Abstract

The invention discloses an impedance value detection method for a display and a display carrying structure, which is applied to quality surveillance of display modules subsequent to chip packaging. The display comprises a display panel, a carrying region and a carrying structure, wherein the carrying structure thereof comprises: a first connection lead and a second connection lead, which are arranged inside the carrying structure and respectively comprise a first projection pressing region and a second projection pressing region; and the carrying structure also comprises: a first extension lead and a second extension lead, which are arranged on the surface of the display panel outside the carrying region and are respectively electrically connected with the first connection lead and the second connection lead. The method achieves, in the process of production, the purpose of implementing simple detection and estimation on continuity, reliability and stability in transmitting signal in the carrying region of the display panel.

Description

【Technical field】 [0001] The present invention relates to a display and a method for detecting the impedance value of the display mounting structure, in particular to a display that can be applied to a display module for simple detection and evaluation of the continuity, reliability and stability of signal transmission in the display panel mounting area It is equipped with a display structure. 【Background technique】 [0002] As the peripheral driver chips and drive circuit devices of the display panel of the flat panel display module become more complex, the flat panel display module needs to use the chip mounting area on the surface of the display panel to bond the driver chip, printed circuit board and other components to transmit control signals. However, taking the liquid crystal display module as an example, the prior art liquid crystal display module construction technology includes electronic construction types such as tape and reel automatic bonding packaging technol...
