A display module and terminal

Abstract

A display module and terminal, including: two or more box test CT units and source switches; wherein, the CT unit is arranged in the notch (Notch) area of ​​the concave groove, used for: outputting the CT test Test signal; source switch is used to: turn on or off each source trace for CT test to transmit test signal from CT unit. The embodiment of the present invention avoids the dark line risk caused by electrostatic discharge (ESD) and circuit corrosion, and improves the dark line defect caused by damage to the CT unit caused by ESD.

Description

technical field [0001] This article involves but is not limited to display technology, especially a display module and terminal. Background technique [0002] With the advent of the era of full screens, the display designs of "bangs" and "water drop corners" have been applied to mainstream electronic devices. Since the opposite side of the integrated circuit (IC) is designed with a concave groove (also known as a U-shaped groove, which is a structure such as a letter U), the position of the concave groove involves capacitance compensation (Source (Source) wiring and gate (Gate) routing crossing, improving the poor diagonal band (Mura) in the notch (Notch) area) and Gate connectivity on the left and right sides; referring to the relevant design, there is not enough space to arrange the box test (CT, CellTest) units, so , the current main display screen with concave grooves, CT units are designed on the opposite side of the integrated circuit (IC), that is, the single-layer a...

Since the opposite side of the integrated circuit (IC) is designed with a concave groove (also known as a U-shaped groove, which is a structure such as a letter U), the position of the concave groove involves capacitance compensation (Source (Source) wiring and gate (Gate) routing crossing, improving the poor diagonal band (Mura) in the notch (Notch) area) and Gate connectivity on the left and right sides; referring to the relevant design, there is not enough space to arrange the box test (CT, CellTest) units, so , the current main display screen with concave grooves, CT units are designed on the opposite side of the integrated circuit (IC), that is, the single-layer area of ​​the box (Cell); figure 1 It is a schematic diagram showing the composition of modules in related technologies, such as figure 1 As shown, the CT unit is connected with the box test positive drive (CTD-ODD), the box test negative drive (CTD-EVEN) and the box test switch (CTSW); during the sample preparation process of the display module, including the color film (CF) surface Processes such as cutting (along the CF boundary) and wiping and cleaning of single-layer areas all have the risk of electrostatic discharge (ESD) damaging the CT unit, causing dark line defects on the display screen
