Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0029] The present application provides a panel, including a substrate, a signal line disposed on the substrate, and a plurality of light emitting components. Multiple light emitting components are distributed along the first direction. Each light-emitting component is connected with a signal line. The signal line includes at least two signal input terminals. Signals are applied to the signal lines via at least two signal inputs. This application loads the signal on the signal line through m...

Abstract

The embodiment of the invention discloses a driving circuit, a display panel and a panel. The driving circuit comprises a substrate, a signal line and a plurality of load assemblies, the signal line and the load assemblies are arranged on the substrate, the load assemblies are distributed along a first direction, and each load assembly is connected with the signal line; the signal line comprises at least two signal input ends, and signals are loaded to the signal line through the at least two signal input ends. Signals are loaded on the signal line through the multiple signal input ends, the consistency of the overall voltage on the signal line is improved, and therefore the problem that the driving voltage of a load far away from the signal input ends is insufficient is solved; meanwhile, the voltage value actually loaded on a related device can be reduced to avoid damage to a load element close to the signal input ends, and the power loss on the signal line is reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a driving circuit, a display panel and the panel. Background technique [0002] For miniLED and MicroLED panels that use a glass substrate as a carrier, the thickness of the metal layer deposited on the glass substrate is limited, and it is difficult to reach the thickness level of the metal layer on the conventional PCB substrate. In large-size LED panels, the impedance values ​​of key signal lines with large spans such as ground signal lines, chip drive signal lines, and LED drive signal lines will be large, causing obvious line loss (IR Drop). [0003] The signal lines of the existing large-size LED panels are only provided with one signal input terminal. In order to ensure that the LED at the farthest end away from the signal input terminal can obtain a normal working voltage, the voltage signal loaded on the signal input terminal needs to take into account the fac...
