Description

显示面板的检测装置 技术领域
本发明涉及面板检测领域,特别是涉及一种显示面板的检测装置。
背景技术
随着科技的发展,人们对显示面板的显示要求越来越高。现有的显示面板具有RGB显示面板以及RGBW显示面板,其中RGB显示面板中包括红色像素单元、绿色像素单元以及蓝色像素单元;RGBW显示面板包括红色像素单元、绿色像素单元、蓝色像素单元以及白色像素单元。
在显示面板出厂之前,会对面板进行点亮测试,一般会检测面板的纯白画面、纯红画面、纯绿画面以及纯蓝画面。请参照图1,图1为现有的RGB显示面板的检测装置的结构示意图。其中R为红色信号源,G为绿色信号源,B为蓝色信号源,红色信号源R通过红色短路棒(shorting bar)和RGB显示面板中的所有红色像素单元连接,绿色信号源G通过绿色短路棒和RGB显示面板中的所有绿色像素连接,蓝色信号源B通过蓝色短路棒和RGB显示面板中的所有蓝色像素连接。
请参照图2,图2为现有的RGBW显示面板的检测装置的结构示意图。其中R为红色信号源,G为绿色信号源,B为蓝色信号源,W为白色信号源,红色信号源R通过红色短路棒和RGB显示面板中的所有红色像素单元连接,绿色信号源G通过绿色短路棒和RGB显示面板中的所有绿色像素连接,蓝色信号源B通过蓝色短路棒和RGB显示面板中的所有蓝色像素连接,白色信号源W通过白色短路棒和RGB显示面板中的所有白色像素单元连接。
但是现有的显示面板制作厂家一般会使用同一套检测装置对RGB显示面板以及RGBW显示面板进行检测,如使用RGB显示面板的检测装置检测RGBW显示面板时,如图3所示,图3为使用现有的RGB显示面板的检测装置检测RGBW显示面板时的使用示意图,由于RGB显示面板的检测装置具有三个短路棒,RGBW显示面板却具有四种像素单元。因此检测装置只能检测RGBW显示面板的全亮画面,无法检测单独的红色画面、绿色画面以及蓝色画面。
如使用RGBW显示面板的检测装置检测RGB显示面板时,如图4所示,图4为使用现有的RGBW显示面板的检测装置检测RGB显示面板时的使用示意图,由于RGBW显示面板的检测装置具有四个短路棒,RGB显示面板只具有三种像素单元。因此检测装置也只能检测RGB显示面板的全亮画面,无法检测单独的红色画面、绿色画面以及蓝色画面。

在图中,结构相似的单元是以相同标号表示。
请参照图5,图5为本发明的显示面板的检测装置的优选实施例的结构示意图。该显示面板的检测装置50包括十二个信号源输入端口51以及十二个短路棒52,信号源输入端口51用于输入检测信号,短路棒52与信号源输入端口51一一对应,短路棒52的一端与对应的信号源输入端口51连接,短路棒52的另一端与显示面板53的相应的数据线连接。
如图5所述,第n个短路棒52与显示面板53的第n+12m条数据线(即每行的第n+12m个像素单元531)连接,其中n为小于等于十二的正整数,m为非负整数。即第一个短路棒52分别与显示面板53的1、13、25……1+12m条数据线连接,第二个短路棒52分别与显示面板53的2、14、126……2+12m条数据线连接,……第n个短路棒52分别与显示面板53的n、n+12、n+24……n+12m条数据线连接。即短路棒52以12为周期与显示面板53的数据线连接。
请参照图6,图6为使用本发明的显示面板的检测装置检测RGB显示面板时的使用示意图。本优选实施例的显示面板的检测装置用于检测RGB显示面板61时,RGB显示面板61包括红色像素(第一像素)、绿色像素(第二像素)以及蓝色像素(第三像素)。
当检测该RGB显示面板61的全亮画面时,所有的信号源输入端口51均通过短路棒52向RGB显示面板61的所有像素输入检测信号,这样相邻的红色像素、绿色像素以及蓝色像素合成全亮画面,完成RGB显示面61板的全亮画面的检测。
