Problems solved by technology
[0003] At present, it is relatively simple to output information by modulating the output brightness of the display screen. Generally, binary information is used for output. The traditional single-line coding method is also binary coding. There are only two output effects of bright and dark. need
The multi-ary data output is very fast, but due to the uneven output brightness of the display screen and the brightness curve characteristics of the display screen, too many levels of brightness are not easy to be correctly recognized by the reading device; at the same time, the output of the display screen If the rate of change is too fast, it will also be limited by the performance of the display itself

Embodiment Construction
[0047] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0048] refer to figure 1 , figure 1 It is a schematic flow chart of the first embodiment of the encoding method for outputting information through the display screen of the present invention; as figure 1 As shown, the coding method for outputting information through the display screen of the present invention comprises the following steps:
[0049] Step S01, convert the information to be sent into N-ary data, and judge whether there is continuous identical data in the N-ary data; if so, execute step S02;
[0050] Usually, most of the output information of the display screen of the terminal equipment is decimal data that is easy to recognize by humans or binary data...

The invention discloses an encoding method for outputting information through a display screen. The encoding method comprises the following steps of: converting information to be transmitted into N-ary data; judging whether continuous and identical data is present in the N-ary data, if so, converting the (even number)th identical data into data different from the N-ary data, so as to obtain (N+1)-ary data; adding a first data comprising the N-ary data or the (N+1)-ary data into a synchronization header, so as to obtain a second data carrying the synchronization header; and modulating a pixel value of the specific display screen area according to the second data, so as to obtain brightness information carrying the second data, displaying and outputting the brightness information through the display screen, and reading the information through external equipment. The invention also discloses an encoding device for outputting information through the display screen, and a terminal. The information to be transmitted is converted into the N-ary data or the (N+1)-ary data, so that the brightness information is obtained and is displayed and output, and the method has the beneficial effects that the information output speed and brightness are easily identified and unified.
Description
technical field [0001] The present invention relates to the technical field of information output, in particular to an encoding method, device and terminal for outputting information through a display screen. Background technique [0002] With the continuous advancement of global digital information, the upgrading of electronic products in the electronics industry is also getting faster and faster; and many electronic products, such as PCs (Person Computers, personal computers), tablet computers, smart phones and other terminal devices, exist There are a series of problems such as inconsistency and backward compatibility of the communication interface, and even the communication interface needs to be authorized to use. In the prior art, there is no method or device that is universal and compatible with communication interfaces of various terminal equipments to realize the communication between the above-mentioned different types of terminal equipments. In order to provide a...
