of the Sharp brand

In 1915, Hayakawa Tokuji received an order for metal parts of automatic pencils. After improvements, Hayakawa Tokuji Invented the "Hayakawa-style automatic pencil", and in 1916 decided to use "Ever-Ready Sharp Pencil" as the brand of the new automatic pencil, taking its meaning of "no need to sharpen, the pen core can be kept sharp forever". The "SHARP" trademark later used by Sharp Company came from this.

2. Sharp’s core technology

1. Quattron is Sharp’s unique liquid crystal technology. It uses four-color filters to distinguish between red, blue and green. By adding yellow to the base color, a wider color gamut is achieved, allowing bright and vivid images to be reproduced more vividly.

2. Pure ion cluster technology

Through the special ion cluster release device, the air purifier will first release a large amount of H positive ions and O2- negative ions before working. These ions After condensation around the planktonic bacteria, a chemical reaction occurs and turns into OH hydroxide ion active oxygen. These OH hydroxide ions extract hydrogen from the proteins in the cell membrane of planktonic bacteria, thereby causing mold and viruses to lose their biological functions and achieve air purification effects.
