Embodiment Construction

[0021] Certain terms are used in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Includes" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means.

[0022] Please refer to figure 2 , which is a schematic diagra...

Abstract

The invention relates to a method for controlling a display array. In order to solve the technical problem, the method for controlling the display array is provided. The display array comprises a plurality of displays; and the method for controlling the display array comprises the following steps of: controlling each display in the display array to generate a first brightness output value respectively according to a plurality of first brightness control value; controlling each display in the display array to generate a second brightness output value respectively according to a plurality of second brightness control value, wherein the first brightness control value and the second brightness control value which control the same display are different; determining a characteristic relation corresponding to each display respectively according to the plurality of first brightness output values and the plurality of second brightness output values; and controlling each corresponding display in the display array according to each characteristic relation.

Description

【Technical field】 [0001] The invention relates to a control method of a display array, in particular to a control method for maintaining the brightness consistency of an output picture of the display array. 【Background technique】 [0002] In outdoor occasions or display occasions, displays will be spliced ​​in arrays for image output, which is commonly known as a video wall. This display array can provide several times the display range that a single display can provide, and its schematic diagram is shown in figure 1 A display array 100 is shown. In order to ensure the uniformity and consistency of the displayed picture, the display array is generally composed of displays with the same display characteristics (such as: contrast, brightness, color scale, etc.). Although the inherent characteristic differences of displays have been taken into consideration in the original design, there are still the following problems in practical applications. [0003] First, due to manufa...
