Description

一种液晶面板的驱动电路、 液晶面板和液晶显示装置
【技术领域】
本发明涉及显示屏领域， 更具体的说， 涉及一种液晶面板的驱动电路、 液 晶面板和液晶显示装置。
【背景技术】
目前关于液晶面板的驱动的一般的印刷电路板架构由系统板（ SOC Board ) , 控制板（C/B )，源极驱动板（ SOURCE Board )组成。 系统级芯片负责视频信号 的产生， 控制板（C/B )主要是负责视频信号转换和同步信号的产生 (主要由时 序控制芯片来实现） ，控制板（C/B )上还有 DC/DC 电源模块（产生给 panel 的 电压和时序控制模块芯片电压）和 P-gamma模块 (可编程伽玛校正緩沖电路晶 片）， 源极驱动板 ( SOURCE Board )主要负责驱动 gate/source 芯片。 现在的液 晶面板厂家想要获得强大的竟争力， 生产成本上的优势的获取是至关重要的。
【发明内容】
本发明所要解决的技术问题是提供一种降低成本的液晶面板的驱动电路、 液晶面板和液晶显示装置。
本发明的目的是通过以下技术方案来实现的：
一种液晶面板的驱动电路， 该驱动电路包括与液晶面板的阵列基板直接电 连接的源极驱动板， 所述的驱动电路还包括转换视频信号和产生同步信号的时 序控制模块、 电压转换模块和伽玛模块， 所述的时序控制模块、 电压转换模块 和伽玛模块集成在所述的源极驱动板上。 进一步的， 所述的源极驱动板包括源 极驱动左板和源极驱动右板， 所述的源极驱动左板和源极驱动右板耦合； 所述 的时序控制模块、 电压转换模块和伽玛模块均设置在源极驱动右板上。 将时序 控制模块、 电压转换模块和伽玛模块都设置在源极驱动板上， 由于将过驱动模 块移到系统级芯片处， 可以比较方便的将封装面积减小的时序控制模块、 以及 电压转换模块和伽玛模块直接设置在源极驱动板（ SOURCE Board )上， 省去一 块控制板（C/B ), 这样做可以节省制板成本， 提高竟争力， 同时将伽玛模块做 在源极驱动板 ( SOURCE Board )上可实现 gamma和液晶面板的绑定， 若出现 非伽玛模块异常， 需要调整 gamma时， 只需要更换系统板（ SOC Board ) 即可， 无需进行 gamma调整， 节省人力成本和时间。
所述的源极驱动板包括源极驱动左板和源极驱动右板， 所述的源极驱动左 板和源极驱动右板耦合； 所述的时序控制模块设置在所述的源极驱动右板上， 所述的电压转换模块和伽玛模块设置在源极驱动右板设置在源极驱动左板上。 将时序控制模块、 电压转换模块和伽玛模块都设置在源极驱动板上， 省去一块 控制板（C/B ), 这样做可以节省制板成本， 提高竟争力； 而将时序控制模块设 置在与系统及芯片直接电连接的源极驱动右板， 将电压转换模块和伽玛模块设 置在源极驱动左板上， 使得时序控制模块与系统及芯片能够更好的耦合， 同时 将制版面积的需要分摊到两块板上， 能够使得设置更为合理， 避免其中一块源 极驱动板太小而另一块太大， 不协调而难以设置的情况。 源极驱动左板和源极驱动右板耦合； 所述的时序控制模块和电压转换模块设置 在所述的源极驱动右板上， 所述的伽玛模块设置在所述的源极驱动左板上。 将 时序控制模块、 电压转换模块和伽玛模块都设置在源极驱动板上， 省去一块控 制板（C/B ), 这样做可以节省制板成本， 提高竟争力， 而单独将伽玛模块设置 在元极驱动左板上， 是因为伽玛模块主要用于生成 gamma电压， 用于数据信号 的的校准， 而时序控制模块和电压转换模块则需要负责栅线和数据线两方面的 工作， 将两者分别设置可以使得布线更为方便， 避免布线复杂使得制作工艺难 度升高， 继而增加人力物力成本的情况。 