In terms of profitability, it is reported that since the price of sapphire substrates has continued to decline recently, after the price in the fourth quarter of 2010 has risen to 30-35 US dollars/piece, with the new capacity of suppliers gradually opened, the first quarter of 2011 will be the sapphire substrate. The quotation has dropped slightly to $30/piece, and since March this year, more manufacturers have lowered their prices to around $25. Due to the decline in raw material costs, it is expected that there will be positive help in the profitability of the second quarter.
As for the price of LED chips, Yuyuan believes that because of the demand for LED lighting in Japan, it will definitely rise sharply after the disaster. Under the support of demand, it is expected that the LED grain price will fall in the second quarter of this year, and this year's LED is not big. There should be no oversupply in the grain.
The RGBW Color Controller is in a predetermined order to change the main circuit or control circuit wiring and circuit changes the resistance value to control the motor start, speed, braking and reverse master device to control RGBW color.
The same design with RGB Color Controller . The difference in coding for RGB and Rgbw Color Controller.
The RGBW Color Controller subassembly logic controllers and micro-program controller two controllers each have strengths and weaknesses. Combinational logic controller designCumbersome, complex structure, once the design is complete, you can not modify or expand, but it's fast. Micro-controller design program easy, simple structure, convenient to modify or expand, modify a machine instruction function, simply restated the corresponding micro-program;
To add a machine instruction, just add some micro-control program in memory, however, RGBW Color Controller is through the implementation of a micro program.
Specific comparison is as follows: a combination of hardwired logic controller, also known as the controller, by the logic circuit, relies entirely on hardware to achieve the function of the instruction.
RGBW Color Controller Basic components
(1) the instruction register is used to store instruction being executed.
(2) Operation code decoder: instruction opcodes for decoding to produce the corresponding control level, to complete the analysis function of the instruction.
(3) Sequential Circuits: used to generate a time stamp signal.
