The scattering unit 11 of nephelometric turbidity unit reduces the self luminous influence on display panel 10 to strengthen display effect.
The example for the intensity that ambient light is judged according to first threshold is described above, however, the invention is not restricted to this, also
The intensity of ambient light can be judged according to first threshold and less than the Second Threshold of first threshold.In this case, if
Control unit 13 determines that the light intensity of ambient light is more than default first threshold（Such as, 10000lux）, then control unit 13 control apply
It is added to the voltage of scattering unit 11 nephelometric turbidity unit of scattering unit 11 is set into the first nephelometric turbidity unit（Such as, 50%）, and if control
Unit 13 determines that the light intensity of ambient light is less than or equal to default Second Threshold（Such as, 1000lux）, then control unit 13 control apply
It is added to the voltage of scattering unit 11 nephelometric turbidity unit of scattering unit 11 is set into the second nephelometric turbidity unit（Such as, 0%）.In such case
Under, when control unit 13 determines that the intensity of ambient light is between first threshold and Second Threshold, control unit 13 can be with
The nephelometric turbidity unit of scattering unit 11 is arranged on the particular value between the first nephelometric turbidity unit and the second nephelometric turbidity unit（Such as, 25%）.
In addition, in example of the display panel 10 for such as Mirasol etc interference-type display panel, control unit 13
The species of ambient light can be determined based on ambient light data, and the control of the species based on ambient light is applied to scattering unit 11
Voltage.Here, the ambient light data that environment optical detecting unit 12 is produced can indicate the kind of the ambient light around display panel 10
Class.In this example, the species of ambient light can include direct light and scattered light.Here, environment optical detecting unit 12 can be with
Include multiple photo-sensitive cells towards different directions so that environment optical detecting unit 12 can obtain the ambient light in multiple directions
Data.In this case, control unit 13 can give the ambient light data in multiple directions to determine the species of ambient light.
For example, control unit 13 can be determined equivalent to the ambient light in the multiple directions of display panel 10 based on ambient light data.Such as
Fruit control unit 13 determines that the intensity of the ambient light in multiple directions is substantially suitable（Such as, within differing twice）, then control unit
13 determine that ambient light is scattered light, and if control unit 13 determines that the strength difference of the ambient light in multiple directions is very big（Such as,
Twice or more of difference）, then the determination of control unit 13 ambient light is direct light.
In this case, when it is direct light that control unit 13, which determines ambient light, control unit 13 can control to apply
To the voltage of scattering unit 11 so that the nephelometric turbidity unit of scattering unit 11 is set into the first nephelometric turbidity unit.In addition, true in control unit 13
When determining ambient light for scattered light, the control of control unit 13 is applied to the voltage of scattering unit 11 with by the nephelometric turbidity unit of scattering unit 11
It is set to the second nephelometric turbidity unit.
Here, similar with the description of embodiment before, the first nephelometric turbidity unit can be 50%, and the second nephelometric turbidity unit can be
0%.In this example, when ambient light is direct projection light value, the control of control unit 13 is applied to the voltage of scattering unit 11 to dissipate
The nephelometric turbidity unit for penetrating unit 11 is set to the first nephelometric turbidity unit（Such as, 50%）.In this case, it is irradiated on display panel 10
The light of ambient light by homogenous diffusion to display panel 10 to increase the visual angle of display panel 10.In addition, being scattered in ambient light
When penetrating light, the control of control unit 13 is applied to the voltage of scattering unit 11 and dissipated so that the nephelometric turbidity unit of scattering unit 11 is set into second
Degree of penetrating（Such as, 0%）.Here, although in the above example the first nephelometric turbidity unit be 50%, and the second nephelometric turbidity unit be 0%, but this
Invention not limited to this, as long as can be set to higher value to increase display panel 10 by the first nephelometric turbidity unit under direct solar environment
Visual angle, and the second nephelometric turbidity unit is set smaller than to the value of the first nephelometric turbidity unit under scattering luminous environment, the present invention is not scattered to first
The value of degree and the second nephelometric turbidity unit is limited.
, can be when ambient light be direct light by above-mentioned configuration, will by the scattering unit 11 with the first nephelometric turbidity unit
Direct light is changed into scattered light to increase the visual angle of display panel 10, and can be when ambient light is scattered light, by with low

It may apply on the terminal device shown in Fig. 1.Here, due to terminal device being described in detail above, because
Here only it is briefly described.Terminal device can include display panel, scattering unit and environment optical detecting unit
Etc..Display panel can be the display panel of such as oled panel, interference-type display panel etc.Scattering unit is arranged on aobvious
Show on panel（Fit or with space）, and the size of scattering unit is corresponding with display panel（It is identical or slightly larger）.Scattering
Unit can change the nephelometric turbidity unit of scattering unit based on the voltage for being applied to scattering unit.Here it is possible to by that can set respectively
The multiple electrodes in the both sides of scattering unit are put to change.In this case, when these multiple electrodes connect electricity, it can dissipate
The both sides for penetrating unit produce voltage difference.Environment optical detecting unit can be arranged on the optional position around display panel to examine
The ambient light and the generation ambient light data related to ambient light surveyed around display panel.
