One is the problem of insufficient brightness. The main advantage of LED display is the super adaptability to the complex and complex outdoor environment. The characteristics of the outdoor environment require that the LED display should be sufficient in sunny, cloudy, rainy and snowy weather, long distance and multiple viewing angles. Brightness is used to transmit information, so brightness is especially important. Due to insufficient LED brightness, LEDs can only act as supporting roles in the lighting industry, mainly for decoration. This is a huge challenge for the comprehensive application of tens of thousands of LEDs.
The second is the problem of LED color difference. There is basically no chromatic aberration problem in the application of a single LED, but if a large number of LEDs are used in combination, the chromatic aberration problem will be highlighted. Although there are techniques to improve this problem, due to the limitations of domestic technology and production level, there are still differences in the same batch of LEDs in the same color zone, and this difference is difficult to escape the eye-catching, so it is difficult to ensure the color of the LED display. Reducive and realistic.
The third is the LED display control chip. True color high-resolution LED electronic display as a new display medium, with its clear image and high-performance playback capabilities, has been increasingly valued by people. For the LED display unit, the three-primary LED dies are the core components, so high-quality dies with small wavelength differences and good luminous intensity should be used, and this technology is mainly in the hands of world-renowned companies, such as Japan's Nichia company, etc.
The fourth is heat dissipation. Because the outdoor environment temperature changes greatly, coupled with the display itself, it must generate a certain amount of heat. If the ambient temperature is too high and the heat is not good, it will probably cause the integrated circuit to work abnormally or even be burned, thus making the display system impossible. normal work.
The development of any industry will encounter the bottle of technical problems, especially high-tech industries such as LED display. Only when producers face up to the problem can they promote the development of the entire industry.
Drum type Rice Cooker
Features
This type rice cooker is famous with drum type appearance, which is easy operation and easy clean.
There are two type of inner pot , one type called white pot which is without non-stick but cheaper price .another one called non-stick pot is polished with emery, Also there are two type non-stick with different price ,it`s depending on different demands to use.
And the inner pot cannot be burned on the stove, which will make the pot transfigured and bad contact with the heating plate. While cooking , the heating plate or the fuse is most likely to be burned for the bad contact of the inner pot and the heating plate, Besides, make sure to dry the pot before putting into the outer shell of the rice cooker ,or else the drops of water flowing on the heating plate, will make the heating plate rusted.
Applications
Many peoples are used drum type rice cooker for congee and soup, some of peoples are prefer to use this type rice cooker for steaming.
