Film transistor array structure

Abstract

A film transistor array structure comprises a first display zone, a first fan-out zone, and a second fan-out zone; at least a data line and at least a scan line mutually vertically extend in the display zone; the first fan-out zone comprises a first N channel metal oxidation semiconductor switch and a first measurement pad; the second fan-out zone comprises a second N channel metal oxidation semiconductor switch and a second measurement pad; a first measurement linear system extends between the display zone and the first fan-out zone; the first N channel metal oxidation semiconductor switch connects the end of the data line with the first measurement pad; a second measurement linear system extends between the display zone and the second fan-out zone; the second N channel metal oxidation semiconductor switch connects the end of the scan line with the second measurement pad. When the first and second N channel metal oxidation semiconductor switches are connected, voltage signal intensity of the signal line and scan line after linear attenuation can be directly obtained by measuring the first and second measurement pads.

Description

technical field [0001] This case relates to a display panel, especially a thin film transistor array (Thin Film Transistor (TFT) Array) structure for liquid crystal displays, the output signals of the scanning lines and data lines can be directly measured. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD, ThinFilmTransistorLiquidCrystalDisplay) is one of the main products of the current flat panel display, and has become an important display platform for information products and video products. [0003] refer to figure 1 , the main driving principle of the thin film transistor liquid crystal display 40 is that the system main board (not shown) transmits the compressed signal of red / green / blue (R / G / B), the control signal and the electric power through the flat cable (not shown) and the printed circuit board 50 The connector 52 is connected. The circuit board 50 is connected to a TFT array (Array) 57 through a Source-ChiponFilm (S-COF) 54 an...

Problems solved by technology

However, in practical applications, because the ends of the data lines and scanning lines are located at the edge of the glass substrate, the measurement can only be performed after the glass substrate is subjected to crack drilling.

This method takes a long time, and the product is destroyed after the lobes are drilled, resulting in waste

At the same time, after the lobes are drilled, the liquid crystal will volatilize, and the human body will have adverse effects on health after inhalation.
