According to NPD, the screens produced by the above three manufacturers have always used the so-called "a-Si TFT" technology, amorphous silicon thin film field effect transistors. However, the new iPad is equipped with Retina display, after testing the technical specifications is obviously higher than the a-Si TFT - which is equipped with 264 pixels per inch in the area of ​​9.7 inches, not a-Si TFT can be achieved.
As early as last year, it was reported that Sharp had been producing screens for the next generation of iPads. However, this news was questioned in January of this year. Some media pointed out that Sharp's IGZO screen simply failed to meet Apple's standards. It seems that the production of Retina displays is indeed a big challenge. Do you not know if the new iPad will be in short supply due to the production capacity of the screen?
Dual Color Controller are generally designed voltage 12V-36V, the number of each circuit LED 3-6 in series, current limiting resistor buck, each loop current of 20mA or less. A product of a plurality of LED circuit LED, the advantage of low pressure, simple structure, easy to design;
Dual Color Controller Drawback is: when the current large scale product, you need to configure the low-voltage switching power supply. Due to the limited shortcomings of products, low-voltage long-distance transmission is not possible, all led light bar controller [1] is limited to the small size of the product, such as text signs, small patterns and so on. According to this feature.
The controller design specifications of Dual Color Controller : 12V selection of 75A / 30V MOS power of control, the output current 8A / Road; 24-36V selection 60A / 50V MOS power of control, the output current of 5A / road. Users can control large ones selected according to the above specifications of Dual Color Controller, the transitions can choose to buy NE10 NE20 series of low pressure to low pressure controller series, the gradient. Note that LED must be common anode (+) pole connection method, controller Yin (-) pole, the controller does not include low voltage power supply.
Features Dual Color Controller to control more than large ones, to control the use of the serial signal transmission purposes, the general control unit 512 need only four control connection, serial LED controller LED light sources require board register with the controller can choose models NE040S controller, the controller has reached maximum capacity 4096KBit, if the load 512 LED unit 8192 can achieve maximum picture frame.
Mingxue Optoelectronics Co.,Ltd. has apply the I S O 9 0 0 1: 2 0 0 8 international quality management system certificate, for Dual Color Controller we apply the CE, RoHS and SAA certificate for our led lighting product.
