What Is the Difference Between Photoelectric Mouse and Laser Mouse

(source: Great Xia U)The mouse can be said to be one of the important peripherals of the computer, and whether the mouse is good or not depends on the sensor inside the mouse. At present, if it is distinguished by the sensor on the market, it can be mainly divided into the photoelectric mouse with built-in optical sensor and the laser mouse with built-in laser sensor. So what's the difference between the two kinds of mice? Next, Xiaobian will take you to have a good understanding of photoelectric mouse and laser mouse.

What is a photoelectric mouse? The photoelectric mouse uses optical sensors, and most of the current mice basically use optical sensors. The working principle of the photoelectric mouse is to shoot LED light at a 30 degree angle to the desktop, illuminate the shadow generated by the surface, and then feed back to the sensor through another lens through the refraction of the plane. This is very similar to the camera, except that instead of taking pictures, it captures images on the desktop. Finally, the images are converted into data to track the periphery of the desktop to determine the moving position of the mouse.

What is a laser mouse? Laser mouse can be said to be an upgraded version of photoelectric mouse, which upgrades LED light into laser, with higher accuracy, higher DPI and adaptability to different types of performance. For example, the laser mouse can be used on glass, but the photoelectric mouse can't.Differences between photoelectric mouse and laser mouse: 1. Photoelectric mouse adopts LED light, while laser mouse adopts invisible beam. 2. In terms of adaptability of different types of performance, laser mouse can be used on glass and mattress, while photoelectric mouse can't.3. In terms of accuracy, the laser mouse is higher than the photoelectric mouse, but too high accuracy also has disadvantages. It may collect some useless information. Moreover, when the laser mouse moves at a slow speed, it will cause the cursor on the screen to shake. In this way, there is no way to locate quickly, but it is said that this problem has been improved.

4. The laser mouse has high DPI, which is to protect the stability of the mouse and higher dpi resolution.
