[0038] 参见图 1和图 2所示， 本申请提供的一种曲面显示面板 400, 包括基板 100, 基板
100包括像素区 110、 集成电路区 130以及位于像素区 110与集成电路区 130之间的 扇出区 120。 其中， 像素区 110包括信号线， 如数据线 111和栅极线 112; 集成电 路区 130包括集成电路驱动器 131 , 集成电路驱动器 131内设有驱动芯片 132以接 收来自软性电路板 200传输的信号； 扇出区 120包括将驱动芯片 132接收到的信号 供应给数据线 111的扇出线 121。 扇出线 121、 数据线 111及栅极线 112的走线参数 跟随所处位置的基板 100的目标曲率的改变而变化。
[0039] 在具体实施例中， 显示面板 400例如为液晶面板， 显示面板包括有基板 100, 在 基板 100上具体的分为像素区 110、 集成电路区 130以及位于像素区 110与集成电 路区 130之间的扇出区 120。 像素区 110包括有信号线， 信号线如数据线 111和栅 极线 112, 集成电路区 130包括集成电路驱动器 131 , 集成电路驱动器 131内设有 驱动芯片 132以接收来自软性电路板 200传输的信号； 扇出区 120包括将驱动芯片 132接收到的信号供应给数据线 111的扇出线 121。 画面显示信号通过软性电路板 200传送到集成电路区 130后， 由集成电路区 130分配到每个集成电路驱动器 131 , 再经过扇出区 121内、 从集成电路驱动器 131放射状连接的扇出线 121将信号发 送至像素区 110内， 由像素区 110内信号线 （如栅极线 112和数据线 111) 分割成 的每个独立的像素的单元来独立响应图像信号， 进而达到显示画面的目的。
[0040] 同吋， 信号线 （如扇出线 121、 数据线 111) 及栅极线 112的走线参数跟随所处 位置的基板 100的目标曲率的改变而变化。
[0041] 具体地， 走线参数包括扇出线 121、 数据线 111及栅极线 112的线宽、 线距、 厚 度及 /或长度， 由于现有的曲面显示面板都是预先制成平面的显示面板再进行弯 曲得来， 在弯曲之前面板内的走线已经设定好， 制程曲面后内部走线因外力作 用容易发生型变， 形成弧度后， 不同于弯曲方向的相邻数据线 111会减小线距， 如果在曲面后需要达到数据线 111的目标线距， 就必须预先在平面吋增加相邻数 据线 111的线距， 同吋数据线 111的线宽也因曲面曲率的不同而需进行预先补偿 , 来达到目标线宽的效果； 栅极线 112—般与面板弯曲的方向平行， 其在面板弯 曲后会受到面板弯曲应力的作用而发生型变， 故在制成曲面之前在原先栅极线 1 12的基础上改变栅极线 112的横截面积来达到抗衡局部应力的效果， 不同的曲率 配以不同的横截面积， 即不同的线宽和线厚； 扇出线 121—端与集成电路驱动器 131相连， 另一端连接至数据线 111 , 数据线 111的走线参数发生改变后， 扇出线 的走线参数也会随之发生改变。
[0042] 进一步地， 数据线 111的走线与基板 100的弯曲方向垂直， 数据线 111的线距和 线宽自基板 100的中部向弯曲的两侧逐渐对称增加。
[0043] 具体地， 数据线 111的走线与基板 100的弯曲方向垂直， 如基板 100为在水平面 内弯曲的曲面显示器， 则数据线 111为一条条垂直于水平面的信号线， 且每根数 据线 111之间相对平行， 并且线距间隔相等。 如果在基板 100处于平面阶段吋， 将数据线 111的线距设成相等的， 那么在基板 100弯曲后， 使用者在基板 100正前 方观看吋， 就会出现随着基板 100两侧曲率的增加， 两侧相邻的数据线 111的线 距会减少。 因为在基板 100弯曲后， 相邻数据线 111的线距在基板 100平面阶段所 处的平面上的投影， 会小于其真实线距投影。 数据线 111的线宽也是随着基板 10 0弯曲后的曲率的增加、 而因基板 100内的应力作用以及倾斜的视角而变小。 因 此， 如果需要达到数据线 111的线距和线宽在曲面的吋候满足预定的目标线距和 线宽， 就需要在基板 100处于平面阶段吋对数据线 111的线距和线宽进行补偿， 即自基板 100的中部向弯曲的两侧逐渐对称增加线距和线宽， 具体增加的尺度由 当前位置基板 100的曲率决定。 （此处适合基板 100的曲率自中间向两侧逐渐对 称增大的情况， 如果基板 100弯曲后的曲率不是均匀向两侧对称增大， 则应当对 应当前基板 100的具体曲率变化来进行补偿）
