Description

显示器电路Display circuit

技术领域technical field

本发明有关于于一种测试垫(pad)电路，特别是有关于一种显示器电路，其将测试垫设置在玻璃基板或系统电路板上。The present invention relates to a test pad circuit, in particular to a display circuit, wherein the test pad is arranged on a glass substrate or a system circuit board.

背景技术Background technique

一般而言，液晶显示器包括显示面板、多个驱动器、及系统电路板。其中，显示面板由玻璃基板所形成。多个驱动器又包括扫描驱动器及数据驱动器，用以控制显示面板的显示单元。依据驱动器与显示面板接合方式的不同，可分为晶粒软磨接合(Chip-On-Film，COF)及晶粒玻璃接合等封装技术。其中，COF接合是一种将晶粒接合在软性电路板(Flexible Printed CircuitBoard，FPC)上的技术。也就是将驱动器直接安放在FPC的薄膜(Film)上，且FPC在电连接于显示面板及系统电路板之间。COG接合是一种将晶粒直接连接玻璃面板上的技术。也就是将驱动器直接连接显示面板。Generally speaking, a liquid crystal display includes a display panel, a plurality of drivers, and a system circuit board. Wherein, the display panel is formed by a glass substrate. The multiple drivers include a scan driver and a data driver for controlling the display unit of the display panel. Depending on the bonding method between the driver and the display panel, it can be divided into packaging technologies such as Chip-On-Film (COF) and chip glass bonding. Among them, COF bonding is a technology for bonding dies to a flexible printed circuit board (Flexible Printed Circuit Board, FPC). That is, the driver is directly placed on the film of the FPC, and the FPC is electrically connected between the display panel and the system circuit board. COG bonding is a technology that directly attaches dies to glass panels. That is, connect the driver directly to the display panel.

驱动器具有多个信号输出端口，且通常第一及最后端口是作为测试端口。当以COF作为驱动器与显示面板间的接合方式时，一般会于薄膜表面留下测试端口的测试垫，且此测试垫是配置在FPC的下方。因此，欲执行驱动器的测试操作时，必须将FPC翻面，延长了测试时间。当以COG作为驱动器与显示面板间的接合方式时，在玻璃基板上不会留在测试端口的测试垫。且由于驱动器直接镶嵌在玻璃基板，当欲执行驱动器的测试操作时，只能以探针测量系统(probe station)来测量驱动器的输出波形。此会造成玻璃基板上的线路刮坏损伤，且需花费较多分析时间。The driver has multiple signal output ports, and usually the first and last ports are used as test ports. When COF is used as the bonding method between the driver and the display panel, generally a test pad for a test port is left on the surface of the film, and the test pad is arranged under the FPC. Therefore, when the test operation of the driver is to be performed, the FPC must be turned over, which prolongs the test time. When COG is used as the bonding method between the driver and the display panel, there will be no test pads left on the test port on the glass substrate. And because the driver is directly embedded in the glass substrate, when the test operation of the driver is to be performed, the output waveform of the driver can only be measured with a probe station. This will cause scratch damage to the circuit on the glass substrate, and it will take a lot of analysis time.