源极驱动左板和源极驱动右板耦合； 所述的时序控制模块和伽玛模块设置在所 述的源极驱动右板上， 所述的电压转换模块设置在所述的源极驱动左板上。 将 时序控制模块、 电压转换模块和伽玛模块都设置在源极驱动板上， 省去一块控 制板（C/B ), 这样做可以节省制板成本， 提高竟争力； 电压转换模块的产热相 对较多， 且其制板面积比伽玛模块和面积减小后的时序控制模块来说要大， 将 其单独设置在源极驱动左板上， 可以避免电压转换模块产生的热量对所述的时 序控制模块， 以及伽玛模块造成不必要的影响， 改善电压转换模块的散热情况， 同时使得制板布局更为合理， 方便制板。
一种液晶面板， 该液晶面板包括本发明的驱动电路， 还包括系统板， 所述 的系统板包括用于生成视频信号的系统级芯片， 所述的系统板直接电连接于所 述的源极驱动板。 将时序控制模块、 电压转换模块以及伽玛模块设置在源极驱 动板（ SOURCE Board )上， 且源极驱动板 ( SOURCE Board )和系统板直接电 连接， 而省去了原本在两者之间的控制板（C/B ), 节省了生产的成本。 时序控制模块、 电压转换模块和伽玛模块分别设置在源极驱动左板或源极驱动 右板上， 所述的系统板和时序控制模块所在的源极驱动板通过柔性电路板直接 电连接， 所述的柔性电路板包括差分信号线。 将时序控制模块、 电压转换模块 和伽玛模块分别设置在源极驱动左板或源极驱动右板上能够节省一块板的成 本； 而将伽玛模块设置在源极驱动板上可实现 gamma和液晶面板的绑定， 若出 现非伽玛模块异常， 需要调整 gamma 时， 只需要更换系统板即可， 无需进行 gamma调整， 节省人力成本和时间。
进一步的， 所述系统板包括用于生成视频信号的系统级芯片， 所述的驱动 电路还包括用于提高液晶反应效率的过驱动模块， 所述的过驱动模块设置在所 述的系统级芯片上；
所述的过驱动模块上设置有具备存储功能的存储芯片， 所述的存储芯片存 储有过驱动模块的用于实现提高液晶反应效率的过驱动功能的表单元。 完成提 高液晶反应效率的过驱动功能需要存储芯片的存储表单元， 表单元提供最佳相 应响应时间对照， 协助利用电场加速效应， 在两个帧之间插入另一个帧， 施加 较高补偿电压， 强迫液晶分子在较短时间内改变排列， 从低亮灰阶达到预定的 高亮灰阶， 从而提升液晶的响应时间； 而该存储芯片占据的面积较大， 将过驱 动模块移到系统板（SOC Board )实际上主要是减少存储芯片在时序控制模块中 占据的面积， 从而减小时序控制模块的封装面积， 使得时序控制模块需求的制 版面积变小， 可以方便时序控制模块设置在制板面积较小的地方； 另外， 原本 时序控制模块和系统级芯片都设置有过驱动模块， 现在将两者的过驱动模块统 合起来， 集成到系统级芯片上， 如此对于整个制版的需求来说， 时序控制模块 减少的部分， 比系统级芯片增加的部分要多， 因而整体制板减小， 降低了成本。
进一步的， 所述的时序控制模块上设置有第一高速低压差分接口， 所述的 系统板上设置有与所述第一高速低压差分接口相配合的第二高速低压差分接 口， 所述的第一高速低压差分接口和第二高速低压差分接口通过差分信号线相 连接。目前 3D模式下，业界通常的做法是输入 60HZ低压差分信号，经 TCON处 理后输出 120HZ 3D画面， 这种处理以降低解析度为代价； TCON接口改为高速 低压差分接口（ high speed LVDS )，在差分走线 pair数不变的情况下，实现 120 HZ 输入， 120HZ输出，实现了 3D模式下不会降低解析度。
