Abstract

The invention provides a display panel and electronic equipment. The display panel comprises a substrate, a thin film transistor layer and a light-emitting structure, wherein the thin film transistorlayer comprises a plurality of thin film transistors, each thin film transistor comprises a first metal layer, a second metal layer, a buffer layer, an active region, a gate dielectric layer, a gate metal layer, an interlayer dielectric layer, a source region metal layer, a drain region metal layer and a planarization layer, the active region comprises a channel region, a source region and a drainregion, the source region and the drain region are arranged at two sides of the channel region, the source region metal layer is arranged on the interlayer dielectric layer and is electrically connected with the source region and the first metal layer via a through hole, and the drain region metal layer is arranged on the interlayer dielectric layer and is electrically connected with the drain region and the second metal layer via a through hole. With the display panel and the electronic equipment, provided by the invention, the resistance of a signal line in the display panel can be effectively reduced.

Description

technical field [0001] The invention relates to the field of electronic display, in particular to a display panel and electronic equipment. Background technique [0002] In order to reduce the impact of capacitive coupling on system impedance, the thin film transistor layer of the display panel usually adopts top-gate thin film transistors to reduce the load of signal lines. But for a large-size or super-size display, the resistance of the signal line becomes unnegligible. This resistor drains the supply voltage, resulting in uneven brightness of the display panel. [0003] Therefore, it is necessary to propose a thin film transistor structure capable of eliminating the voltage drop of the signal line. Contents of the invention [0004] The invention provides a display panel and electronic equipment, which can effectively reduce the resistance of signal lines in the display panel. [0005] In order to solve the above problems, the present invention provides a display pa...
