Elaborate a lot of details in the following description in order to fully understand the present invention, but the present invention is acceptable To be implemented different from other modes described here using other.Therefore, the present invention is not limited to following public being embodied as The restriction of example.
For Transflective device in background technology absorbance too high lead to display system imaging when figure, scape merge effect Really bad problem, present inventor proposes the thinking reducing Transflective device absorbance.Reduce transflector The absorbance of part can ensure that the image quality of the become virtual image of electronic display unit display image, but but can reduce Transflective The transit dose of the true scenery in device rear, also can affect figure, the effect of scape fusion, reduce the image quality of display system.For thorough Bottom solves the problems, such as that figure, scape syncretizing effect are bad, and applicant of the present invention proposes following solution：Reduce transflector Increase the brightness at Transflective device rear when the absorbance of part is simultaneously necessary, to compensate to environmental light brightness, Thus the transit dose of the true scenery in Transflective device rear, Jin Erbao can be increased while ensureing virtual image forming quality again Demonstrate,prove figure, the effect of scape fusion, improved the image quality of display system, lift user's visual experience.
Based on above-mentioned design, the embodiment of the present invention proposes a kind of method adjusting display system image quality.This place The display system being related to, the display device including electronic display unit with for assisting this display electronic equipment display image.Electricity Sub- display device and display device, can be detached or become one physically.Real in the present invention Apply in example, the mode of display device auxiliary electron display device display image is identical with mode used in background technology, different , this display device have an absorbance be less than first threshold Transflective device.Wherein, this first threshold is less than background The absorbance of involved Transflective device in technology, its span can be 30%-50%, and such as first threshold is permissible For 40%.Meanwhile, electronic display unit can be Two-dimensional electron display device, such as two-dimentional smart mobile phone, two-dimensional flat plate computer, Can be three-dimensional electronic display device (including spectacle three-dimensional display apparatus and bore hole formula three-dimensional display apparatus), such as naked eye three-dimensional Smart mobile phone, naked eye three-dimensional panel computer.
As shown in figure 1, being the schematic flow sheet of the method adjusting display system image quality provided in an embodiment of the present invention, Comprise the steps：
Step S11, when meeting pre-conditioned, generates brightness regulation indication signal, described brightness regulation indication signal is used Increase the brightness at described Transflective device rear in instruction；
In all embodiments of the method for the present invention, executive agent can be the display dress of auxiliary electron display device display image Put it is also possible to be independently of a brightness controlling device outside display system.
The effect of brightness regulation indication signal is：Point out the son residing for currently displaying system to make environmental light brightness not enough, need Increase the brightness at Transflective device rear, to increase the transit dose of the true scenery through Transflective device.This In bright embodiment, just can generate brightness regulation indication signal when meeting default condition, need increase transmission anti-in other words Brightness regulation indication signal just can be generated, with to display system local environment during the situation of emitter part rear true scenery transit dose Ambient light compensate, lifting display system figure, scape merge effect, improve user's visual experience.
Step S12, according to the instruction of the brightness regulation indication signal generating in step S11, in display system local environment Environmental light brightness on the basis of increase the brightness at described Transflective device rear；
Wherein, the method increasing Transflective device rear brightness has multiple, for example, opens independent of display device One illuminating source, to increase the brightness at Transflective device rear；For example open the luminous light being arranged in display device again Source, to increase the brightness at Transflective device rear.Wherein, illuminating source can be LED light source, can carry out tone and colour temperature Regulation.When opening illuminating source, can automatically turn on it is also possible to manually opened.
In the embodiment of the present invention, when meeting pre-conditioned, generate and increase Transflective device rear light for mark The brightness regulation indication signal of degree, and increase the brightness at Transflective device rear according to the instruction of this Regulate signal, that is, exist When needing the situation increasing the true scenery transit dose in Transflective device rear, in the environmental light brightness of display system local environment On the basis of increase Transflective device rear brightness, the environmental light brightness of display system local environment is compensated, with The figure of lifting display system, scape syncretizing effect and picture quality, improve the visual experience of user.
It should be noted is that, this is pre-conditioned be according to impact electronic display unit display image image quality because Element sets, and this factor can be for example the longitudinal degree of electronic display unit display image, electronic display unit local environment Environmental light brightness, the resolution of electronic display unit, brightness of electronic display unit display screen etc..
Need explanation on the other hand, in Fig. 1 the concrete operation method of step S11 can have multiple.Due to default bar Part can have multiple, therefore accordingly generate brightness regulation indication signal method also have multiple.Set pre-conditioned when, be from The factor of impact electronic display unit display image image quality sets, for example can be from electronic display unit display image The angle of longitudinal degree is setting pre-conditioned it is also possible to set pre- from the angle of the environmental light brightness of display system local environment If condition, will be described respectively by the corresponding embodiment of Fig. 2, Fig. 3 below.
