Embodiment 1

[0040] Such as figure 1As shown, the splicing screen 1 includes two mutually spliced ​​display screens 10a and 10b, each display screen 10 is equal in size, and two adjacent display screens 10a and 10b realize seamless splicing, so that the splicing screen 1. Improve user experience when realizing large-screen display. The two display screens 10 a and 10 b are spliced ​​to form a display area 100 , preferably a rectangular display area 100 . The display area 100 includes two reference borders arranged opposite to each other, and the reference line includes a first reference border 21 and a second reference border 22 . The first reference border 21 crosses the display screen 10a and coincides with the border of the display screen 10b. The second reference border 22 crosses the display screen 10b and coincides with the border of the display screen 10a. The display screen 10a has an upper border 101a, and the deviation of the display screen 10a is the width from the first refe...

Embodiment 2

[0070] This embodiment provides a display driving method and a splicing screen display driving system, including most of the technical features of Embodiment 1, the difference being that the splicing screen 1 includes six display screens.

[0071] Such as Figure 5As shown, the splicing screen 1 includes six display screens 10a, 10b, 10c, 10d, 10e, 10f. The first reference border 21 crosses the display screens 10a, 10b and coincides with the border of the display screen 10c. The second reference border 22 crosses the display screens 10e, 10f and coincides with the border of the display screen 10d. Wherein, the display screen 10a has an upper border 101a, and the deviation of the display screen 10a is the width from the first reference border 21 to the upper border 101a; the display screen 10b has an upper border 102b, and the deviation of the display screen 10b is the first The width from a reference border 21 to the upper border 102b; the display screen 10e has a lower bord...

Embodiment 3

[0073] Such as Figure 6 As shown, the splicing screen 1 includes two mutually spliced ​​display screens 10a, 10b, each display screen 10 is equal in size, and two adjacent display screens 10 realize seamless splicing, so that the splicing screen 1 When large-screen display is realized, user experience is improved. Multiple display screens 10 are spliced ​​to form a display area 100 , preferably a rectangular display area 100 . The display area 100 includes two reference borders 2 arranged opposite to each other, and the reference line includes a third reference border 23 and a fourth reference border 24 .

[0074] The third reference border 23 runs through the display screen 10a vertically and coincides with the border of the display screen 10b. The fourth reference border 24 longitudinally passes through the display screen 10a and coincides with the border of the display screen 10b. The display screen 10a has a left border 102a, and the deviation of the display screen 10a...

Abstract

The invention provides a display driving method and a spliced screen display driving system. The display driving method comprises: acquiring the boundary of each display screen; selecting a referenceboundary; according to the reference boundary and the boundary of the display screen, judging whether the physical position of the corresponding display screen relatively deviates or not; if the relative deviation occurs, calculating the deviation amount of each display screen relative to the reference boundary; calculating the deviation row number of the sub-pixels of each display screen according to the deviation amount and the second width, or calculating the deviation column number of the sub-pixels of each display screen according to the deviation amount and the first width; and during display, inputting black picture driving signals into the sub-pixels in the deviation row number or the deviation column number, and inputting normal picture driving signals into the sub-pixels in the area defined by the reference boundary, so that the display picture of the spliced screen is continuous and complete, and the user experience is improved.

Description

technical field [0001] The invention relates to the display field, in particular to a display driving method and a splicing screen display driving system. Background technique [0002] With the continuous development of science and technology, liquid crystal, Micro LED, Mini Led display, AMOLED display and other display technologies emerge in an endless stream. Among them, the display technology of splicing multiple display screens to realize super large display screens is becoming more and more widely used. [0003] When traditional LCD and AMOLED displays realize large displays, they often use small-sized displays to obtain larger displays by splicing, such as 1×2 double-screen splicing, 1×3 three-screen splicing, 2×2 four-screen splicing, etc. Screen splicing and other splicing methods. [0004] Since the production process of the new Micro LED and Mini Led displays is realized by splicing, displays of any size and resolution can be produced, that is, n×n splicing can be...
