Detailed Description
For a clear description of the present invention, the following description will be further described with reference to the accompanying drawings and examples, but it is understood that the scope of the present invention is not limited thereto, and that simple substitutions of changes that can be made by those skilled in the art without creative efforts will fall within the scope of the present application, and for better explaining the working mode of the present application and avoiding tedious and lengthy substitution, the light emitting point capable of working normally will be referred to as "good point" hereinafter; the light emitting point which cannot normally operate is called a "dead point".
Referring to fig. 1, the present invention discloses a partition display method for a display screen, comprising the following steps:
s1, establishing a coordinate system, and carrying out coordinate correspondence on each light-emitting point on the whole display screen to obtain a unique coordinate of the light-emitting point;
s2, detecting whether the luminous point can work normally or not, and transmitting detection information to a control unit;
s3: the control unit screens the luminous points according to the detection information, coordinates of the luminous points meeting the requirements are sorted, and a display area is constructed;
s4: and transmitting information to the display area, and displaying a picture in the display area.
In this embodiment, a coordinate system is first established, so that all the light-emitting points can effectively exist in the coordinate system, and a unique coordinate value is obtained, where the light-emitting point is a minimum unit capable of displaying on a display screen, and in an actual process, the light-emitting point may be a single LED light-emitting lamp or a light-emitting module composed of a plurality of LED light-emitting lamps, and each light-emitting point is independently controlled, and any two light-emitting points are not affected with each other, so that after the control unit transmits information to all the light-emitting points, each light-emitting point can independently execute corresponding instruction information, thereby realizing display of a picture; after the coordinate information of each light-emitting point is obtained, the detection unit is used for detecting the light-emitting points, whether the light-emitting points can normally operate is judged, and related information is transmitted into the control unit, so that the control unit can ensure that subsequent information cannot be transmitted to a damaged light-emitting point area in a large quantity, and the integrity of picture display is ensured.
In order to achieve the above purpose, in step S1, a coordinate system is constructed with the central position of the display screen as the origin of coordinates, the entire display screen is covered comprehensively, so that each light-emitting point on the display screen can obtain unique point coordinates, and the point coordinates are transmitted to the control unit. In this embodiment, firstly, a coordinate establishing module is used to establish coordinates for the whole display screen, and the coordinates are established by using the central position of the display screen as an origin, so that all the light-emitting points can fall into the corresponding coordinate system, and the coordinate system is more convenient to establish and acquire the coordinate values of the light-emitting points; of course, the edge position of the display screen can be used to establish a coordinate system, so as to obtain the coordinates of the light-emitting point.
In step S2, the detection unit is used to detect the light-emitting point, determine whether the light-emitting point can work normally, and transmit the information to the control unit. In this embodiment, if the light-emitting point cannot work due to an accident, the detection unit is used for judging that the light-emitting point cannot work, the coordinate information of the light-emitting point is firstly acquired through the coordinate establishing module, the coordinate information is marked, all information is transmitted to the control unit, and the control unit determines that the light-emitting point cannot work according to the marked information and the coordinate information, so that the display area of the display screen can be adjusted according to the display requirement.
In step S3, the control unit divides the entire display screen into regions according to the usage requirements to obtain different display regions with rectangular structures, then screens the light emitting points in each display region according to the detection information, determines whether the region normally operates according to the ratio of the light emitting points capable of normally operating in the region, and transmits information to the region if the ratio of the region reaches a set threshold value, so that the picture is normally displayed; if and only if the proportion of the luminous points in the area where the luminous points normally work is not less than 95%, information transmission is carried out on the area; in step S3, before performing area division on the display screen, the control unit first acquires and marks coordinates of light emitting points which are recorded in the detection information and cannot normally work, and then judges whether the mark points can form a damaged area, and if the damaged area can be formed, the damaged area is removed before the area division; the manner of judging whether a damaged area can be formed is as follows: acquiring coordinate point information of luminous points which cannot work normally, judging whether the coordinate point information is continuous or not, if so, carrying out set marking on the continuously existing coordinate points, and marking as a damaged area; if the discontinuity exists, it means that a damaged region cannot be formed. In this embodiment, the position of the "bad point" is obtained according to the detection information, then whether a single "bad point" can be collected as a damaged area is judged according to whether the coordinate values between the "bad points" are continuous, after a damaged area is formed, the coordinate information corresponding to the "good point" of the damaged area is recorded and fed back to the control unit, the control unit firstly eliminates the damaged area before area division is performed, then different area division is performed on the remaining areas, and when area division is performed, the "good point" in the area needs to be ensured to reach at least 95% of the ratio, so that excessive loss of information can be avoided in the process of displaying the picture.
