[0038] 为使本发明的目的、技术方案和优点更加清楚明白,以下举实施例并参照附图,对本发明进一步详细说明。 [0038] To make the objectives, technical solutions, and advantages of the present invention will become apparent from the following embodiments and with reference to the accompanying drawings, the present invention is further described in detail.

[0039] 如图1所示,一种控制显示装置背光源的方法,该方法包括以下步骤: [0039] 1, A method of controlling a backlight display device, the method comprising the steps of:

[0040] 步骤100、依据显示装置背光源的阵列布置,预设置显示区域划分参数和目标显示参数。 [0040] Step 100, the array is arranged according to the display device backlight, display area into a pre-set target parameters and display parameters.

[0041] 这里,显示装置可以为LED背光源的显示装置,以及等同于或类似于LED背光源显示和发光机制的显示装置。 [0041] Here, a display device and a light emitting device display mechanism may display an LED backlight device and the LED backlight display identical or similar.

[0042] 这里,区域划分参数为依据背光源的数量和排列将显示装置进行划分的参数,比如画面区域划分方式;目标显示参数是指对待显示数据的显示要求参数,比如亮度参数、和/或对比度参数、和/或颜色参数。 [0042] Here, zoning parameters the number and arrangement based on a backlight display device parameters division, such as a screen region division manner; target display parameter is the display request parameters to treat the display data, such as brightness parameter, and / or contrast parameters, and / or color parameter. 为了后续操作简单易用起见,可以将区域划分参数和目标显示参数放置到模板中存储,这个模板可以称为背光模板,那么背光模板中存储的参数包括:画面区域划分方式、和/或亮度参数、和/或对比度参数、和/或颜色参数。 For the sake of the subsequent operation easy to use, and zoning certain parameters can be placed into the display parameters stored in the template, the template may be called a backlight template, the template parameters stored in the backlight comprising: a screen region division manner, and / or brightness parameters and / or contrast parameters, and / or color parameter. 并且建立的背光模板包括:自然背光模板、色彩鲜艳背光模板、提升对比度背光模板和用户自定义的模板。 And establishing backlight template comprises: a template NATURAL backlight, the backlight colorful template, to enhance the contrast of the backlight and the user-defined templates. 建立的背光模板存储在显示器上。 The templates are stored in the establishment of the backlight on the display.

[0043] 其中,针对背光模板而言,举例来说,图2为本发明背光模板数据格式一实施例的示意图。 [0043] wherein, for the purposes of the backlight template, for example, FIG. 2 is a schematic diagram of an embodiment of a data format template backlight invention. 图2中,背光模板数据格式包括背光模板的名称和背光模板中存储的参数。 In FIG. 2, the backlight data format template comprising a template of the backlight and the backlight parameter names stored in the template. 其中, 背光模板中存储的参数包括画面区域划分方式、对比度参数和颜色参数。 Wherein, the parameters stored in the template comprises a backlight screen region division manner, the color contrast parameters and parameter.

[0044] 步骤101、获取待显示数据,获取预设置的显示区域划分参数,获取预设置的目标显示参数;依据显示区域划分参数,将待显示数据划分为M个待显示数据块。 [0044] Step 101, acquires data to be displayed, acquisition of the display area into a preset parameter acquiring preset target display parameters; parameter based display area into the data to be displayed is divided into M blocks of data to be displayed.

[0045] 当将区域划分参数和目标显示参数放置到背光模板中存储时,且区域划分参数具体为:画面区域划分方式,则步骤101中,依据显示区域划分参数,将待显示数据区域划分为M个待显示数据块具体为:依据画面区域划分方式对待显示数据进行区域划分,划分为M 个待显示数据块,且M为大于或等于二的整数;当所述显示装置为发光二极管LED背光源的显示装置时,M ( LED灯的个数。 [0045] When the area division parameter and the target display parameters placed into the backlight stored template, and the area is divided parameters specifically: screen region division manner, then the step 101, based on display area into the parameter, the data to be displayed area into the M block of data to be displayed specifically: dividing a screen area basis treating displayed area division data, is divided into M blocks of data to be displayed, and M is an integer greater than or equal to two; when the display device is a light emitting diode (LED) backlighting when the source of the display device the number, M (LED lamp.