一种液晶显示装置， 包括本发明所述的液晶面板。 使用所述的驱动电路的 液晶显示装置， 能够有效的减少生产成本。
经研究发现， 液晶面板的驱动电路， 其中一个主要的成本来自于电路板， 现在一般来说驱动电路主要包括系统板（ SOC Board ) , 控制板（ C/B )和源极驱 动板 (SOURCE Board), 这三块板占据了相当的生产成本， 本发明由于直接将原 来设置在控制板（C/B )上的时序控制模块、 电压转换模块和伽玛模块设置在源 极驱动板 (SOURCE Board)上， 而省去了控制板（ C/B ), 如此能够节省生产成本。

图 3是本发明一种液晶面板实施例二的示意图；
图 4是本发明一种液晶面板实施例三的示意图；
图 5是本发明一种液晶面板实施例四的示意图。
【具体实施方式】
图 1是本发明一种液晶面板的驱动电路、液晶面板和液晶显示装置的示意图， 该液晶显示装置 90包括液晶面板 100, 该液晶面板 100包括驱动电路 120、 阵 列基板 110和系统板 1 ,驱动电路 120包括与阵列基板 110直接电连接的源极驱 动板 2,所述的驱动电路 120还包括转换视频信号和产生同步信号的时序控制模 块 TCON、 电压转换模块 DC/DC和生成用于影像灰阶亮度修正的 gamma电压 的伽玛模块 P-G, 所述的时序控制模块 TCON、 电压转换模块 DC/DC和伽玛模 块 P-G集成在所述的源极驱动板 2上。
经研究发现， 液晶面板的驱动电路， 其中一个主要的成本来自于电路板， 而 现在一般来说液晶面板主要包括系统板（ SOC Board ) , 控制板（ C/B )和源极驱 动板 (SOURCE Board), 这三块板占据了相当的生产成本， 本发明由于直接将原 来设置在控制板（C/B )上的时序控制模块、 电压转换模块和伽玛模块设置在源 极驱动板 (SOURCE Board)上， 而省去了控制板（ C/B ), 如此能够节省生产成本。
下面结合附图和较佳的实施例对本发明作进一步说明。
图 2是本发明一种液晶面板实施例一的示意图， 该液晶面板包括负责视频信 号的产生的系统板 1和驱动液晶面板数据线的源极驱动板 2,其中系统板 1包括 系统级芯片 SOC; 而源极驱动板 2包括源极驱动左板 XL、耦合于源极驱动左板 XL的源极驱动右板 XR和设置在源极驱动右板上的时序控制模块 TCON, 所述 的系统板 1和源极驱动右板 XR上的时序控制模块 TCON直接电连接； 源极驱 动右板 XR上还设置有电压转换模块 DC/DC和生成用于影像灰阶亮度修正的 gamma电压的伽玛模块 P-G。 将时序控制模块、 电压转换模块和伽玛模块都设 置在源极驱动板上， 一则能够将原来需要的控制板 （C/B ) 和源极驱动板 ( SOURCE Board )减少为只使用源极驱动板（ SOURCE Board ), 省去了控制板 ( C/B ),节省了生产的成本；二则， 由于不同的液晶面板特性不一样， gamma也 不一样， 一个液晶面板对应一个 gamma,当产品做出来之后， 一旦非伽玛模块出 现异常， 需要解析或重工时， 如果伽玛模块设置在系统板（SOC Board )上,需要 对 gamma重新调整时， 只需更换系统板（ SOC Board ) 即可， 无需进行 gamma 调整， 节省人力成本和时间。
