Xteink X4pro E-book Reader, E-ink Screen

This description is Yuexingtongs R & D positioning based in the custom ultraportable electronic paper segment. Our definition of ultra-portable electronic paper specifically refers to: electronic paper device with a weight of 580 g, one thickness 6 mm and a screen size of 34.5 inches, focusing in portable fragmentary reading scenarios. This statement is just for this custom segmented track. It is not an absolute statement by industry and it does not represent the state of the electronic paper industry as a whole. It is the conventional reference nominal value of the product. Due to the differences in batch materials, processes production and assembly and manual weighing, there are small tolerances and reasonable. The value is only used as a parameter reference and the actual weight of the real object. This is the nominal factory capacity. Due to differences in the layout of cells, standards industry capacity calibration and discharge losses, there are reasonable errors. The values are only as parameter reference and are subject to the actual operating conditions of the battery. The time of use is calculated from energy consumption design theory and is not measured in actual use. Since the actual frequency of use, environment and system of each person are different, the values are only used as reference of parameters and are subject to real use (energy consumption) per hour is 50 to 80 mAh, the nominal capacity of The battery is 1100 mAh, used 1 hour per day, in theory can be used for 10 days). The size of the on-screen logo is the conventional rounded approach of industry. The actual physical size is 4.26 inches. The product screen has a rounded corner design. When measured according to a standard rectangle, the diagonal length of the screen is 4.26 inches (the actual viewing area is slightly smaller).
