chip

What you said is a small capacitor placed next to the chip. 104 means that the capacity of the capacitor is 0.1uF. Its function is to decouple, filter and make the chip work normally.

Hello, yes. It's brighter in 4-scan than in 8-scan. If the driving circuit lights up all the pixels on the screen each time, it is called static driving. If the rows or columns lit up each time are discontinuous, for example, there are 1,2,3,4,5,6,7,8,9,10... Rows of pixels, one and nine rows are lit up at one time, then in a very short time, 1 and 9 are off, 2 and 10 are on, and then in a very short time, 3 and 11 are on, that is 1 / 8 scan; If 1 and 5 are on, it will be replaced by 2 and 6 lines in a short time. Recursion is 1 / 4 scan; Because people have the characteristics of visual persistence, they can't see that the light has been off, and they still look like a/

Generally, LED display, LED electronic display and full-color LED display will have different prices according to the difference of brand and raw materials. In the final analysis, the main reason for the price difference of LED electronic display screen must be analyzed from the purchase of raw materials of LED display screen. Generally, the raw materials of LED display screen can be divided into imported materials and domestic materials.

Generally speaking, the row and column control mode is used in the general control method of indoor screen, which is commonly known as the scanning mode. At present, the driving mode of LED electronic display has two kinds: static scanning and dynamic scanning. The static scanning is divided into static real pixel and static virtual, and the dynamic scanning is also divided into dynamic real image and dynamic virtual. For example, buroke LED electronic display is divided into indoor full-color LED electronic display scanning mode: P4 and P5 are constant current 1 / 16, P6 and p7.62 are constant current 1 / 8; The scanning mode of outdoor full-color LED electronic display: P10 and p12 are constant current 1 / 2 and 1 / 4, p16, P20 and P25 are static; Single and double color LED electronic display screen/

Look at your chip size, generally p16 is very easy to achieve more than 8000, static words.

Most of the posts about sharp belong to the latter category, claiming that they have purchased Sharp LCD TV products and found that the products have quality problems. For example, "I bought a 46 inch TV that was out of the stage. In the mall, the sharp salesman said: it's ultra-thin. He said he didn't use any high-definition dishes. He used ordinary dishes. As a result, when I bought it home, the picture was" dizzy ". After a while, I felt dizzy and asked the salesman. He said," this is normal ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~!!!!!

The display screen generally has monochrome display screen, two-color display screen and full-color display screen. According to the function, there are indoor display and outdoor display, as well as a kind of LCD splicing screen. If you buy a display on the Internet, you should go to the wugoukou led mall. They have good things, high cost performance and more security.

As a matter of fact, the technical threshold of LCD is not high. Anyone who wants to do it can do it, but the investment is too large, so many brands don't do it. In fact, the clarity of LCD mainly lies in the chip and backlight. In stores, you can see that the difference between Samsung and domestic computers does not lie in whose screen they use, but in what chip they use, because the chip decodes the signal rather than the screen, LCD screen as long as it is A-level screen is a good screen, no matter which manufacturer. Backlight technology is the future development direction of LCD. Domestic machine promoters say that they use Samsung screen, do demonstrations are high-definition digital player, why is not Samsung's image clear, the main problem lies in/
