Description
Technical Field
The invention relates to the field of electronic reading products, in particular to an electronic book reader with an HDMI data transmission function.
Background
Currently, most of electronic book readers adopt an EInk technology. The EInk technique, also known as an electronic ink technique, is a display technique based on an electrophoresis technique. Electronic ink consists of millions of tiny microcapsules, approximately as large as human hair in diameter. Each microcapsule contains positively charged white particles and negatively charged black particles suspended in a transparent liquid. The charged particles of black and white two colors float up and down in the liquid capsule under the action of the electric field to form a picture. After the picture is formed, the color particles stop moving, and the picture does not disappear even if the power is off. Therefore, when a page is turned, the screen does not blink.
The EInk technology is of a total reflection type, is similar to the effect of paper, and has the advantages of small burden on eyes, no injury to eyes, low power consumption, power saving and the like compared with a liquid crystal display screen, and the EInk technology is adopted by a plurality of manufacturers of electronic book readers.
However, products of all current brands of large electronic book readers only support the function of reading electronic books, do not support the function of data transmission of the HDMI interface, and cannot be used as Eink computer displays, and conventional computer liquid crystal display screens supporting the function of data transmission of the HDMI interface are very easy to cause eye fatigue and eye diseases such as xerophthalmia.
On the basis, the application creates a new e-book reader with the HDMI data transmission function based on the Eink technology, so that the e-book reader has the e-book reading function and the function of transmitting data through the HDMI as a computer display, and becomes an object which is in great need of improvement in the current industry.
Disclosure of Invention
The technical problem to be solved by the invention is to provide an e-book reader with an HDMI data transmission function, so that the e-book reader has an e-book reading function and an HMDI data transmission function and has a computer display function, thereby overcoming the defects of the existing e-book reader.
In order to solve the above technical problems, the present invention provides an electronic book reader with HDMI data transmission function, the electronic book reader includes a display screen and a signal converter connected to a processor,
the display screen is a display based on Eink technology;
the signal converter is connected with a computer host to obtain signals from the computer host and convert the signals into signals suitable for the display of the display screen.
As an improvement of the invention, the signal converter comprises an extractor, a buffer and a converter connected in sequence,
the extractor is connected with the computer host and is used for extracting signals from the computer host and transmitting the signals to the buffer; the buffer is used for buffering the received signals; the converter is connected with a processor of the electronic book reader and used for converting the signals stored in the buffer into signals which can be displayed by the display screen.
In further improvement, the signal converter is connected with the computer host through an HDMI data line.
In a further improvement, the signal converter is arranged on a mainboard of the electronic book reader, and an HDMI interface is arranged on the mainboard of the electronic book reader.
In a further improvement, the electronic book reader further comprises a built-in SD card, a memory DAM, a battery and a power management unit.
In a further improvement, the electronic book reader further comprises a foldable support.
After adopting such design, the invention has at least the following advantages:
the invention adds signal converter and HDMI data interface to the Eink technology based electronic book reader, which has computer display function, creatively adds new function to the basic function of the electronic book reader, becomes a product integrating the electronic book reader and the computer display, not only can display the content of the electronic book as the electronic book reader, but also can convert the signal received from the computer through the HMDI data interface into the picture signal displayed on the Eink display screen, and can be used as the external computer Eink display.
The invention greatly solves the problem that people suffering from asthenopia and xerophthalmia feel pain when staring at the liquid crystal display screen of the computer frequently, effectively reduces the damage of blue light of the liquid crystal display screen to eyes, and further can reduce the discomfort of eyes caused by staring at the computer for a long time.
