Description

Folding smart phone with another electronic paper display

Technical Field

The utility model relates to a folding smart phone with another electronic paper display, in particular to a folding smart phone which can be used for watching characters, photos or videos without high color number, high pixel number and high refresh rate on the electronic paper display so as to reduce the harm to eyes.

Background

Human eyes always see the world with reflected light, that is, eyeballs judge the shape and color of an object by receiving the reflected light of light (sunlight or lamplight) irradiating the object, and the shape and color of the object are not changed until a television and a mobile phone are provided.

Electronic paper displays are reflective displays fabricated using electrophoretic (electrophoretic) or electrowetting (electrowetting) techniques. The electrophoretic display device reflects charged pigment particles to eyes by irradiating sunlight or lamplight, the charged pigment particles can be rearranged by applying an electric field, and the image change can be seen by the change of the electric field. The electrowetting display irradiates closed colored oil and water by sunlight or lamplight, the positions of the colored oil and the water can be moved by applying an electric field, and the image change can be seen by the change of the electric field.

The aforementioned LED/LCD and electronic paper display each have advantages and disadvantages, and the electronic paper display has the greatest advantage of reducing damage to eyes, and has the following advantages:

the displayed image can still be clearly visible under the direct illumination of sunlight, the visual angle is extremely wide, theoretically 180 degrees, the contrast is high, and in addition, when the image is not updated, the image can be continuously displayed without consuming electric power. The disadvantage is that the image re-arrangement speed or refresh rate of the electronic paper is too slow, the current color electronic paper is about 1fps (frame per second, i.e. 1 image per second), the black and white image is about 8fps, which is very different from the minimum 24fps required by the image playing, i.e. video, and is further less than about 50fps of the current 4G, i.e. 4 th generation mobile phone LED/LCD display, and about 90fps of the 5G mobile phone display. The mobile communication has a large communication volume after 4G, and is also a necessary function for the mobile phone after 4G, and at present, the mobile phone has 1600 ten thousand colors, the electronic paper has only 4096 colors, and the resolution, i.e. pixels (pixels), is also much worse, so that although the electronic paper is continuously advanced, the mobile communication cannot be independently applied to the smart phone unless the mobile communication is used in a very small number of special groups.

However, if a foldable reflective display is added to the smart phone, the two displays are integrated into a whole and have two screens with the original size of the smart phone, so that the foldable smart phone is formed. The user can see the two display screens simultaneously, the eyes can quickly browse the two screens, and the user can read the image without requiring high pixel, color number and refresh rate on the electronic paper display by selecting to watch any screen. Such as text or photos and video without fluency requirement, for users or children who pay attention to eye protection, the time for watching the two displays of the LED/LCD and the electronic paper of the mobile phone can be about half of that of watching the mobile phone, so that the harm of watching the mobile phone to eyes can be substantially reduced. In addition; the electronic paper display must be able to share various mechanical and electrical units of the smart phone, so that the cost of the foldable smart phone can be greatly reduced to be similar to that of a common smart phone, and the foldable smart phone can be widely popularized. And; a display processing/control module is needed to convert the pixel count, color count and refresh rate (fps) of the LED/LCD display into the pixel count, color count and refresh rate (fps) suitable for the electronic paper display, so that the two displays can simultaneously display similar pictures.

Additionally; although the electronic paper display is applied to the electronic book, the sale amount is limited due to the high price, because the parts of the electronic book are provided with mechanical and electrical units with about seven components of a common smart phone besides the electronic paper display, for example, the Nova 3color manufactured by arashi company sells RMB2750 in the tianmao website, if the electronic paper display can share the mechanical and electrical units of the mobile phone, the cost can be reduced to about two components of the electronic book, and the function is better. For example, the cost of the current electronic book is considered, only wifi is configured for downloading data, and 4G/5G communication function is not configured, so that the data cannot be downloaded outdoors, and in addition, as the indoor communication rate of 5G is more and more satisfied with the requirement of the actual use of consumers, many consumers stop renting wifi in the home after renting 5G, if the mobile phone shares wireless transmission, the transmission speed is reduced, the wireless transmission is also easily interfered, and the mobile phone needs to consume large electric power for transmitting wireless signals, the service life of the battery and the mobile phone can be reduced after long-term use, so that the wifi in the home can be continuously paid for renting for using the electronic book, and the promotion of the electronic book is hindered.

In view of this, a foldable smart phone with another electronic paper display may be designed, so that the electronic paper display can be widely applied to reduce the damage to eyes.