As shown in Fig. 2 being the schematic flow sheet of the method adjusting display system image quality provided in an embodiment of the present invention, Comprise the steps：
Step S21, obtains the actual depth value for identifying electronic display unit display image longitudinal degree；
The image content of electronic display unit display image is different, and its corresponding longitudinal degree also differs.For example, work as electricity The 3-D view that sub- display device shows be one be continuous road without cease when, now picture depth feelings are stronger, and this picture is corresponding Actual depth value is then larger, and now user has the demand seeing farther scenery clearly.Again for example, the three-dimensional showing when electronic display unit When image is narrow space or airtight space, now picture depth feelings are then weaker, and corresponding depth value is then smaller, now User does not see the demand of scenery farther out substantially clearly.Therefore, it can the depth of concrete image content showing according to electronical display Value, decides whether to increase the brightness at Transflective device rear.When picture depth feelings are stronger, transflector can be increased The brightness at part rear, through more true scenery, to meet user's request；When picture depth feelings are weaker it may be considered that Do not increase the brightness at Transflective device rear, therefore now user does not almost watch the demand of more true scenery, can With energy saving.
Step S22, when the actual depth value obtaining is more than default first standard depth value, generates brightness regulation instruction Signal.
Before generating brightness regulation indication signal, can first judge whether to increase the brightness at Transflective device rear. Its method is, sets a reference value, i.e. described the first standard depth value in step S22, and by the actual depth value obtaining with First standard depth value is compared.When the actual depth value of the electronic display unit display image obtaining is more than this first standard It is believed that the depth feelings of this display image are stronger during depth value, the brightness at Transflective device rear can be increased, generate brightness Adjust indication signal.When the actual depth value of the electronic display unit display image obtaining is less than or equal to this first standard depth It is believed that the depth feelings of this display image are weaker during value, the brightness not increasing Transflective device rear does not interfere with regarding of user Feel experience, therefore do not generate brightness regulation indication signal.
In step S22, if generating brightness regulation indication signal, next then can execute and step S13 identical Step, i.e. the instruction according to this brightness regulation indication signal, increase on the basis of the environmental light brightness of display system local environment The brightness at Transflective device rear, compensates to environmental light brightness, so that more true scenery can pass through transmission Reflection device, mirrors eyes of user, lifting figure, scape syncretizing effect, improves user's visual experience.
Further, when execution increases the brightness at Transflective device rear, it is to be referred to by brightness regulation indication signal Show.The brightness of brightness regulation indication signal instruction is probably the brightness values of a concrete increase it is also possible to actual depth Difference between value and the first standard depth value, different differences is corresponding to increase different brightness.Therefore, increase thoroughly in execution Penetrate reflection device rear brightness when, can have two ways.I.e. in concrete execution, with execution step S23, or can hold Row step S24- step S25.
Step S23, increases by the first brightness at Transflective device rear, this first brightness is this brightness regulation indication signal The brightness values indicating.
Wherein, this first brightness is probably a random value it is also possible to a preset fixed value.
Step S24, the difference between the actual depth value according to the instruction of brightness regulation indication signal and the first standard depth value Value, determines corresponding second brightness of this difference.
Step S26, increases by the second brightness at Transflective device rear.
In step S24- step S25, the second brightness is with the difference between actual depth value and the first standard depth value Increasing is in increase trend.That is, difference is bigger, the brightness of increase is also bigger.
Specifically, the second brightness is in increase trend with the increase of difference, and what this increase trend possibly increased continuously becomes Gesture it is also possible to saltus step increase trend.When this increase trend is the trend increasing continuously, between the second brightness and difference it is in Linear or curve linear relationship, according to default linear or curve equation, you can to determine the second brightness.When this increase trend is to jump When becoming increase, need to pre-set multiple different brightness increase grades, and different brightness increases grade corresponding difference model Enclose, the different brightness values of different difference range correspondences, concrete method to set up can be as shown in table 1 below.By table 1, you can look for To corresponding second brightness of corresponding difference.
Table 1 brightness increases grade-brightness values scope synopsis
Brightness increases grade Brightness values Difference range
First increase grade 5 0-10
Second increase grade 15 10-30
3rd increase grade 25 >30
In table 1, according to the difference of brightness regulation indication signal instruction, determine the corresponding brightness values of this difference, then Carrying out corresponding brightness according to the brightness values determined increases operation.It is understood that the numerical value in table 1 can basis Different demands set different numerical value.
