基于上述硬件构架，提出本申请显示面板灰阶电压的生成方法的实施例。
参照图2，图2为本申请显示面板灰阶电压的生成方法的第一实施例，所述显示面板灰阶电压的生成方法包括以下步骤：
步骤S10，数据源集成电路在检测到输入的目标模拟电压时，根据所述目标模拟电压生成预设数量的伽马电压；
在本申请中，显示面板指的是液晶显示面板。显示面板需要多个灰阶电压使得液晶分子进行相应的偏转，使得显示面板显示与图像信号对应的画面。
显示面板包括薄膜晶体管阵列基板，也即TFT（Thin Film Transistor）阵列基板，TFT阵列基板上设置TCON（Timer Control Register）板，TCON板可以产生模拟电压；在本申请中模拟电压设置为连续的、稳定的电压。TCON板可将模拟电压作为目标模拟电压，输入TFT阵列基板中的数据源集成电路（源极集成电路），也即Source IC（Source integrated circuit），使得Source IC可以根据目标模拟电压生成预设数量的伽马电压，预设数量可以为任意合适的数值，可选为14个。各个伽马电压具有对应的序号，比如Gamma1（第一伽马电压），Gamma2等；相邻序号之间的伽马电压具有一定的电压差值，电压差值可在合适的范围内变动，也即技术人员根据需求对电压差值进行调整。需要说明的是，输入的目标模拟电压的稳定性要求比较高，故将TCON板上产生的模拟电压经过处理得到半压的模拟电压，并将该半压的模拟电压作为目标模拟电压输入Source IC中，半压的模拟电压的稳定性优于模拟电压。
Source IC中设有数字控制器（Digital contrlo），数字控制器中设有生成伽马电压的程序，技术人员通过外部烧代码的形式将目标模拟电压与预设序号的伽马电压之间的关系，以及相邻序号的伽马电压的电压差值写入数字控制器，使得数字控制器在检测到目标模拟电压的输入时，采用编程的方式将目标模拟电压通过数字的形式产生预设数量的伽马电压；预设数量一般为14个，为此，数字控制器根据目标模拟电压与预设序号的伽马电压之间的关系以及相邻序号的伽马电压的电压差值，设置14个编程地址，使得数字控制器通过14个编程地址生成14个伽马电压。需要说明的是，目标模拟电压与预设序号的伽马电压之间的关系为Gamma7＞HAVDD＞Gamma8，HAVDD为半压的模拟电压。
可以理解的是，Source IC将目标模拟电压输入数字控制器后，数字控制器即可生成预设数量的伽马电压。
步骤S20，根据各个所述伽马电压生成显示面板的灰阶电压；
Source IC中设有电阻串，在当数字控制器生成伽马电压，Source IC将伽马电压输入电阻串中，以根据电阻串中的电压对伽马电压进行分压，从而得到多个灰阶电压，通过这样的方式，使得Source IC能够根据预设数量的伽马电压生成显示面板的全部灰阶电压。
本申请通过Source IC产生伽马电压，从而省去了设置为产生伽马电压的Gamma IC，由于省去了Gamma IC，使得伽马电压无需占据Source IC的引脚，降低了Source IC的引脚数量，本申请伽马电压的生成成本低。
在本实施例提供的技术方案中，显示面板中的数据源集成电路在检测到输入的目标模拟电压时，根据目标电压生成预设数量的伽马电压，从而根据各个伽马电压生成显示面板的灰阶电压；因数据源集成电路跟根据模拟电压生成伽马电压，省去了设置为生成伽马电压的伽马集成电路，并同时省去了伽马电压占用数据源集成电路中引脚，伽马电压的生成成本低。
参照图3，图3为本申请显示面板灰阶电压的生成方法的第二实施例，基于第一实施例，所述步骤S10包括：
步骤S11，确定相邻序号的伽马电压之间的电压差值，并获取所述目标模拟电压与预设序号的伽马电压之间的关系；
步骤S12，根据所述电压差值以及所述关系，确定所述伽马电压生成电路的参数；
步骤S13，控制所述伽马电压生成电路按照确定的参数运行，并将所述目标模拟电压输入所述伽马电压生成电路，以生成预设数量的伽马电压；
