Solution can adjust photometric measurer in panel assembly in order to enable the light intensity that illumination region 20 emits does not influence the testing result of photometric measurer 30
The distance between 30 and illumination region so that the distance is more than some threshold value, to make illumination region 20 be scattered by light penetrating panel 10
The arrival light intensity If*f (x, sE) of the first part opposite to photometric measurer 30 is far smaller than external environment light intensity and passes through light penetrating panel
10 reach light intensity Iw*f (dD, sE) the * f (dE, sE), i.e. If*f (x, sE) of photometric measurer 30<<Iw*f (dD, sE) * f (dE, sE),
It enables
If*f (x, sE)=k*Iw*f (dD, sE) * f (dE, sE), k<<1(4)
Wherein, in an embodiment of the present invention, it is required according to measurement accuracy, can use k is 0.1 or 0.01.It later, can basis
Above-mentioned formula (4) is derived, and x values are obtained, it is possible to understand that when the minimum x values of the distance between photometric measurer 30 and illumination region 20
When, light that illumination region 20 emits does not interfere with the measurement of photometric measurer 30 therefore can be using the x values as the first spacing X1.
Optionally, in one embodiment of the invention, it can be formed in the other parts of above-mentioned light penetrating panel 10 predetermined
Pattern.Wherein, in an embodiment of the present invention, scheduled pattern can be the coloured pattern of tool, can also be no face
The transparent pattern of color, such as have coloured peony, Little Bear, rabbit etc..The beauty of panel is improved as a result,.
Preferably, to make display luminous component (illumination region 20 i.e. in the embodiment of the present invention) in air conditioner penetrate light transmission
Panel 10 is shown clearly, improves user satisfaction and double face slab structure may be used in one embodiment of the invention, interior
Layer is using the material of low astigmatism rate, and outer layer uses the material of high astigmatism rate, so that the position that can be shone concentrates in air conditioner
Display unit.Specifically, according to one embodiment of present invention, as shown in figure 3, light penetrating panel 10 may include the first photic zone 13
With the second photic zone 14.Wherein, in an embodiment of the present invention, as shown in figure 3, illumination region 20 and photometric measurer 30 may be provided at
The side of one photic zone 13, the second photic zone 14 may be provided on the other side of the first photic zone 13, wherein the second photic zone 14
Astigmatism rate be more than the first photic zone 13 astigmatism rate.That is, it is the interior of light penetrating panel 10 that the first photic zone 13, which is appreciated that,
Layer, the second photic zone 14 be appreciated that be light penetrating panel 10 outer layer.
It should be appreciated that due to the inner layer material using low astigmatism rate, will cause the light of illumination region 20 from internal layer panel (i.e.
First photic zone 13) middle propagate could relatively decay at a distance, if photometric measurer 30 can receive this light source apart from relatively closely, to shadow
The accuracy of the measurement of external environment light intensity is rung, therefore to increase the distance between illumination region 20 and photometric measurer 30 L2 so that If*
f(x,sC)<<Iw*f (dB, sB) * f (dC, sC), i.e.,：
If*f (x, sC)=k*Iw*f (dB, sB) * f (dC, sC), k<<1(5)
Wherein, the k in above-mentioned formula (5) is coefficient and 0<k<1, Iw is external environment light intensity, and dB is the second photic zone 14
Thickness, sB are the astigmatism rate of the second photic zone 14, and dC is the thickness of the first photic zone 13, and sC is the astigmatism of the first photic zone 13
Rate.
In addition, in an embodiment of the present invention, being required according to measurement accuracy, can use k is 0.1 or 0.01.According to above-mentioned formula
(5), preset second spacing X2 can be obtained：
X2=-ln (k* (Iw* (e^ (- dB*sB)) * (e^ (- dC*sC)))/If)/sC (6)
Wherein k is coefficient and 0<k<1, Iw is external light intensity, and dB is the thickness of the second photic zone 14, and sB is the second photic zone

Light intensity.
In this way according to this second spacing X2, if actual range L2 between photometric measurer 30 and illumination region 20 be more than this second
Spacing X2 then can guarantee that photometric measurer 30 is surveyed light precision and do not influenced by the light that illumination region 20 is sent out.
The material of low astigmatism rate can be used by using double face slab structure, internal layer as a result, outer layer is using high astigmatism rate
Material, so that the position that can be shone concentrates on the display unit in air conditioner so that the display luminous component in air conditioner penetrates
Display panel is clear, to improve user satisfaction.
Wherein, according to one embodiment of present invention, illumination region 20 scatters to photometric measurer 30 relatively by light penetrating panel 10
First part arrival light intensity can pass through following formula calculate obtain：
In=If*f (x, sA) (7)
Wherein In is above-mentioned arrival light intensity, and If is the transmitting light intensity of illumination region 20, and f (x, sA) is with apart from exponentially