In the embodiment of the present invention, by execution step S21- step S25, in electronic display unit display image longitudinal degree When actual depth value is more than default first standard depth value, generates and increase the bright of Transflective device rear brightness for instruction Degree adjusts indication signal, and the environmental light brightness of display system local environment is compensated.In the concrete operation increasing brightness, The concrete numerical value of brightness can be increased to select any one of above two mode to determine.The scheme of the embodiment of the present invention can Effect and image quality that lifting figure, scape merge, improve the visual experience of user.
Further, for lifting user's visual experience further, the method for the embodiment of the present invention can also include walking as follows Suddenly：
Step S26, the tone of display image and colour temperature when obtaining electronic display unit display.
Step S27, increases according to tone regulation corresponding with the colour temperature Transflective device rear of the display image obtaining The tone of light and colour temperature.
In step S26- step S27, by the tone of display image and colour temperature when obtaining electronic display unit display, and phase The tone of the light of Transflective device rear increase and colour temperature should be adjusted to the tone and colour temperature with the display image obtaining ground Unanimously, figure, the colour temperature of scape and tone is so then made to be not in indisposed sense, lifting figure, scape syncretizing effect, improve vision body Test.
In implementing it is assumed that the tone getting electronic display unit display image be blue, green light and colour temperature colder when, The tone of the light then increasing Transflective device rear is adjusted to indigo plant, green light, and colour temperature is adjusted to cool colour temperature；When electronic display unit shows When the tone of diagram picture is that red, yellow and colour temperature is partially warm, then the tone of light Transflective device rear being increased also be adjusted to red, Huang, colour temperature is adjusted to warm colour temperature.Such regulation makes our compensation light more get along swimmingly with each other with display image, greatly avoids The strongly indisposed sense that brings to user because of tone difference, now user be even detectable the compensation light of one additional.
It should be noted that step S21- step S27 is circulation execution, it exits the condition of circulation is：Electronical display Equipment is closed and is shown it is not necessary to carry out image.
Refer to Fig. 3, be the schematic flow sheet of the method adjusting display system image quality provided in an embodiment of the present invention, Comprise the steps：
Step S31, the display image when environmental light brightness of acquisition display system local environment, electronic display unit display Brightness.
The effect that the environmental light brightness of display system local environment can merge on figure, scape produces impact.Implement in the present invention In example, brightness ratio when will be more excellent to figure, scape syncretizing effect is referred to as normal brightness ratio.Brightness of image is shown by electronic display unit When showing, the brightness of display image determines.And the brightness of scenery is then made up of two parts, a part is surrounding brightness, Another part is to compensate brightness, that is, the brightness at the Transflective device rear increasing.Therefore, determining whether to generate brightness Before adjusting indication signal, show when environmental light brightness and the electronic display unit display that can first obtain display system local environment The brightness of diagram picture.
Step S32, when the ratio of the environmental light brightness obtaining and the brightness of display image is less than default normal brightness Than when, generate brightness regulation indication signal.
Before generating brightness regulation indication signal, when judging whether the brightness increasing Transflective device rear, its Method is that setting a reference value is normal brightness ratio, its brightness ratio when preferable for mark figure, scape syncretizing effect, and will The environmental light brightness obtaining and the ratio of the brightness of display image.Brightness when the environmental light brightness obtaining and display image Ratio when being less than default normal brightness ratio, illustrate that now environmental light brightness is inadequate, needs environmental light brightness is compensated, Brightness regulation indication signal therefore can be generated.When the environmental light brightness of detection is more than with the ratio of the brightness of display image or waits When default normal brightness ratio, then explanation environmental light brightness enough, can be increased without compensating light.
In step s 32, if generating brightness regulation indication signal, next then can execute and step S13 identical Step, i.e. the instruction according to this brightness regulation indication signal, increase on the basis of the environmental light brightness of display system local environment The brightness at Transflective device rear.
Further, when execution increases the brightness at Transflective device rear, in concrete execution, step can be executed Rapid S33, can also execution step S34- step S37.
Step S33, increases by the 3rd brightness at Transflective device rear, makes environmental light brightness and the 3rd brightness sum and shows The ratio of the brightness of diagram picture is equal to normal brightness ratio.
3rd brightness is the brightness values of brightness regulation indication signal instruction, and the determination mode of the 3rd brightness is：Make Environmental light brightness and the 3rd brightness sum are equal to default normal brightness ratio with the ratio of the brightness of display image.
