The invention relates to a display circuit, a display device and display equipment. The display circuit comprises a current limiting unit, a first electrode driving control end, a plurality of secondelectrode driving control ends and a plurality of display units, the first electrode driving control end is an anode driving control end / cathode driving control end, and the second electrode driving control ends are a cathode driving control end / anode driving control end; one end of each display unit is connected with the first electrode driving control end through the current limiting unit, and the other end of each display unit is connected with the corresponding second electrode driving control end. By adopting the display panel, the display reliability can be ensured, and the use number ofthe current limiting units is reduced, so that the layout space is effectively reduced, and the circuit layout pressure is reduced.
Description
technical field [0001] The present application relates to the field of electronic technology, in particular to a display circuit, a display device and a display device. Background technique [0002] In a display device, a structure in which multiple branches of display electronic components are connected in parallel is commonly used, for example, multiple LEDs (Light Emitting Diodes) are connected in parallel. In order to ensure normal display when one of the display electronic components in the parallel branch is damaged, a current limiting resistor is generally configured for each branch. In this case, when the number of branch circuits is relatively large, a large number of current limiting resistors will be required, occupying board layout space and increasing the pressure of circuit layout. Contents of the invention [0003] Based on this, it is necessary to provide a display circuit, a display device, and a display device that enhance display reliability and reduce ...
