Abstract

The invention discloses a TFT array substrate and an OLED panel. The TFT array substrate includes a display area and a non-display area. The non-display area is provided with a gate line connected toa control chip. The TFT array substrate includes a flexible substrate. The flexible substrate includes a metal line change sublayer in the non-display area and close to the display area; and a thin film transistor layer disposed on the flexible substrate and including a plurality of thin film transistors corresponding to the display area, wherein the gate line of each of the thin film transistor layers and the gate line of the non-display area are changed through the metal line change sublayer.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a TFT array substrate and an OLED panel. Background technique [0002] Organic light emitting diode (OLED) has many excellent characteristics such as self-illumination, low energy consumption, wide viewing angle, rich colors, fast response, and flexible screens can be prepared. The related design has become a development trend in the field of display technology. Among them, reducing the width of the non-display area at the edge of the OLED panel is one of the main issues. [0003] In the current common OLED panel design, such as figure 1 As shown, the scanning lines, data lines and grounding lines of the TFT array in the display area 2 are respectively connected to the Chip on film area (chip on film, COF). Since the gate wiring is located on the gate metal layer, and the VDD wiring 4 and the VSS wiring 5 are located in the source-drain layer, therefore, the gate wiring 3 wil...
