具体实施方式
请参阅图1，其为本申请较佳实施例提供的显示系统的亮度调节方法的流程图。所应说明的是，本申请的方法并不受限于下述步骤的顺序，且其他实施例中，本申请的方法可以只包括以下步骤的其中一部分，或者其中的部分步骤可以被删除。此外，在其他实施方式中，一个步骤可以被拆分为多个步骤，或者多个步骤也可以合并为一个步骤。
所述显示系统的亮度调节方法用于调节显示面板透过眼镜的亮度，所述显示面板由背光模块点亮，所述眼镜包括第一镜片及第二镜片，所述显示面板包括多个区块，所述背光模块包括多个发光元件，所述多个发光元件组成背光源；驱动信号包括第一驱动信号及第二驱动信号。所述显示系统的亮度调节方法包括以下步骤：
步骤S1，将第一驱动信号写入显示面板，同时，控制第一镜片开启。
在一个实施例中，所述眼镜为3D液晶眼镜，所述显示面板为3D液晶显示面板。
所述背光源可以是侧入式光源或直下式光源。所述侧入式光源包括单边侧入式光源及双边侧入式光源。控制背光模块的每个发光元件依次开启。在一个显示周期中，驱动信号包括第一驱动信号及第二驱动信号。
如图2所示，在一个实施例中，所述侧入式光源为单边侧入式光源，所述发光元件为LED(Light Emitting Diode，发光二极管)且数量为N个，所述区块与所述LED一一对应，每个LED用于点亮对应一个区块，如，LED1点亮区块BL1，LED2点亮区块BL2，...，LEDN点亮区块BLN。
如图3所示，在一个实施例中，所述侧入式光源为双边侧入式光源，所述发光元件为LED且数量为2N个，每两个LED与一个区块对应，每两个LED点亮对应一个区块，如，LED1A及LED1B点亮区块BL1，LED2A及LED2B点亮区块BL2，...，LEDNA及LEDNB点亮区块BLN。
侧入式光源使用的发光元件数量少，有利于产品减轻重量。
如图4所示，在一个实施例中，所述背光源为直下式光源。所述多个发光元件的数量为N*M个且呈N行、M列的矩阵排布，每一行的M个LED与一个区块对应，每一行的M个LED点亮对应一个区块，所述发光元件为LED。LED1A，LED1B，…，LED1M组成第一行LED背光单元LED1；LED2A，LED2B，…，LED2M组成第二行LED背光单元LED2；…，LEDNA，LEDNB，…，LEDNM组成第N行LED背光单元LEDN。每行LED背光单元用于点亮对应一个区块，如，LED1点亮区块BL1，LED2点亮区块BL2，...，LEDN点亮区块BLN。
直下式光源可以使得显示面板各区块的亮度更均匀。
所述发光元件还可以是CCFL(Cold Cathode Fluorescent Lamp，冷阴极荧光灯管)。
步骤S2，当第一驱动信号写入显示面板的时间达到预设时间时，控制背光模块的每个发光元件依次开启。
当第一驱动信号写入显示面板的时间达到预设时间时，显示面板的穿透率响应稳定且趋于一致，眼镜的穿透率响应稳定且趋于一致。
显示面板各个区块透过液晶眼镜的亮度为显示面板的穿透率、眼镜的穿透率与显示面板的背光平均亮度的乘积。显示面板的背光平均亮度即点亮显示面板的背光源的平均亮度，显示面板的亮度即显示面板显示的亮度。显示面板及眼镜由于液晶响应的物理特性，显示面板及眼镜均需要驱动达到一定的时间才能输出稳定的穿透率，而显示面板的多个区块的背光平均亮度互不相同，若驱动信号写入显示面板及眼镜的开启同步于背光模块的开启，则会使得显示面板的各区块的穿透率、眼镜对应于各区块的穿透率与显示面板的各区块的背光平均亮度的乘积存在差异。因此，可通过驱动信号写入显示面板、眼镜的开启及背光模块的开启的顺序及时间的调整，使得显示面板的各区块的穿透率趋于相等，进而使得显示面板的每个区块的穿透率、每个区块对应的眼镜的穿透率与显示面板的每个区块的背光平均亮度的乘积趋于相等，从而使得显示面板各个区块透过液晶眼镜的亮度均匀。每个区块的背光平均亮度即对应于每个区块的发光元件的平均亮度。每个区块对应的眼镜的穿透率即每个区块对应的发光元件对应的眼镜的穿透率。