当检测该RGB显示面板61的全红画面时,第1、4、7、10个信号源输入端口51输入检测信号,其他信号源输入端口51不输入检测信号,第1、4、7、10个信号源输入端口51对应的短路棒52连接的像素单元均为红色像素单元,因此RGB显示面板61的所有红色像素单元被点亮,完成RGB显示面板61的纯红画面的检测。
当检测该RGB显示面板61的全绿画面时,第2、5、8、11个信号源输入端口51输入检测信号,其他信号源输入端口51不输入检测信号,第2、5、8、10个信号源输入端口51对应的短路棒52连接的像素单元均为绿色像素单元,因此RGB显示面板61的所有绿色像素单元被点亮,完成RGB显示面板61的纯绿画面的检测。
当检测该RGB显示面板61的全蓝画面时,第3、6、9、12个信号源输入端口51输入检测信号,其他信号源输入端口51不输入检测信号,第3、6、9、12个信号源输入端口51对应的短路棒52连接的像素单元均为蓝色像素单元,因此RGB显示面板61的所有蓝色像素单元被点亮,完成RGB显示面板61的纯蓝画面的检测。
这样即完成了本优选实施例的显示面板的检测装置50对RGB显示面板61的画面检测过程。
请参照图7,图7为使用本发明的显示面板的检测装置检测RGBW显示面板时的使用示意图。本优选实施例的显示面板的检测装置用于检测RGBW显示面板71时,RGBW显示面板71包括红色像素(第一像素)、绿色像素(第二像素)、蓝色像素(第三像素)以及白色像素(第四像素)。
当检测该RGBW显示面板71的全亮画面时,所有的信号源输入端口51均通过短路棒52向RGBW显示面板71的所有像素输入检测信号,这样相邻的红色像素、绿色像素、蓝色像素以及白色像素合成全亮画面,完成RGBW显示面板71的全亮画面的检测。
当检测该RGBW显示面板71的全红画面时,第1、5、9个信号源输入端口51输入检测信号,其他信号源输入端口51不输入检测信号,第1、5、9个信号源输入端口51对应的短路棒52连接的像素单元均为红色像素单元,因此RGBW显示面板71的所有红色像素单元被点亮,完成RGBW显示面板71的纯红画面的检测。
当检测该RGBW显示面板71的全绿画面时,第2、6、10个信号源输入端口51输入检测信号,其他信号源输入端口51不输入检测信号,第2、6、10个信号源输入端口51对应的短路棒52连接的像素单元均为绿色像素单元,因此RGBW显示面板71的所有绿色像素单元被点亮,完成RGBW显示面板71的纯绿画面的检测。
当检测该RGBW显示面板71的全蓝画面时,第3、7、11个信号源输入端口51输入检测信号,其他信号源输入端口51不输入检测信号,第3、7、11个信号源输入端口51对应的短路棒52连接的像素单元均为蓝色像素单元,因此RGBW显示面板71的所有蓝色像素单元被点亮,完成RGBW显示面板71的纯蓝画面的检测。
当检测该RGBW显示面板71的全白画面时,第4、8、12个信号源输入端口51输入检测信号,其他信号源输入端口51不输入检测信号,第4、8、12个信号源输入端口51对应的短路棒52连接的像素单元均为白色像素单元,因此RGBW显示面板71的所有白色像素单元被点亮,完成RGBW显示面板71的纯白画面的检测。
这样即完成了本优选实施例的显示面板的检测装置50对RGBW显示面板71的画面检测过程。
本发明的显示面板的检测装置通过设置十二个信号源输入端口以及十二个短路棒,实现了对RGBW显示面板和RGB显示面板均可以进行各色画面的纯色检测;解决了现有的显示面板的检测装置不能对RGBW显示面板进行纯色检测或不能对RGB显示面板进行纯色检测的技术问题。
综上所述,虽然本发明已以优选实施例揭露如上,但上述优选实施例并非用以限制本发明,本领域的普通技术人员,在不脱离本发明的精神和范围内,均可作各种更动与润饰,因此本发明的保护范围以权利要求界定的范围为准。
