Resolution, pixel, and PPI, resolution, pixel PPI Screen SizeIt refers to the length of the diagonal line of the screen, generally in inches, 1 inch (inch) = 2.54 cm (cm ). In the traditional sense, the photo size is also the concept. Therefore, screens of the same size (diagonal) may have different aspect ratio.Pixel: This is an abstract concept in a bitmap (such as a digital image). It refers to the compu

The previous article analyzed the code of the first 10 basic experiments, starting from here to analyze the next 10 ~First, the PPI principle:PPI (Programmable peripheral interconnect), Chinese translation is a programmable peripheral interconnect.The PPI approach is set up inside nRF51822, allowing interconnection between different peripherals through tasks and events, without the need for CPU involvement.

Screen SizeRefers to the length of the diagonal of the screen, usually in inches, 1 inches (inch) = 2.54 cm (cm). The traditional picture size is also the concept. So the same size (diagonal) of the screen, may also be different length-width ratio. Pixel (Pixel): is a bitmap (such as a digital image) in the abstract concept, refers to the computer to the image sampling point, no specific size. Popular understanding is a single box (point) where the computer saves the location and color values of

On the Apple iphone 6s screen parameters I believe that everyone will not be unfamiliar, the size of 4.7 inches, 1334 x 750 resolution so that its PPI reached 326 SP and PX Conversion formula: sp*ppi/160 = pxConclusion:PX = dp*ppi/160DP = PX/(ppi/160)PX = sp*ppi/160SP = px/(

Pixels per inch is the image resolution unit, the higher the image PPI value, the more details of the picture will be richer, because the number of pixels per unit area is more, so the picture taken out by the digital camera because of brand or production time may be different, common have 72ppi,180ppi and 300PPI, This is the default. (27-inch Imac,ppi with 5K resolution up to 217) When your c

1. You can write and read the register values (byte, word, and dual-word ); 2. You can set and reset components (v, M, S, Q, And I; 3. the on/off status of the component (v, M, S, Q, And I) can be read. 4. PLC Operation and stop can be controlled. Published the popular PPI protocol on the Internet. Although this protocol is incorrect, the idea is correct. There are many ways to communicate between Siemens S7-200 PLC or between PLC and PC: Free Port,

, this time to display this point to mobile phone B (assuming that the phone B line has 100 pixels), if we press the physical pixels, Also assign it a pixel, it occupies 1% of the line, and on mobile phone a accounted for one-tenth, you will feel that on the mobile phone B has become very small, if the cell phone B line has 100,000 pixels, you can not see the element, because the invisible. So think of setting up a logical pixel, so from the new words: this element in mobile phone A to occupy a

Dpi, ppi, dip, dp, px, sp, dpippi Basic Concepts 1. dpi (dots per inch): The number of dots per inch; ppi (Pixel per inch): The number of dots per inch. Designed for the monitor, dpi = ppi. 2. dip (device independent pixels) devices are independent pixels. Different devices have different display effects, which are related to device hardware and do not depend

Brief Introduction Recently only really understand what is px, the spirit of the problem fully figured out the attitude, and thus explore the corresponding information. The feeling and the hair, record. what is px. PX, full name pixel, translation is the meaning of "pixel", representing the screen resolution unit, EX:1366*768PX.however PX does not represent a length unit , PX is more like a color block, such as a 1366*768px screen notebook, which shows that the screen has a maximum of 1366 pix

We know that the screen size (in inches) of mobile phones on the market is getting bigger and bigger, Yes, it is really cool to hold a big screen mobile phone in your hand. But if the screen size increases, will the user experience be satisfactory? Of course not. User experience is also related to resolution. Currently, the most common indicators for cell phone screen clarity are: PPI and DPI. PPI
