After research, the current IC cannot achieve this effect. If you want to do it, you must meet the conditions for issuance. 1. The power supply must be 4.5V (currently 3V), because the minimum requirement for the blue LCD light is 2.9V-3.2V. If a 3V power supply is used, the battery will fail quickly. The battery may need to be replaced after 1-2 hours. 2. The IC needs to be developed from scratch, because the current IC does not have a light switch pin. The light is on when the IC is working and goes off when it is not working. It is estimated that there will be four sets of molds. How much will they cost? (The cost of the molds can only be determined after they are completed.) How much does the figure cost? When making a figure, you need to open the LCD glass piece (I don’t know the molding fee) The cost of electronics has not yet been determined.
Blue LED lights require 2 pcs, which is estimated to cost $0.02/2 pcs. There are also reflective panels (the requirements are also high, the electrical appliances have been made, and they are processed from outside. If you make them yourself, it may cost $0.15/pc). The above are estimates.