After increased the 3rd brightness, environmental light brightness to external world has carried out compensation so that environmental light brightness and the 3rd Brightness sum is consistent with normal brightness ratio with the ratio of display image brightness, therefore, now so that figure, scape syncretizing effect Preferably, lift the image quality of display system.
From unlike step S33, in step S34- step S37, after determining the 3rd brightness to be increased, no It is the brightness values immediately according to the instruction of Signal Regulation indication signal, i.e. the 3rd brightness compensates to environmental light brightness, but Also contemplate another factor of impact figure, scape syncretizing effect, i.e. the longitudinal degree of electronic display unit display image.Electronical display The image content of equipment display image is different, and its corresponding longitudinal degree also differs.For example, when electronic display unit shows 3-D view be one be continuous road without cease when, now picture depth feelings are stronger, and the corresponding actual depth value of this picture is then larger, Now user has the demand seeing farther scenery clearly.Again for example, the narrow space of the 3-D view that shows when electronic display unit or During airtight space, now picture depth feelings are then weaker, and corresponding depth value is then smaller, and now user does not see clearly relatively substantially The demand of distant view thing.Therefore, it can the depth value of concrete image content showing according to electronical display, decide whether anti-to transmission The brightness that emitter part rear increases is finely adjusted.When picture depth feelings are stronger, can be on the basis of increasing by the 3rd brightness Floating certain proportion, through more true scenery, to meet user's request；When picture depth feelings are weaker, can increase Floating certain proportion on the basis of 3rd brightness, with through more true scenery, energy saving.Therefore, it can vertical according to this Depth, does corresponding fine setting to the 3rd brightness, so that figure, scape syncretizing effect are more preferable.
Step S34, obtains the actual depth value for identifying electronic display unit display image longitudinal degree.
Step S35, calculates the difference of actual depth value and default second standard depth value；
Step S36, when this difference is more than or equal to zero, the brightness increasing at Transflective device rear is the 3rd Float on the basis of brightness the first ratio, and this first ratio increases with the increase of difference；
Step S37, when this difference is less than zero, the brightness increasing at Transflective device rear is in the 3rd brightness base Float downward on plinth the second ratio, this second ratio increases with the increase of described absolute difference；
In step S34- step S37, its basic ideas is, display image when showing yet further still according to electronic display unit Longitudinal degree, determine the concrete brightness compensating.Obtain the actual depth of electronic display unit display image by step S34 Value, and the actual depth value obtaining is compared with the second standard depth value set in advance, and according to comparative result, that is, real Difference between border depth value and the second standard depth value set in advance, determines specific compensation brightness.Specifically, It is according to difference, select a suitable step execution from step S36- step S37.Wherein, the 3rd brightness is brightness regulation The brightness values of indication signal instruction.
In step S36, when this difference is more than zero, the brightness increasing at Transflective device rear is bright the 3rd Float on the basis of degree the first ratio, and the brightness increasing at Transflective device rear is：(1+ first compares 3rd brightness * Example).Wherein, this first ratio increases with the increase of this difference, and that is, difference is bigger, and the first ratio of floating is also bigger.Should The first ratio floating, can set a higher limit, and such as 10%.Within the scope of can floating, this first ratio is permissible Change with difference is in consecutive variations trend it is also possible to the change with difference is in saltus step trend.
In step S37, when this difference is less than zero, the brightness increasing at Transflective device rear is bright the 3rd Float downward on the basis of degree the second ratio, the brightness increasing at Transflective device rear is：(1- second compares 3rd brightness * Example).Wherein, this second ratio increases with the increase of this absolute difference, and that is, the corresponding absolute value of difference is bigger, floats downward Second ratio is also bigger.This secondth ratio floated downward, can set a higher limit, and such as 10%.In the scope that can float downward Within, this second ratio can be in consecutive variations trend with the change of absolute difference it is also possible to change with absolute difference In saltus step trend.
This kind of mode determining increased brightness, considers two factors of impact figure, scape syncretizing effect simultaneously, that is, draws Face longitudinal degree and surrounding environment light, therefore, it is possible to the effect lifting figure further, scape merges.
Further, for lifting user's visual experience further, the method for the embodiment of the present invention can also include walking as follows Suddenly：
Step S38, when described environmental light brightness increases, the 3rd brightness is adjusted to the 4th brightness, and described 4th brightness Less than described 3rd brightness；
When the environmental light brightness of surrounding increases, in the presence of ambient light, enter human eye through Transflective device True scenery can increase.Therefore, now it is contemplated that reducing the brightness increasing at Transflective device rear, that is, turn down the 3rd bright 3rd brightness is adjusted to the 4th brightness and the 4th brightness and is less than the 3rd brightness by degree in other words so that the 4th brightness after turning down with Current environmental light brightness sum is equal to normal brightness ratio with the ratio of the brightness values of display image, is so ensureing figure, Jing Rong On the basis of closing quality, power supply can be saved again.Extreme situation is, the environmental light brightness of surrounding sufficiently large so that ambient light Brightness is more than or equal to normal brightness ratio with the ratio of the brightness values of display image, now can adjust the numerical value of the 4th brightness For 0.
