Description
Technical Field
The invention relates to the technical fields of optoelectronics and information display, in particular to an arrangement structure of luminous components.
Background
The display screen is an important man-machine interaction medium, is as small as an intelligent watch/bracelet, and is as large as intelligent equipment such as a display screen for display, a display screen for conference, an advertisement screen and the like, and then is used as the man-machine interaction medium; in the prior art, the display screen commonly used mainly has two technical routes of LCD and OLED, in addition, miniLED and MicroLED display technologies are also rapidly developed, and for large-scale display screens, LED display technologies are adopted.
The LED display technology has the advantages of wide color gamut, high luminous efficiency, high response speed, wide working temperature range and the like, is widely applied to the fields of high-end display, flat panel display backlight source, illumination and the like, and has wide application markets in the fields of cinema, medical teaching and the like. In recent years, with the development of technology, high-density and ultra-high-density LED display screens are gradually developed; the high-density LED display screen can be applied to ultra-large high-image-quality televisions.
An important indicator affecting the image quality of the high-density LED display screen is screen sharpness. The screen definition is mainly embodied in aspects of image spatial resolution, image display hierarchical resolution, pixel optical crosstalk degree, pixel edge fusion degree and the like; the spatial resolution of the image depends on the arrangement of the LED pixels and the pixel density in the LED display screen.
In short, the arrangement mode (or called pixel arrangement structure or pixel structure) of the LED pixels has an important influence on the display effect of the high-density LED display screen. In addition, the pixel arrangement structure has decisive influence on the performances of the LED display screen, such as brightness, response speed, color quality, service life and the like.
The prior Chinese patent No. CN205231067U discloses a pixel unit, a pixel structure and a display. The pixel structure disclosed in said patent CN205231067U comprises a plurality of repeating structures; each repeating structure is composed of two rows of pixel unit groups, namely a first pixel unit group and a first pixel unit group; wherein, the sub-pixels in the two rows of pixel unit groups are arranged in a staggered way. In the pixel structure of the utility model patent CN205231067U, as the same sub-pixels of the adjacent pixel sub-units are adjacent, the open pores of the vapor plating mask plate are increased, and the process difficulty is reduced; meanwhile, the shapes of the green pixel, the blue pixel and the red pixel are the same, so that the pixels (the sub-pixels, the sub-pixels or the light-emitting components) with three colors (namely three primary colors) can share the same metal mask plate for evaporation, and the manufacturing difficulty and the manufacturing cost of the mask plate are further reduced.
However, the pixel structure of said patent CN205231067U also has some drawbacks: the pixel structure takes two rows of pixel unit groups as a repeated structure; in the longitudinal direction (or column direction) of each repeating structure, only two sub-pixels participate in color mixing, so that serious color cast problems and even color edges occur.

Embodiment six, the present embodiment is described with reference to fig. 2-3, and provides a display control method:
the display control method is used for controlling the display of the arrangement structure of the light-emitting components;
the method comprises the following steps:
s1, determining source pixel points of driving signals of each light emitting component in an arrangement structure; wherein the source pixel point comprises primary color display data; the primary color display data comprises first primary color display data, second primary color display data and third primary color display data;
n is a positive integer greater than 2:
the source pixel point of the driving signal of the light emitting component of the 1 st row and the j th column is the pixel point of the 1 st row and the j th column in the video source;
the source pixel point of the driving signal of the light emitting component of the 2 nd row and the j th column is the pixel point of the 1 st row and the j th column in the video source;

s2, processing primary color display data of source pixel points of driving signals of each light-emitting component to obtain the driving signals of each light-emitting component;
s3, acquiring addresses of the light emitting components corresponding to each driving signal, and sending the driving signals to the corresponding light emitting components;
specifically, the address of the light emitting part corresponding to each driving signal is obtained through the positional relationship of the light emitting part and the pixel point from which the light emitting part originates.
