Led matrix and pixelation
The LED matrix was a layout consisting of multiple LED light sources. These LED lights could be controlled independently to achieve different lighting effects or display functions. Taking the car field as an example, the matrix LED headlights of the Buick Regal GS consisted of 105 LED light sources, forming 84 independently controllable lighting zones. This was an application of the LED matrix in lighting. Pieces were used to describe the resolution of the LED beads in the matrix. Like Porsche's newly announced "HD matrix LED flashlight" headlights technology, each light group was composed of 16384 LED lamp beads, and the two headlights had a total of 65536-pixel-matrix light source. Compared to the existing headlights that provided 84-pixel-matrix light sources, the light source projection accuracy of the new product was improved by several orders of magnitude. In the field of LED screens, such as transparent LED screens, there was also an LED matrix. The screen was assembled from a series of individual LED dots in a matrix pattern, and each dot emitted light to present the overall color. This meant that whether it was in lighting or display devices, the LED matrix and the concept of the pixelated were related. The pixelated was an indicator of the degree of detail of the LED beads in the matrix, and the matrix was the layout of many LED beads. Read more exciting novels for free

Scripting, creating pixelation
One way to create a pixelated map with a script was to first take out the rmb value of each pixelated point in a pixelated map, then use the script to operate excel and set the rmb value as the background color of the cell. This process mainly involved two points: one was to use Python to do image processing, which would use the Image module; the second was to use Python to operate excel. There were three main methods to operate excel with Python on the Internet, namely xlrd, xlwd, xlutils, pyExcelerator, and pywin32. The first two had better support for simple excel operations and were cross-platform, while Pywin32 was equivalent to excel's interface. It had rich operations, but it could only be done under the window and excel was installed. In this application, because the background color needed to be set according to different rmb values (the first two can only set common color values), so Pywin32 was selected. It should be noted that when setting the color, the rmb must be converted to hex, and the order of the rmb values must be reversed first. Otherwise, the color value set is opposite to the rmb value passed in. Through these two libraries, one could automatically draw a picture in excel. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What is the printing pixelation setting?
Different types of printed matter had different requirements for the pixelation settings: 1. ** Four-color printing manuscript **: The basic resolution requirement is 300dpi or above. Some high-end fashion magazines require a resolution of more than 1000. 2. ** Black-and-white manuscript **: The resolution requirement is relatively low, but it should be around 200dpi. 3. ** Ink jet printing electronic file **: The resolution varies with the size. Generally, the media used by the ink-jet printer is 30 - 45dpi. For large anti-aircraft gun advertisements, the resolution can be appropriately reduced, or even less than 10dpi. The photo output image is small, and the resolution is generally not lower than 72dpi. The recommended resolution is 120dpi. 4. ** Digital printing (commonly used for small batches of picture albums, posters, flyers, etc.)**: The recommended resolution is 300dpi, and the minimum is 200dpi. 5. ** newspaper printing **: The scanning resolution is 125 - 170dpi. For printed images, the resolution is set to 1.5 to 2 times the screen line (85lpi for newspaper printing). 6. ** Magazine/promotional material printing **: Scanning resolution of 300dpi (133 or 150dpi for magazine printing). 7. ** High-quality book printing **: The scanning resolution is 350 - 400dpi (175 - 200lpi for book printing). 8. ** Wide-format printing (such as posters and other large-format images that can be seen from afar)**: The scanning resolution used is 75 - 150dpi. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Comparing the pixelation of the iPhone with the iPhone
There were many different types of cell phones with different pixelation. For example, the 808 had 41 million pixelation, the Lumia 1020 had 41 million pixelation, and the N9 had 8 million pixelation. There was also a cell phone with 13 million pixelation and two 2 million pixelation camera modules. The iPhone 4S, the iPhone 6, and the iPhone 6 Plus all used 8 MP cameras, while the iPhone 6S and the iPhone 12 series used 12 MP cameras. It can be seen that there are models with higher resolution than Apple phones, such as the nokia808 and nokia1020, and there are also models with lower resolution than Apple phones, such as the nokiaN9. The resolution of the two models varies. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What's with the pixelation on the screen?
If there were any dots on the screen, it could be one of the following: 1. ** Screen design and manufacturing factors ** - During the design and manufacturing process of the screen, the dots were evenly distributed across the entire display area. However, due to the limitations of the manufacturing process, there might be small differences in the display of the screen. For example, in a liquid crystal display (LCD), the arrangement of the dots and the attachment of the liquid crystal layer may not be perfect at the edges, causing the dots to look a little strange. In an OLED screen, each of the dots emitted light independently. The edge of the dots might be different from the center of the screen when displaying certain colors or brightness due to the circuit layout or packaging process. 2. ** Screen damaged ** - Physical damage: If the screen is hit, squeezed, or other physical external forces, the edges of the screen may be damaged. For example, if the phone screen fell to the ground and the edge touched the ground, it might cause the edge of the screen to malfunction. The performance was that the edge of the screen did not emit light, the color was abnormal, or there was a bad point (it always showed a certain color and did not change with the image). - "chemical damage: Contact with certain chemicals, such as strong acid and base solutions, may corrode the materials at the edge of the screen and affect the normal display of the dots. For example, if a liquid containing acidic substances was accidentally sprinkled on the edge of the screen, it might damage the structure of the dots or the related circuits, causing a display problem. 3. ** Problem with software and display settings ** - <<display resolution setting>: If the display resolution is not set properly, it may cause the display of the edge of the screen to be abnormal.>For example, when the set resolution did not match the actual physical layout of the screen, the edges of the screen might be stretched, compressed, or misaligned. - For a computer screen, if the display driver is faulty or the version is too old, it may not be able to control the display of the edges of the screen. The driver was responsible for converting the computer's image signal into a signal that the screen could recognize. If there was a problem, it might cause the display of the pixelated points to be chaotic. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