[0044] 进一步地， 栅极线 112的走线与基板 100的弯曲方向平行， 栅极线 112的线厚和 线宽自基板 100的中部向弯曲的两侧逐渐对称增加。
[0045] 具体地， 栅极线 112的走线与基板 100的弯曲方向平行， 如基板 100为在水平面 内弯曲的曲面显示器， 则栅极线 112为一条条平行于水平面的走线， 且每根栅极 线 112之间相对平行， 线距间隔相等。 在基板 100弯曲后， 栅极线 112会在基板 10 0的弯曲应力下发生型变， 其线宽和线厚会随着应力的增大而减小， 而在基板 10 0上， 曲率越大的位置内部应力对应越大。 因此， 若要栅极线 112的线厚和线宽 达到目标尺寸， 就必须在基板 100处于平面阶段吋， 对栅极线 112的线厚和线宽 进行补偿， 即， 自基板 100的中部向弯曲的两侧逐渐对称增加栅极线 112的线距 和线宽， 让每个位置的栅极线 112的线距和线宽足以抵消掉基板 100的弯曲应力 , 从而在基板 100弯曲后， 栅极线 112的走线参数可以达到目标值 （此处适合基 板 100的曲率自中间向两侧逐渐对称增大的情况， 如果基板 100弯曲后的曲率不 是均匀向两侧对称增大， 则应当对应当前基板 100的具体曲率变化来进行补偿）
[0046] 进一步地， 扇出线 121与数据线 111电性相连， 扇出线 121的线宽、 线距和长度 对应数据线 111的变化而改变。
[0047] 具体地， 因为扇出线 121与数据线 111电性相连， 其走线相互连接， 故扇出线 12 1的线宽、 线距和长度会对应数据线 111的变化而改变。 例如， 上述实施例中， 基板 100的曲率自基板 100的中部向弯曲的两侧逐渐增大， 而数据线 111的线宽和 线距自基板 100的中部向两侧逐渐增加， 则与数据线 111想连接的扇出线 121也需 要对称的增加线宽和线距。 同吋， 因为扇出线 121的线距发生了改变， 所以扇出 线 121的长度也需要随之改变。 扇出线 121的线距增加， 故扇出线 121的长度也随 之增加。 [0048] 参见图 3所示， 具体地， 在弯曲之前的平面基板 100上， 数据线 111自中部向两 侧逐渐增加线距， 线宽也随之增加 （图 3中未示出） ， 弯曲后制成弧形切面的曲 面基板 100a, 此吋， 自人眼 K看向曲面基板 100a所能看到为影像基板 100b, 而影 像基板 100b中数据线 111的走线参数为目标走线参数。 同理， 栅极线 112 (图 3中 未示出） 的厚度在平面基板 100的吋候自基板 100的中部向弯曲的两侧逐渐对称 增加， 已抵消基板 100在弯曲吋自中部向弯曲两侧逐渐增大的内应力， 确保栅极 线 112不发生型变， 扇出线 121 (图 3中未示出） 与数据线 111电性相连， 扇出线 1 21的线宽、 线距和长度对应数据线 111的变化而改变。
[0049] 参见图 4所示。 进一步地， 用于电性连接相邻的驱动芯片 132的驱动线 122呈弓 形弯曲地设于扇出区 120内。
[0050] 具体地， 将驱动线 122设于弓形的设于扇出区 120内可降低相邻两个集成电路 驱动器 131a和 131b之间的走线压力， 走线不光有驱动线 122, 还有其他走线， 增 加集成电路驱动器 131a和 131b之间的走线线距， 避免因走线过于拥挤而容易发 生过热现象， 减少安全隐患。
[0051] 进一步地， 基板 100的厚度自基板 100的中部向弯曲的两侧逐渐对称增加。
[0052] 具体地， 因基板 100在制成曲面后， 自基板 100的中部向弯曲的两侧内应力逐渐 增加， 通过在基板 100内应力大的部位适当的增加基板 100厚度， 从而抵抗基板 1 00弯曲后的内应力， 提高基板 100的性能。
[0053] 参见图 5所示为本申请实施例提供的一种显示装置 500, 包括上述曲面显示面板
