Display panel

A display panel, comprising a first driving thin-film transistor, a second driving thin-film transistor, a first organic light-emitting diode (OLED) device, and a second organic light-emitting diode (OLED) device, wherein the first driving thin-film transistor is electrically connected to the first OLED device, the second driving thin-film transistor is electrically connected to the second OLED device, and the first OLED device and the second OLED device emit light of different colors;

• the first driving thin-film transistor comprises a first active layer, and a channel portion of the first active layer has a first aspect ratio;
• the second driving thin-film transistor comprises a second active layer, and a channel portion of the second active layer has a second aspect ratio;
• a width of the channel portion of the first active layer ranges between 1.5 microns and 4 microns, and a length of the channel portion of the first active layer ranges between 15 microns and 50 microns;
• the first OLED device is a green OLED device, and the second OLED device is a first non-green OLED device;
• and
• the first aspect ratio of the first driving thin-film transistor electrically connected to the green OLED device is smaller than the second aspect ratio of the second driving thin-film transistor electrically connected to the first non-green OLED device;
• wherein the display panel further comprises a third driving thin-film transistor and a second non-green OLED device, the second non-green OLED device and the first non-green OLED device emit light of different colors, respectively, and the third driving thin-film transistor is electrically connected to the second non-green OLED device;
• the third driving thin-film transistor comprises a third active layer, and a channel portion of the third active layer has a third aspect ratio;
• and
• the first aspect ratio is smaller than the third aspect ratio;
• wherein the first non-green OLED device is one of a red OLED device and a blue OLED device, and the second non-green OLED device is another one of a red OLED device and a blue OLED device;
• and
• wherein the second aspect ratio is equal to the third aspect ratio.