本申请在所述背光模块的多个发光元件依次开启的前提下，通过将驱动信号写入显示面板的同时控制第一镜片开启，当第一驱动信号写入显示面板的时间达到预设时间时，再控制背光模块的每个发光元件依次开启，此时， 显示面板的每个区块的穿透率趋于相等及每个区块对应的眼镜的穿透率趋于相等。
步骤S3，调节每个发光元件的第一开启时间。
所述第一开启时间为每个发光元件在显示面板的一个显示周期中，对应于第一驱动信号写入及第一镜片开启的开启时间。
本申请还通过调节每个发光元件的开启时间，进而调节显示面板的每个区块的背光平均亮度，使得显示面板的每个区块的穿透率、每个区块对应的眼镜的穿透率与显示面板的每个区块的背光平均亮度的乘积相等，从而使得显示面板各个区块透过液晶眼镜的亮度均匀。
需要说明的是，在显示面板的一个显示周期中，第一驱动信号写入显示面板，每个发光元件的开启时间达到对应的第一开启时间后关闭。
步骤S4，根据每个区块的背光平均亮度，控制对应的发光元件的开启顺序。
在眼镜开启的初始阶段，眼镜的穿透率较小，随着开启时间的增加，眼镜的穿透率的穿透率逐渐增加并趋于稳定。
在一实施例中，控制背光模块的每个发光元件按其对应的区块的背光平均亮度从高到低的顺序依次开启。
本申请还通过在眼镜的穿透率较小的阶段先开启平均亮度最高的区块对应的发光元件，并在眼镜的穿透率逐渐增大至稳定的过程，按对应的区块的背光平均亮度从高到低的顺序依次开启其余的发光元件，从而使得显示面板的各区块的穿透率、眼镜对应于各区块的穿透率与显示面板的各区块的背光平均亮度的乘积相等，从而使得显示面板各个区块透过液晶眼镜的亮度均匀。
步骤S5，将第二驱动信号写入显示面板，同时，控制第二镜片开启。
步骤S6，当第二驱动信号写入显示面板的时间达到预设时间时，控制背光模块的每个发光元件同时开启。
步骤S7，调节每个发光元件的第二开启时间。
步骤S8，根据每个区块的背光平均亮度，控制对应的发光元件的开启顺序。
所述第二开启时间为每个发光元件在显示面板的一个显示周期中，对应于第二驱动信号写入及第二镜片开启的开启时间。
需要说明的是，在显示面板的一个显示周期中，第二驱动信号写入显示面板，每个发光元件的开启时间达到对应的第二开启时间后关闭。
每个发光元件的驱动电流相等。所述驱动电流用于驱动所述发光元件发光。
为了更好地展现本申请的方法，下面结合图5至图11做具体的说明。请参阅图5，每个发光元件的开启时间分别为t1，t2，...，tN，即对应的每个区块的点亮时间分别为t1，t2，...，tN，t1＝t2…＝tN＝t，其中，t为预设时间。曲线1为写入显示面板的第一驱动信号。曲线2为第一镜片对应于每个发光元件的第一眼镜穿透率，第一镜片对应于每个发光元件的第一眼镜穿透率分别为L_T_1，L_T_2，…，L_T_N。图5前半显示周期的“△”为每个区块对应于每个发光元件的开启时间的第一面板穿透率，每个区块对应于每个发光元件的开启时间的第一面板穿透率分别为OC_TL_1，OC_TL_2，…，OC_TL_N。
图5前半显示周期长方形代表每个区块的背光平均亮度，区块BL1的平均亮度为BL_ave_1，区块BL2的平均亮度为BL_ave_2，...，区块BLN的平均亮度为BL_ave_N。由于背光模块的制造工艺存在差异，BL_ave_1≠ BL_ave_2≠…≠BL_ave_N。此时，用户通过第一镜片看到的显示面板的每个区块的亮度BL_ave_1*OC_TL_1*L_T_1≠BL_ave_2*OC_TL_2*L_T_2≠…≠BL_ave_N*OC_TL_N*L_T_N，即显示面板各个区块透过第一镜片的亮度不均匀。