In step S4, when information is transmitted to the display areas, selection may be performed according to the number of the display areas, and when only one display area is provided, single-screen display is performed; if the number of the display areas exceeds one, multi-screen display or single-screen display can be carried out.
The working flow of the invention is illustrated below by means of a specific example:
please refer to fig. 2 to fig. 3; firstly, a coordinate dividing unit is used for carrying out coordinate division on all light-emitting points, and then IDs (identity) of the light-emitting points corresponding to coordinate values of position coordinates (x 1, y 1), (x 2, y 2) and (xn, yn) can be known to be respectively; a1, a2, a. Namely, each light-emitting point ID corresponds to the position coordinate, and the light-emitting point is used as a pixel point on the display screen; in the actual use process, for example, an external advertisement screen may be damaged due to the impact of foreign matters, so that the luminous point in a certain area is damaged and cannot work, and becomes a 'dead point'; if the display screen works by adopting the original display scheme, the incomplete display picture can be modeled, in order to avoid the situation, the good points are required to be screened, the bad points are eliminated, the adopted mode is that all the positions of the bad points are collected, a plurality of adjacent bad points are intensively marked to obtain a damaged area, then the damaged area is subjected to area division after being eliminated, the damaged area is divided into a plurality of small areas such as a first area and a second area, each good point can be used as a pixel point for picture display, the control unit can obtain the distribution condition and the number of the good points in the small area according to the detection unit, the ratio between the number of the good points and the number of the actual luminous points is calculated by the control unit, and when the requirement is met, for example, the ratio between the good points and the number of the actual luminous points reaches 95%, the area is judged to be capable of being used as a main area for normal image display, so that the picture is displayed; of course, if two adjacent small regions both satisfy the ratio requirement, the two connected regions will be combined together to form a larger region to be displayed as a whole, and of course, the requirement that the small region a constitutes the large region b needs to satisfy is b =2a; if the small area does not satisfy the requirement, no operation is performed.
For example, the acquired display data is "china", in which the light-emitting point serving as the background color only needs to emit white light all the time, and the light-emitting point serving as the light-emitting point constituting the character needs to emit light of other colors; display coordinates of the light-emitting points as the background color include (Iw 1, jw 1), (Iw 2, jw 2). · Iwn. (Iwn, jwn); the IDs of the corresponding minimum light-emitting points are: aw1, aw2,.. No. awn; display coordinates of the light-emitting dots as the background color include (Ir 1, jr 1), (Ir 2, jr 2.). (Irn, jrn); the IDs of the corresponding light emitting points are respectively: ar1, ar2, no. arw; then, the light emitting point with ID aw1, aw2,.. Awn can emit white light all the time; ID ar1, ar2,. Arw; the luminous point of the LED firstly emits light of other colors; the playing of animation data of China can be realized;
however, if some luminous points are damaged, namely 'dead spots' appear, there is a high possibility that no method is available for forming 'China', and at the moment, screening is needed, and an area meeting the requirements is selected for display; at this time, the display modes are various, the first mode is single-screen display, each area meeting the requirement is used as a display screen for playing, the control unit transmits the information to be played only to the areas for working, the areas not meeting the requirement do not work, and if a plurality of areas exist, the contents displayed by the areas are completely consistent, for example, the areas play 'middle', namely, the areas display 'middle'; the second display mode is multi-screen display, that is, when there are multiple regions meeting the requirements, the content displayed in each region at the same time is different, for example, the first region plays "middle", the second region plays "nation"; the third area plays 'strong', and three characters appear simultaneously; and the control unit can make corresponding information according to specific conditions when the specific playing information is set, so that the luminous point works according to instructions.
The above disclosure is only for a few specific embodiments of the present invention, but the present invention is not limited thereto, and any variations that can be made by those skilled in the art are intended to fall within the scope of the present invention.