如上所述的系统级芯片 S0C还包括过驱动模块 0D, 过驱动模块 0D上设置 有具备存储功能的存储芯片 FLA, 所述的存储芯片 FLA存储有过驱动模块用于 完成提高液晶反应效率的过驱动功能的表单元 11。 完成提高液晶反应效率的过 驱动功能需要存储芯片的表单元， 表单元提供最佳相应响应时间对照， 协助利 用电场加速效应， 在两个帧之间插入另一个帧， 施加较高补偿电压， 强迫液晶 分子在较短时间内改变排列， 从低亮灰阶达到预定的高亮灰阶， 从而提升液晶 的响应时间； 而该存储芯片占据的面积较大， 将过驱动模块移到系统板（SOC Board ) 实际上主要是减少存储芯片在时序控制模块中占据的面积， 从而减小时 序控制模块的封装面积， 使得时序控制模块需求的制版面积变小， 可以方便时 序控制模块设置在制板面积较小的地方； 另外， 原本时序控制模块和系统级芯 片都设置有过驱动模块， 现在将两者的过驱动模块统合起来， 集成到系统级芯 片上， 如此对于整个制版的需求来说， 时序控制模块减少的部分， 比系统级芯 片增加的部分要多， 因而整体制板减小， 降低了成本。
如上所述的系统板 1和时序控制模块 TCON所在的源极驱动右板 XR通过柔 性电路板 2直接电连接，柔性电路板 3包括差分信号线 31;时序控制模块 TCON 上设置有第一高速低压差分接口 32, 所述的系统板 1上设置有与第一高速低压 差分接口相配合的第二高速低压差分接口 33,第一高速低压差分接口 32和第二 高速低压差分 33接口通过差分信号线 31相连接。 目前 3D模式下， 业界通常的 做法是输入 60HZ低压差分信号，经 TCON处理后输出 120HZ 3D画面， 这种处 理以降低解析度为代价； TCON接口改为高速低压差分接口（ high speed LVDS ) , 在差分走线 pair数不变的情况下， 实现 120 HZ输入， 120HZ输出，实现了 3D 模式下不会降低解析度。
图 3是本发明一种液晶面板实施例二的示意图， 该液晶面板包括负责视频信 号的产生的系统板 1和驱动液晶面板数据线的源极驱动板 2,其中系统板 1包括 系统级芯片 SOC, 所述的系统级芯片 SOC包括设置有存储芯片 FLA的过驱动 模块 OD; 而源极驱动板 2包括源极驱动左板 XL、 耦合于源极驱动左板 XL的 源极驱动右板 XR以及设置在源极驱动右板 XR上的时序控制模块 TCON,所述 的系统板 1和源极驱动右板 XR上的时序控制模块 TCON直接电连接； 该液晶 面板还包括电压转换模块 DC/DC和生成用于影像灰阶亮度修正的 gamma电压 的伽玛模块 P—G, 电压转换模块 DC/DC和伽玛模块 P-G设置在源极驱动左板 XL。 将时序控制模块、 电压转换模块和伽玛模块都设置在源极驱动板上， 由于 将过驱动模块移到系统级芯片处， 可以比较方便的将封装面积减小的时序控制 模块、 电压转换模块和伽玛模块直接设置在源极驱动板（ SOURCE Board )上， 省去一块控制板（C/B ), 这样做可以节省制板成本， 提高竟争力， 同时将伽玛 模块做在源极驱动板（SOURCE Board )上可实现 gamma和液晶面板的绑定， 若出现非伽玛模块异常， 需要调整 gamma时， 只需要更换系统板（ SOC Board ) 即可， 无需进行 gamma调整， 节省人力成本和时间； 而将时序控制模块设置在 与系统及芯片直接电连接的源极驱动右板， 将电压转换模块和伽玛模块设置在 源极驱动左板上， 使得时序控制模块与系统级芯片能够更好的耦合， 同时将制 版面积的需要分摊到两块板上， 能够使得设置更为合理， 避免其中一块源极驱 动板太小而另一块太大， 不协调而难以设置的情况。
