The second Light-emitting diode LED 2 in two sub-pixel SP2.Therefore, compared to only needing to output current to the first Light-emitting diode LED 1
Pixel drive elements transistor for, by the shared pixel of the first Light-emitting diode LED 1 and the second Light-emitting diode LED 2
The transistor of driving element may need to export bigger electric current.Therefore, by the first Light-emitting diode LED 1 and second luminous two
The channel width/length of pole pipe LED2 shared transistor only outputs current to the crystalline substance of the first Light-emitting diode LED 1 than that can be greater than
The channel width/length ratio of body pipe.In addition, output current to more multiple optical diode (including the first Light-emitting diode LED 1 with
Second Light-emitting diode LED 2) transistor can have bigger channel width/length ratio.On the other hand, for exporting electric current
To identical quantity light emitting diode (including the first Light-emitting diode LED 1 and the second Light-emitting diode LED 2) transistor and
Speech, the channel width/length ratio for outputing current to the transistor of red light-emitting diode, which can be greater than, outputs current to green luminescence
The channel width/length ratio of the transistor of diode, and output current to the channel width of the transistor of green light LED/
Length outputs current to the channel width/length ratio of the transistor of blue light-emitting diode than that can be greater than.For example, feux rouges is sent out
Optical diode refers to that dominant wavelength ranges are the light emitting diode of 610nm to 670nm.Green light LED refers to that dominant wavelength ranges are
The light emitting diode of 510nm to 560nm.Blue light-emitting diode refers to that dominant wavelength ranges are the light-emitting diodes of 254nm to 470nm
Pipe.
In some embodiments, the second light emitting diode can be adjusted by adjusting the resistance value of the first connection electrode W1
The brightness of LED2.For example, the method for adjusting the first connection electrode W1 includes the length for adjusting the first connection electrode W1, width
Degree, material, thickness, shape or combinations thereof.In some embodiments, the second sub-pixel SP2 have biggish area when, need compared with
Second Light-emitting diode LED 2 of high brightness.In this way, the resistance value of the first connection electrode W1 can be reduced, to improve the second hair
The driving current of optical diode LED2.On the other hand, the second Light-emitting diode LED 2 in the second sub-pixel SP has lower
When luminous efficiency (compared to the second Light-emitting diode LED 2 of the second adjacent sub-pixel SP2), need to improve this second shine
The input current of diode (LED) 2, therefore the resistance value of the first connection electrode W1 can be reduced.It in some embodiments, can raising portion
The resistance value of point the first connection electrode W1 so that picture show it is more continuous with it is uniform.It can be according to the face of the second sub-pixel SP2
Product, the quantity of the second sub-pixel SP2 the second Light-emitting diode LED 2 for being included, second in the second sub-pixel SP2 shine two
The luminous efficiency of pole pipe LED2 or other design requirements adjust the resistance value of the first connection electrode W1, and the present invention is not with first
The above-mentioned characteristic (e.g. length, width, material, thickness, shape or combinations thereof) of connection electrode W1 is limited.
In the embodiment shown in Figure 1B, multiple first Light-emitting diode LED 1 of same a line that D2 is arranged in a second direction
With the dominant wavelength ranges having the same of the second Light-emitting diode LED 2.In these embodiments, in a line neighbouring
