To explain.
The inventors of the present application found that solving at comprehensive screen mobile phone infrared sensor position that light transmittance is lower to ask at present
Topic, the method for use is that the different zones on display screen viewing area design different pixel densities, as shown in Figure 1, i.e. infrared
It is low pixel density above screen where sensor 13, the low pixel density region 11 in corresponding diagram, display screen main body is high picture
Plain density, the high pixel density area 12 in corresponding diagram.In low pixel density region 11, since pixel density is low, mask plate aperture is few,
Spacing is big, and the material that low pixel density region 11 is deposited is few, helps to improve light transmittance.Low pixel density region 11 is also required to such as high picture
Plain density region 12 equally normally shows the functions such as time, electricity, signal strength.
The inventors of the present application found that realizing that the method that different zones design different pixel densities is using two at present
Low pixel density region 11 and high pixel density area 12 is separately deposited in mask plate, by taking cathode evaporation as an example, as shown in Fig. 2, first using
The cathode material of layer is deposited in low pixel density region 11 for first mask plate (mask plate is completely open mask plate),
High pixel density area 12 is blocked while vapor deposition and is not deposited, after the completion of to be deposited, then changes second mask plate (mask plate
For completely open mask plate) in the cathode material of the one floor normal thickness of vapor deposition of high pixel density area 12, as shown in figure 3, being deposited
While low pixel density region 11 blocked be not deposited, the evaporation material of such low pixel density region 11 is relatively thin, and light transmittance is higher.
The inventors of the present application found that being an evaporation source as used in cathode, shade (shadow) phenomenon is more tight
Weight is easy biggish shadow occur in low pixel density region 11 and 12 bonding pad of high pixel density area, such as: high pixel density area
12 shadow can cover the pixel of a few row low pixel density regions 11, and the shadow of low pixel density region 11 can cover a few row height pictures
The pixel of plain density region 12 causes low pixel density region 11 and 12 film thickness of high pixel density area abnormal, to cause to show bad.
In addition, the inventors of the present application found that camera 14 can not be blocked using the method that two mask plates are separately deposited
Region, and the requirement of two mask plates contraposition is higher, will increase cost, can also extend the process time of vapor deposition, reduces production capacity.