As shown in Fig. 2 in step S201, the ambient light around display panel is detected by environment optical detecting unit.In step
Rapid S202, produces the ambient light data related to ambient light.Then in step S203, it is applied to based on ambient light data control scattered
The voltage of unit is penetrated to change the nephelometric turbidity unit of scattering unit.
Specifically, in the example that display panel 10 is oled panel, under conditions of nephelometric turbidity unit regulatory function is enabled, ring
Ambient light around the detection display panel of border optical detecting unit 12.Here, the ambient light data that environment optical detecting unit 12 is produced
Indicate the light intensity of the ambient light around display panel 10.Then, control unit 13 receives ambient light from environment optical detecting unit 12
Data, and determine based on the ambient light data from environment optical detecting unit 12 light of the ambient light around display panel 10
By force, and based on the intensity control of identified ambient light it is applied to the voltage of scattering unit 11.
For example, when control unit 13 determines that the light intensity of ambient light is more than default first threshold, control unit 13 is controlled
It is applied to the voltage of scattering unit 11 nephelometric turbidity unit of scattering unit 11 is set into the first nephelometric turbidity unit.In addition, working as control unit
When the light intensity of 13 determination ambient lights is less than or equal to default first threshold, control unit 13 controls to be applied to the electricity of scattering unit
Press the nephelometric turbidity unit of scattering unit 11 being set to the second nephelometric turbidity unit.Here it is possible to set this to preset according to the intensity of outdoor optical
First threshold.For example, default first threshold can be used as using 10000lux.However, the invention is not restricted to this, as long as can be with
Strong light environment and low light environment are distinguished by first threshold, can also be using other light intensity as first threshold, it is, working as environment
When the intensity of light is more than first threshold, control unit 13 judges that terminal device 1 is in strong light environment, and small in the intensity of ambient light
When first threshold, control unit 13 judges that terminal device 1 is in low light environment.In addition, the first nephelometric turbidity unit can be
50%, and the second nephelometric turbidity unit can be 0%.In this example, when the light intensity of ambient light is more than default first threshold, control is single
The control of member 13 is applied to the voltage of scattering unit 11 nephelometric turbidity unit of scattering unit 11 is set into the first nephelometric turbidity unit（50%）.
In this case, a part for the ambient light being irradiated on display panel 10（50%）Absorbed, and remaining light is equal
It is even to scatter on display panel 10 thus without the self-luminous for significantly affecting display unit 10.Therefore, too strong ambient light is to aobvious
Show that the influence of the display effect of panel 10 is reduced significantly.In addition, the light intensity in ambient light is less than or equal to default first threshold
During value, because environmental light intensity is relatively low, therefore ambient light will not also significantly affect display surface even if being irradiated on display panel 10
The display effect of plate 10.In this case, the control of control unit 13 is applied to the voltage of scattering unit 11 with by scattering unit
11 nephelometric turbidity unit is set to the second nephelometric turbidity unit（0%）.Now, due to the nephelometric turbidity unit of scattering unit 11 is set into the second nephelometric turbidity unit
（0%）, therefore the light sent from display panel 10 can which thereby enhance display panel also nondestructively directly by scattering unit 11
10 brightness.In this case, the brightness even if display panel 10 sets relatively low also not interfering with the aobvious of display panel 10
Show effect（And this can increase the endurance of terminal device 1）.Here, although the first nephelometric turbidity unit is in the above example
50%, and the second nephelometric turbidity unit is 0%, but the invention is not restricted to this, as long as the first nephelometric turbidity unit can be set under strong light environment
Higher value is set to reduce influence of the strong ambient light to display panel 10, and is set to the second nephelometric turbidity unit under low light environment
Less than the value of the first nephelometric turbidity unit to reduce the self luminous absorption to display panel 10, the present invention is not to the first nephelometric turbidity unit and the
The value of two nephelometric turbidity units is limited.In this case, when ambient light intensity is higher, the scattering with the first nephelometric turbidity unit is passed through
Unit 11 reduces influence of the ambient light to the display effect of display panel 10, and when ambient light intensity is relatively low, by with
The scattering unit 11 of second nephelometric turbidity unit reduces the self luminous influence on display panel 10 to strengthen display effect.
The example for the intensity that ambient light is judged according to first threshold is described above, however, the invention is not restricted to this, also
The intensity of ambient light can be judged according to first threshold and less than the Second Threshold of first threshold.In this case, if