曲线3为写入显示面板的第二驱动信号。曲线4为第二镜片对应于每个发光元件的第二眼镜穿透率，第二镜片对应于每个发光元件的第二眼镜穿透率分别为R_T_1，R_T_2，…，R_T_N。图5后半显示周期的“△”为每个区块对应于每个发光元件的开启时间的第二面板穿透率，每个区块对应于每个发光元件的开启时间的第二面板穿透率分别为OC_TR_1，OC_TR_2，…，OC_TR_N。图5后半显示周期长方形代表每个区块的背光平均亮度，区块BL1的平均亮度为BL_ave_1，区块BL2的平均亮度为BL_ave_2，...，区块BLN的平均亮度为BL_ave_N。由于背光模块的制造工艺存在差异，BL_ave_1≠BL_ave_2…..≠BL_ave_N。此时，用户通过第二镜片看到的显示面板的每个区块的亮度BL_ave_1*OC_TR_1*R_T_1≠BL_ave_2*OC_TR_2*R_T_2≠…≠BL_ave_N*OC_TR_N*R_T_N，即显示面板各个区块透过第二镜片的亮度不均匀。
请参阅图6至图8，本申请通过将驱动信号写入显示面板的同时控制第一镜片开启，当第一驱动信号写入显示面板的时间达到预设时间时，再控制背光模块的每个发光元件同时开启，并调节每个发光元件的开启时间，进而调节显示面板的每个区块的背光平均亮度，每个发光元件的开启时间分别由t1，t2，...，tN调节至第一开启时间tL1，tL2，...，tLN及第二开启时间tR1，tR2，...，tRN。对应于每个发光元件的第一开启时间，区块BL1的平均亮度由BL_ave_1变为BL_ave_L1’，区块BL2的平均亮度由BL_ave_2变为 BL_ave_L2’，...，区块BLN的平均亮度由BL_ave_N变为BL_ave_LN’。每个区块对应于每个发光元件的开启时间的第一面板穿透率分别由OC_TL_1，OC_TL_2，…，OC_TL_N变为OC_TL_1’，OC_TL_2’，…，OC_TL_N’，OC_TL_1’≈OC_TL_2’…≈OC_TL_N’。第一镜片对应于每个发光元件的第一眼镜穿透率分别由L_T_1，L_T_2，…，L_T_N变为L_T_1’，L_T_2’，…，L_T_N’，L_T_1’≈L_T_2’…≈L_T_N’。此时，用户通过第一镜片看到的显示面板的每个区块的亮度BL_ave_L1’*OC_TL_1’*L_T_1’＝BL_ave_L2’*OC_TL_2’*L_T_2’＝…＝BL_ave_LN’*OC_TL_N’*L_T_N’，即显示面板各个区块透过第一镜片的亮度均匀。
对应于每个发光元件的第二开启时间，区块BL1的平均亮度由BL_ave_1变为BL_ave_R1’，区块BL2的平均亮度由BL_ave_2变为BL_ave_R 2’，...，区块BLN的平均亮度由BL_ave_N变为BL_ave_R N’。第二镜片对应于每个发光元件的第二眼镜穿透率分别由R_T_1，R_T_2，…，R_T_N变为R_T_1’，R_T_2’，…，R_T_N’，R_T_1’≈R_T_2’…≈R_T_N’。每个区块对应于每个发光元件的开启时间的第二面板穿透率分别由OC_TR_1，OC_TR_2，…，OC_TR_N变为OC_TR_1’，OC_TR_2’，…，OC_TR_N’，OC_TR_1’≈OC_TR_2’…≈OC_TR_N’。此时，用户通过第一镜片看到的显示面板的每个区块的亮度BL_ave_R1’*OC_TR_1’*R_T_1’＝BL_ave_R2’*OC_TR_2’*R_T_2’＝…＝BL_ave_R N’*OC_TR_N’*R_T_N’，即显示面板各个区块透过第二镜片的亮度均匀。
请参阅图9至图11，本申请还通过在眼镜的穿透率较小的阶段先开启平均亮度最高的区块对应的发光元件，并在眼镜的穿透率逐渐增大至稳定的过程，按对应的区块的背光平均亮度从高到低的顺序依次开启其余的发光元件， 如图所示，先开启平均亮度最高的区块BL2对应的发光元件，接着开启平均亮度次高的区块BL1对应的发光元件，...，最后开启平均亮度最低的区块BLN对应的发光元件，使得用户通过眼镜观看到的显示面板的每个区块的亮度均匀