In this embodiment, determining the source pixel of the driving signal of each light emitting component corresponds to determining which light emitting component is multiplexed (or corresponds to) with each row of pixels in the video source:
this correspondence or multiplexing relationship may be understood in the manner of virtual pixels.
Based on the arrangement structure, a virtual pixel structure is constructed:
the virtual pixel structure comprises a plurality of virtual pixel units; each virtual pixel unit consists of three adjacent light-emitting components in the same column;
for example, as can be seen from fig. 2, 3 light emitting elements of the 1 st row, the 1 st column, the 1 st row, the 2 nd column, and the 1 st row, the 3 rd column constitute a virtual pixel unit; the 3 light emitting components of the 1 st row, the 2 nd column, the 1 st row, the 3 rd column and the 1 st row, the 4 th column form another virtual pixel unit; the 3 light emitting components of the 1 st row, the 3 rd column, the 1 st row, the 4 th column and the 1 st row, the 5 th column also form another virtual pixel unit;
each virtual pixel unit can be regarded as the mapping of each row of pixel points in the video source in the arrangement structure;
for example:
the virtual pixel unit composed of 3 light emitting components of the 1 st row, the 1 st column, the 1 st row, the 2 nd column and the 1 st row and the 3 rd column can be called as a virtual pixel unit positioned in the 1 st row and the 1 st column in the arrangement structure, and corresponds to the 1 st row and the 1 st column pixel point in the video source;
the virtual pixel unit composed of 3 light emitting components of the 1 st row, the 2 nd column, the 1 st row, the 3 rd column and the 1 st row, the 4 th column can be called as a virtual pixel unit positioned in the 2 nd row and the 1 st column in the arrangement structure, and corresponds to the pixel point of the 2 nd row and the 1 st column in the video source;
The virtual pixel unit composed of 3 light emitting components of the 1 st row, the 3 rd column, the 1 st row, the 4 th column and the 1 st row, the 5 th column can be called as a virtual pixel unit positioned in the 3 rd row and the 1 st column in the arrangement structure, and corresponds to the pixel point of the 3 rd row and the 1 st column in the video source;
meanwhile, according to the drawing, the light emitting components corresponding to the 1 st row and 1 st column pixel points in the video source are 3 light emitting components of the 1 st row and 1 st column, the 1 st row and 2 nd column and the 1 st row and 3 rd column; the light-emitting components corresponding to the pixel points of the 2 nd row and the 1 st column in the video source are 3 light-emitting components of the 1 st row and the 2 nd column, the 1 st row and the 3 rd column and the 1 st row and the 4 th column; the light emitting components corresponding to the pixel points of the 3 rd row and the 1 st column in the video source are 3 light emitting components of the 1 st row and the 3 rd column, the 1 st row and the 4 th column and the 1 st row and the 5 th column.
From the above, it can be seen that:
in the arrangement structure, each column of virtual pixel units consists of light emitting components in the same column, and the light emitting components in a certain column are multiplexed by a certain number of virtual pixel units in the same column;
specifically, referring to fig. 2, taking the first column as an example:
the 1 st column and 1 st row red light emitting component can only be regarded as a component part of the 1 st row and 1 st column virtual pixel units and is not multiplexed by other virtual pixel units, so that the source pixel point (corresponding pixel point) of a driving signal is the 1 st row and 1 st column pixel point in a video source, and the required same primary color output data (red output data) is red primary color (red component) display data of the 1 st row and 1 st column pixel point;
The green light emitting component of the 1 st column and the 2 nd row can be regarded as a component part of the 1 st row and the 1 st column or the 2 nd row and the 1 st column virtual pixel units, namely, the component part is multiplexed by the 1 st row and the 1 st column and the 2 nd row and the 1 st column virtual pixel units, so that the source pixel point of a driving signal is the 1 st row and the 1 st column and the 2 nd row and the 1 st column pixel points in a video source, and the required green output data is the average value of green component display data of the 1 st row and the 1 st column and the 2 nd row and the 1 st column pixel points;