[0046] 这里,该画面区域划分方式为非矩形划分的方式,也就是说画面区域划分方式不限于矩形划分的方式。 [0046] Here, the non-rectangular screen region division manner division manner, that is to say the picture is divided is not limited to a rectangular region dividing manner. 举例来说,非矩形划分的方式包括菱形划分的方式、圆形划分的方式或者蜂窝形划分的方式。 For example, non-rectangular partitioning methods include diamond-divisional manner, a divided manner or a circular-shaped honeycomb-divisional manner. 画面区域划分方式的选取原则是:区域划分的方式要保持LED背光的均勻性。 Selection principle is a screen region division mode: region division manner to maintain uniformity of the LED backlight. 举例来说,如果不遵循这个选取原则的话,会导致某些区域中,一部分亮度大, 一部分亮度小,那么整体区域亮度就不均勻了。 For example, if the selection does not follow this principle, it will result in certain areas, a portion of high brightness, low luminance portion, the entire region of the brightness is not uniform. 从而导致画面显示效果降低,影响画面显示效果。 Resulting in reduced screen display, affect the picture display.

[0047] 图3为本发明画面划分一实施例的示意图,如图3所示,当采用矩形划分的方式, 整幅显示画面区域被划分为多个矩形区域。 Screen [0047] FIG. 3 is an embodiment of the divided schematic diagram of an embodiment, shown in Figure 3, when the divided rectangular manner, the whole display region is divided into a plurality of rectangular regions. 如果采用菱形划分的方式,则整幅显示画面区域被划分为多个菱形区域。 If the diamond-divisional manner, the entire display area is divided into a plurality of diamond-shaped areas.

[0048] 步骤102、对M个待显示数据块进行显示分析,对应的获得M个待显示参数;从M个待显示参数中,检测并获取未满足目标显示参数的N个待显示参数。 [0048] Step 102, the M data to be displayed on the display block analysis, corresponding to obtain M parameters to be displayed; from the M parameters to be displayed, and acquires the detection is not satisfied the N target display parameters to be displayed parameters.

[0049] 这里,N为整数且0 < N < M。 [0049] Here, N is an integer and 0 <N <M. 那么,检测并获取满足目标显示参数的待显示参数为MN个,其对应MN个待显示数据块。 So, to meet the target detected and acquires parameters to be displayed as display parameters of MN, which corresponds to data to be displayed the block of MN. 由于只需将未满足目标显示参数的N个待显示参数进行动态调整,而满足目标显示参数的MN个待显示参数无需做调整,因此,后续步骤103中, 针对这MN个待显示数据块,也就是M个待显示数据块中除去N个的待显示数据块而言,只需控制M个待显示数据块中除去N个的待显示数据块对应的背光源,按照显示分析后的待显示参数显示。 Because only the display of the N does not satisfy the target parameter display parameters to be adjusted dynamically while the MN to be displayed to meet the target display parameters without making parameter adjustments, therefore, the subsequent step 103, the display data block for this to be the MN, the M is to be displayed to be displayed by removing N data blocks, only M of the control to be displayed to remove the N blocks of data to be displayed corresponding to the backlight data block in the data block, to be displayed in the display analysis parameter display. 这里,由于显示分析后的待显示参数已经与目标显示参数相符合了,因此无需做调整。 Here, since the display to be displayed after the analysis parameters have been consistent with the target display parameters, so no need to make adjustments.

[0050] 这里,当将区域划分参数和目标显示参数放置到背光模板中存储时,且目标显示参数具体为:亮度参数、和/或对比度参数、和/或颜色参数时,则步骤102中,对M个待显示数据块进行显示分析具体为:依据所述亮度参数、和/或所述对比度参数、和/或所述颜色参数对所述M个待显示数据块进行显示分析,且M为大于或等于二的整数。 [0050] Here, when the area division parameter and the target display parameters placed backlight templates are stored, and the target display parameters specifically: a brightness parameter, and / or contrast parameters, and / or color parameters, then the step 102, displaying the M blocks of data to be analyzed specifically displayed as follows: according to the brightness parameter, and / or the contrast parameter and / or the color of the M parameters to be analyzed to display the display data block, and M is an integer greater than or equal to two. 以便于后续步骤103中,可以实现控制显示区域中背光源所在区域的目标背光显示。 In order to facilitate the subsequent step 103, control can be achieved target backlight display area of ​​the backlight display Area. 其中,目标背光显示指不同LED背光源所在区域的亮度、和/或对比度、和/或颜色。 Wherein the display means a target backlight luminance area where the different LED backlight, and / or contrast and / or color.
