Abstract

The invention provides a display motherboard, a display panel and a preparation method for the display panel, wherein the display motherboard includes multiple rows of display units, the first side edge of the display panel is provided with the first row of display units, and the second side edge of the display panel A second row of display units is provided; from the second side to the first side of the first row of display units, the electrode-facing area of ​​the storage capacitor of the first row of display units gradually increases; from the first side of the second row of display units To the second side, the area facing the electrodes of the storage capacitors of the second row of display units gradually increases. According to the invention, the storage capacitor is progressively compensated for the low-gray-scale brightness unevenness caused by the uneven manufacturing process, and the size of the storage capacitor is adjusted according to the variation of the manufacturing process to ensure that the current flowing through each light-emitting diode in the display panel is basically the same, thereby improving the performance of the display panel. Brightness uniformity at low gray levels.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display motherboard, a display panel and a method for preparing the display panel. Background technique [0002] AMOLED (Active-matrix organic light emitting diode, active matrix organic light-emitting diode) is a current-driven device. When a driving current flows through the organic light-emitting diode, the organic light-emitting diode emits light. The driving current is generally provided by the AMOLED pixel drive circuit, and the pixel drive The circuit generally includes at least one driving TFT (ThinFilm Transistor, thin film transistor), switching TFT and storage capacitor. When the switching TFT is turned on, the data signal is transmitted to the gate of the driving TFT and stored in the storage capacitor. The driving TFT generates a driving current to Drive organic light-emitting diodes to emit light. [0003] At present, AMOLED mobile phone products often have the ...