400及控制该曲面显示装置的控制单元 （参见图 6所示） 。 参见图 1和图 2所示， 曲面显示面板 400包括基板 100, 基板 100包括像素区 110、 集成电路区 130以及位 于像素区 110与集成电路区 130之间的扇出区 120。 其中， 像素区 110包括数据线 1 11和栅极线 112; 集成电路区 130包括集成电路驱动器 131 , 集成电路驱动器 131 内设有驱动芯片 132以接收来自软性电路板 200传输的信号； 扇出区 120包括将驱 动芯片 132接收到的信号供应给数据线 111的扇出线 121。 扇出线 121、 数据线 111 及栅极线 112的走线参数跟随所处位置的基板 100的目标曲率的改变而变化。
[0054] 在某些实施例中， 曲面显示面板 400可例如为扭曲向列型液晶显示面板， 平面 转换型液晶显示面板或多象限垂直配向型液晶显示面板、 OLED显示面板、 QLE D显示面板。
[0055] 进一步地， 数据线 111的走线与基板 100的弯曲方向垂直， 数据线 111的线距和 线宽自基板 100的中部向弯曲的两侧逐渐对称增加； 栅极线 112的走线与基板 100 的弯曲方向平行， 栅极线 112的厚度自基板 100的中部向弯曲的两侧逐渐对称增 力口； 扇出线 121与数据线 111电性相连， 扇出线 121的线宽、 线距和长度对应数据 线 111的变化而改变。
[0056] 参见图 3所示， 具体地， 在弯曲之前的平面基板 100上， 数据线 111自中部向两 侧逐渐增加线距， 线宽也随之增加 （图 3中未示出） ， 弯曲后制成弧形切面的曲 面基板 100a, 此吋， 自人眼 K看向曲面基板 100a所能看到为影像基板 100b, 而影 像基板 100b中数据线 111的走线参数为目标走线参数。 同理， 栅极线 112 (图 3中 未示出） 的厚度在平面基板 100的吋候自基板 100的中部向弯曲的两侧逐渐对称 增加， 已抵消基板 100在弯曲吋自中部向弯曲两侧逐渐增大的内应力， 确保栅极 线 112不发生型变， 扇出线 121 (图 3中未示出） 与数据线 111电性相连， 扇出线 1 21的线宽、 线距和长度对应数据线 111的变化而改变。
[0057] 参见图 4所示。 进一步地， 用于电性连接相邻的驱动芯片 132的驱动线 122呈弓 形弯曲地设于扇出区 120内。
[0058] 具体地， 将驱动线 122设于弓形的设于扇出区 120内可降低相邻两个集成电路 驱动器 131a和 131b之间的走线压力， 走线不光有驱动线 122, 还有其他走线， 增 加集成电路驱动器 131a和 131b之间的走线线距， 避免因走线过于拥挤而容易发 生过热现象， 减少安全隐患。
[0059] 进一步地， 基板 100的厚度自基板 100的中部向弯曲的两侧逐渐对称增加。
[0060] 具体地， 因基板 100在制成曲面后， 自基板 100的中部向弯曲的两侧内应力逐渐 增加， 通过在基板 100内应力大的部位适当的增加基板 100厚度， 从而抵抗基板 1 00弯曲后的内应力， 提高基板 100的性能。
[0061] 参见图 6所示， 为本申请实施例提供的一种显示装置的控制单元模块图， 控制 单元包括吋序控制电路模块、 灰阶电压发生电路模块、 DC-DC转换电路模块、 显示屏源极驱动电路模块以及显示屏栅极驱动模块。 前端视频信号处理电路送 来的 LVDS (ί氐压差分信号技术接口） 格式的图像信号， 经由吋序控制电路模块 转换为显示屏周边源极驱动和栅极驱动集成电路所需的 RSDS (ί氐摆幅差分信号 ) 格式的图像信号， 同吋由吋序控制电路模块输出源极驱动、 栅极驱动电路工 作必须的驱动控制信号 （栅极驱动电路移位寄存器 "位移 "脉冲信号 STV、 栅极 驱动电路移位寄存器 "触发 "脉冲信号 CKV、 源极驱动电路移位寄存器"位移"起 始脉冲信号 STH、 源极驱动电路移位寄存器"触发"脉冲信号 CKH、 源极像素信 号极性逐行反正控制信号 POL ) , 这些信号都加到显示屏周边的驱动电路上， 最终完成图像在显示屏上的显示。
[0062] 液晶屏逻辑驱动电路是一个独立系统， 这部分电路工作需要各种电源供电， 如 VDD (数字电源） 供电、 栅极驱动供电 VGH (正电源输入脚） 和 VGL (负电源 输入脚） 、 伽马基准电压 VGA (视频图形阵列） 等。 为了保证该系统的稳定工 作， 专门设置一个幵关电源电路， 该电路把送来的 5V/12V电压， 经过 DC-DC转 换电路转换， 产生逻辑驱动电路所需的 VDD、 VGA. VGH、 VGL等电压。