在本实施例中，Source IC中设有伽马电压生成电路，伽马电压生成电路设有多个电阻，Source IC可将目标模拟电压输入伽马生成电路，使得伽马生成电路中的电阻对目标模拟电压进行分压，从而得到预设数量的伽马电压。具体的，Source IC获取相邻序号伽马电压的电压差值，以及目标模拟电压与预设序号的伽马电压的关系，确定伽马电压生成电路中电阻的电阻值，以将电阻所在的电路闭合，各个闭合的电路为串联电路，从而对目标模拟电压进行分压，以得到预设数量的伽马电压。例如，伽马电压生成电路有14组电路，每一组电路设有多个并联的电阻，在对目标模拟电压进行，每一组电路允许一个电路所在的电路闭合，从而得到14个电阻串联的伽马电压生成电路。
可以理解的是，Source IC根据电压差值以及关系确定伽马生成电路的参数，参数指的是各组电路的电阻值；然后，控制伽马电压生成电路按照确定的参数运行，也即将确定的电阻值所在的电路闭合；再将目标模拟电压输入伽马电压生成电路，从而得到预设数量的伽马电压。
另外，伽马电压生成电路可设置放大电路以及缩小电路，Source IC根据电压差值以及关系确定伽马生成电路中放大电路以及缩小电路的参数，从而使得伽马电压生成电路根据放大电路以及缩小电路，将输入的目标模拟电压生成预设数量的伽马电压。
在本实施例提供的技术方案中，数据源集成电路包括伽马电压生成电路，数据源集成电路可以根据目标模拟电压与预设序号的伽马电压之间的关系，以及相邻序号的伽马电压的电压差值来确定伽马生成电路的参数，从而使得运行该参数的伽马电压生成电路将输入的目标模拟电压生成预设数量的伽马电压，省去了设置为生成伽马电压的伽马集成电路，并同时省去了伽马电压占用数据源集成电路中引脚，降低了伽马电压的生成成本。
参照图4，图4为本申请显示面板灰阶电压的生成方法的第三实施例，基于第二实施例，所述步骤S10包括：
步骤S14，根据当前输入的目标模拟电压以及上一次输入的目标模拟电压，判断当前输入的目标模拟电压是否发生变化；
步骤S15，在当前输入的目标模拟电压未发生变化时，执行所述确定相邻序号的伽马电压之间的电压差值，并获取所述目标模拟电压与预设序号的伽马电压之间的关系的步骤。
步骤S16，在当前输入的目标模拟电压发生变化时，确定相邻序号的伽马电压之间的电压差值，并更新当前的目标模拟电压与预设序号的伽马电压之间的关系，以更新所述伽马电压生成电路的参数；
步骤S17，控制所述伽马电压生成电路按照更新的参数运行，并将所述目标模拟电压输入所述伽马电压生成电路，以生成预设数量的伽马电压；
显示面板上的负载的参数发生变化时，会使得TCON板产生的模拟电压产生波动，从而使得目标模拟电压发生波动，使得Source IC产生的灰阶电压不准确，影响显示面板的画面品质。基于此，Source IC会判断当前输入的目标模拟电压以及上一次输入的目标模拟电压之间的差值是否小于预设差值，若是小于预设差值，则判定当前输入的目标模拟电压未发生波动，此时，Source IC执行步骤S11即可；若差值大于或等于预设差值，则判定当前输入的目标模拟电压发生波动，需要调整伽马电压的生成方式，具体的，Source IC中存储有目标模拟电压波动时，目标模拟电压与预设序号的伽马电压之间的关系（该关系与目标模拟电压未波动时对应的关系不同），该关系为Gamma7+n≥HAVDD≥Gamma8-n，n可为任意合适的数值，比如，n为0.2，另外，Source IC还存储有Gamma7与Gamma1的关系，以及Gamma8与Gamma14的关系，
Gamma7与Gamma1的关系为：Gamma1- Gamma7=x±m，Gamma8与Gamma14的关系为Gamma8- Gamma14=x±m，其中，x与m为任意合适的数值，比如x为7，m为0.1。
Source IC根据上述三种关系，以及电压差值来更新伽马电压生成电路的参数，从而使得伽马电压生成电路生成预设数量的伽马电压。
需要说明的是，在一实施例中，伽马电压由Source IC中的数字控制器生成，数字控制器也许判断当前输入的目标模拟电压是否发生变化，若是变化，则采用三种关系以及电压差值重新编码，以生成对应的伽马电压。
在本实施例提供的技术方案中，在检测到当前输入的目标模拟电压发生变化时，更新伽马电压生成电路的参数，以根据变化的目标模拟电压生成伽马电压，从而准确的生成显示面板的灰阶电压。

所述存储器存储有可被所述至少一个处理器执行的计算机可执行指令，所述计算机可执行指令被所述至少一个处理器执行时，使得一个处理器执行以下步骤：
