Embodiment 1

[0022] A preparation method of a capacitor for an LCD display, the specific preparation steps are:

[0023] (1) Weigh the silicon powder and put it into a jet mill to pulverize for 20 minutes to obtain a silicon powder pulverization, mix the silicon powder pulverization with silicon carbide and put it into a high-temperature processor at a temperature of 300 degrees Celsius;

[0024] (2) After the above-mentioned treatment is completed, filter and separate to obtain the filter residue, put the obtained filter residue into a carbonization furnace at 600 degrees Celsius, feed nitrogen into the furnace until all the air is replaced, heat up and keep warm for carbonization, and obtain a carbonized preform;

[0025] (3) Transfer the carbonized preform obtained above into a beaker, add a potassium oxide solution with a concentration of 1 mol / L and a temperature of 35-50 degrees Celsius until the carbonized preform is completely submerged, place it on a shaker to vibrate and activate ...

Abstract

The invention relates to a preparation method of a capacitor for an LCD and belongs to the technical field of electronic component preparation. The method comprises specific preparation steps that silicon powder is weighed and put into a jet mill to crush for 20-30 min, silicon powder crushed matter is obtained, and the silicon powder crushed matter and silicon carbide are mixed and then put intoa high-temperature treatment machine with the temperature ranging from 300-500 DEG C; after treatment is finished, filtering and separating are performed to obtain filter residues, the obtained filterresidues are put into a carbonization furnace at 600-800 DEG C, nitrogen is introduced into a furnace till all the air is replaced, and heating, preserving heat, and carbonizing are performed to obtain a carbonized preform.

Description

technical field [0001] The invention relates to a method for preparing a capacitor for an LCD display, belonging to the technical field of electronic component preparation. Background technique [0002] LCD (Liquid Crystal Display) may not be a new term for many users, but the history of this technology may far exceed our imagination. As early as the end of the 19th century, Austrian botanists discovered liquid crystals, that is, liquid crystals, which means that a substance has both the fluidity of liquid and certain arrangement characteristics similar to crystals. Under the action of an electric field, the arrangement of liquid crystal molecules will change, thereby affecting its optical properties. This phenomenon is called the electro-optic effect. Utilizing the electro-optic effect of liquid crystals, British scientists manufactured the first liquid crystal display, or LCD, in the last century. [0003] A large number of capacitors are needed in the LCD display screen...
