Course Introduction：This website reported on August 23 that according to a video from Samsung Display’s official YouTube account, the company demonstrated a new MicroLED screen prototype that can be stretched outward in the Z-axis direction at IMID2024, South Korea’s largest academic conference in the display field. Samsung Display states that the stretchable screen supports up to 25% elongation and can return to a flat surface when displaying three-dimensional graphics is not required. In addition, the screen prototype also has a pixel density of 120PPI, and both parameters of the same elongation rate rank first in stretchable displays. In the introductory video, Samsung Display used its stretchable MicroLED screen prototype to show the formation and general topography of the volcanic island of Jeju Island in South Korea. The stretchable nature of the prototype allows it to display clear images that are difficult to achieve with traditional 2D displays.

Course Introduction：Backstretch is a simple jQuery plug-in that can help you add a dynamic background image to a web page, which can automatically adjust the size to fit the size of the screen. Of course, the disadvantage of this is that when the image size is smaller than the screen, the image will automatically stretch. And deformation, so we can use high-resolution and large-size pictures as backgrounds, and more importantly, support automatic switching of pictures

Course Introduction：Image compression is a commonly used technical means when storing and transmitting images. It can reduce the storage space of images and speed up the transmission of images. The goal of image compression is to reduce the size of the image file as much as possible while trying to maintain the visual quality of the image so that it can be accepted by the human eye. However, during the image compression process, a certain degree of distortion often occurs. This article discusses the issue of distortion control in image compression and provides some concrete code examples. JPEG compression algorithm and its distortion issues JPEG is a common image compression standard that uses

Course Introduction：JPEG is used to compress still images. JPEG is a compression standard for continuous-tone still images, with the file extension ".jpg" or ".jpeg"; the JPEG standard is suitable for compressing still grayscale and color images. JPEG mainly uses a joint coding method of predictive coding (DPCM), discrete cosine transform (DCT) and entropy coding to remove redundant images and color data. It is a lossy compression format, which can compress images in a small storage space. Space will cause damage to image data to a certain extent.
