Notebook LCD Display  Comparison


The screen size and resolution comparison tables compare common notebook TFT flat-panel displays from different brands. The characteristics of today's built-in LCD screens of portables are listed side by side.

The compared screens are presented two lists, the first focusing on the pixel related aspects and the second on the physical area aspects. All selected displays are for stationary or mobile use in laptops. Some of the shown values are calculated and can differ in reality (i.e. visible display diagonal).


Notebook LCD Monitor Comparison (Pixel Table)

This table shows the screen resolution, pixel density (pixel pitch in pixels per inch, ppi), size of one square pixel, aspect ratio of the screen, number of pixels (megapixels or MP), and pixel area gain compared to a 1024 by 768 pixel XGA resolution for various display sizes (measured by the viewable diagonal).

See the table below to compare the gain in physical size of the active or viewable screen area to the extra real estate in pixels (resolution gain in pixel). The aspect ratio also affects the gained area in cm2.

最近调整字体比较多,参考了很多资料,这篇帖子里提到查看笔记本LCD屏幕的DPI 值,网址被GFW盾了,我将网页内容保留了下来,为以后方便查阅,也为想要获取该信息的同学提供方便。