图 4是本发明一种液晶面板实施例三的示意图， 该液晶面板包括负责视频信 号的产生的系统板 1和驱动液晶面板数据线的源极驱动板 2,其中系统板 1包括 系统级芯片 SOC, 所述的系统级芯片 SOC包括设置有存储芯片 FLA的过驱动 模块 OD; 而源极驱动板 2包括源极驱动左板 XL、 耦合于源极驱动左板 XL的 源极驱动右板 XR和设置在源极驱动右板 XR上的时序控制模块 TCON,所述的 系统板 1和源极驱动右板 XR上的时序控制模块 TCON直接电连接； 该液晶面 板还包括电压转换模块 DC/DC和生成用于影像灰阶亮度修正的 gamma电压的 伽玛模块 P-G, 其中伽玛模块 P-G设置在源极驱动左板 XL, 而电压转换模块 DC/DC设置在源极驱动右板 XR。 将时序控制模块、 电压转换模块和伽玛模块 都设置在源极驱动板上， 由于将过驱动模块移到系统级芯片处， 可以比较方便 的将封装面积减小的时序控制模块、 电压转换模块和伽玛模块直接设置在源极 驱动板（SOURCE Board )上， 省去一块控制板（ C/B ), 这样做可以节省制板成 本， 提高竟争力， 同时将伽玛模块做在源极驱动板（SOURCE Board )上可实现 gamma和液晶面板的绑定， 若出现非伽玛模块异常， 需要调整 gamma时， 只需 要更换系统板 ( SOC Board ) 即可， 无需进行 gamma调整， 节省人力成本和时 间； 而单独将伽玛模块设置在元极驱动左板上， 是因为伽玛模块主要用于生成 gamma 电压， 用于数据信号的的校准， 而时序控制模块和电压转换模块则需要 负责栅线和数据线两方面的工作， 将两者分别设置可以使得布线更为方便， 避 免布线复杂使得制作工艺难度升高， 继而增加人力物力成本的情况。
图 5是本发明一种液晶面板实施例四的示意图， 该液晶面板包括负责视频信 号的产生的系统板 1和驱动液晶面板数据线的源极驱动板 2,其中系统板 1包括 系统级芯片 SOC, 所述的系统级芯片 SOC包括设置有存储芯片 FLA的过驱动 模块 OD; 而源极驱动板 2包括源极驱动左板 XL、 耦合于源极驱动左板 XL的 源极驱动右板 XR和设置在源极驱动右板 XR上的时序控制模块 TCON,所述的 系统板 1和源极驱动右板 XR上的时序控制模块 TCON直接电连接； 该液晶面 板还包括电压转换模块 DC/DC和生成用于影像灰阶亮度修正的 gamma电压的 伽玛模块 P-G,其中伽玛模块 P-G设置在源极驱动左板，而电压转换模块 DC/DC 设置在源极驱动右板 XR 。 将时序控制模块、 电压转换模块和伽玛模块都设置 在源极驱动板上， 由于将过驱动模块移到系统级芯片处， 可以比较方便的将封 装面积减小的时序控制模块、 电压转换模块和伽玛模块直接设置在源极驱动板 ( SOURCE Board )上， 省去一块控制板（ C/B ), 这样做可以节省制板成本， 提 高竟争力， 同时将伽玛模块做在源极驱动板（ SOURCE Board )上可实现 gamma 和液晶面板的绑定， 若出现非伽玛模块异常， 需要调整 gamma时， 只需要更换 系统板（SOC Board ) 即可， 无需进行 gamma调整， 节省人力成本和时间； 电 压转换模块的产热相对较多， 且其制板面积比伽玛模块和面积减小后的时序控 制模块来说要大， 将其单独设置在源极驱动左板上， 可以避免电压转换模块产 生的热量对所述的时序控制模块， 以及伽玛模块造成不必要的影响， 改善电压 转换模块 DC/DC的散热情况， 同时使得制板布局更为合理， 方便制板。 以上内 容是结合具体的优选实施方式对本发明所作的进一步详细说明， 不能认定本发 明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通技术人员来 说， 在不脱离本发明构思的前提下， 还可以做出若干筒单推演或替换， 都应当 视为属于本发明的保护范围。