Step S39, the tone of display image and colour temperature when obtaining electronic display unit display.
Step S310, increases according to tone regulation corresponding with the colour temperature Transflective device rear of the display image obtaining The tone of light and colour temperature.
In step S39- step S310, by obtaining tone and the colour temperature of electronic display unit display image, and correspondingly The tone of light that increase Transflective device rear and colour temperature are adjusted to consistent with the tone and colour temperature of the display image obtaining, Such then figure, the colour temperature of scape and colour temperature are not in indisposed sense, lifting figure, scape syncretizing effect, raising visual experience.
In implementing it is assumed that the tone getting electronic display unit display image be blue, green light and colour temperature colder when, The tone of the light then increasing Transflective device rear is adjusted to indigo plant, green light, and colour temperature is adjusted to cool colour temperature；When electronic display unit shows When the tone of diagram picture is that red, yellow and colour temperature is partially warm, then the tone of light Transflective device rear being increased also be adjusted to red, Huang, colour temperature is adjusted to warm colour temperature.Such regulation makes our compensation light more get along swimmingly with each other with display image, greatly avoids The strongly indisposed sense that brings to user because of tone difference, now user be even detectable the compensation light of one additional.
It should be noted that step S31- step S310 is circulation execution, it exits the condition of circulation is：Electronical display Equipment is closed and is shown it is not necessary to carry out image.

Need to say, because default condition can have multiple, brightness regulation indicating circuit generation brightness regulation instruction The method of signal also has multiple.When setting pre-conditioned, can be from the angle of the longitudinal degree of electronic display unit display image To set pre-conditioned it is also possible to set pre-conditioned from the angle of the environmental light brightness of display system local environment.And, Because the structure of brightness regulation indication signal circuit is different, accordingly, the structure of control circuit for light source is also different, below will It is described respectively by Fig. 8-9, Figure 10-11.
As Figure 8-9, be the embodiment of the circuit structure of display device provided in an embodiment of the present invention structured flowchart, In the circuit structure of this display device, if when generating brightness regulation indication signal, be to determine from the angle of image longitudinal degree 's.The circuit structure of this display device includes：Brightness regulation indication signal indicating circuit 15 and control circuit for light source 16.
Wherein, brightness regulation indicating circuit 15 specifically includes：
First acquisition module 151, for obtaining the actual depth value of mark electronic display unit display image longitudinal degree；
The image content of electronic display unit display image is different, and its corresponding longitudinal degree also differs.When actual vertical When value is larger deeply, now user has the demand seeing farther scenery clearly, and when depth value is smaller, now user does not see clearly substantially The demand of scenery farther out.Therefore, it can the depth value of concrete image content showing according to electronical display, decide whether to increase thoroughly Penetrate the brightness at reflection device rear.
First brightness regulation indication signal generation module 152, for the actual depth value obtaining when the first acquisition module 151 During more than default first standard depth value, generate the first brightness regulation indication signal.
Before generating the first brightness regulation indication signal, can first judge whether to increase the bright of Transflective device rear Degree.Its method is, sets a reference value, i.e. the first standard depth value, and by the actual depth value obtaining and the first standard depth Value is compared.When the actual depth value of the electronic display unit display image obtaining is more than this first standard depth value, recognize Stronger for the depth feelings of this display image, the brightness at Transflective device rear can be increased, now, the first brightness regulation refers to Show that signal generation module 152 generates the first brightness regulation indication signal.Reality when the electronic display unit display image obtaining Depth value is less than or equal to during this first standard depth value it is believed that the depth feelings of this display image are weaker, does not increase Transflective The brightness at device rear does not interfere with the visual experience of user, does not therefore generate the first brightness regulation indication signal.
Control circuit for light source 16, the first brightness regulation generating in the first brightness regulation indication signal generation module 152 refers to Show signal, you can open illuminating source 14 to control, to increase the brightness at Transflective device rear.
Now, control circuit for light source 16 specifically has two kinds of structures：
The first structure is：Control circuit for light source 16 includes the first brightness control module 161, opens luminous light for controlling Source and make illuminating source luminosity be the first brightness；Wherein, this first brightness is the first brightness regulation indication signal instruction Brightness values.Now, the circuit structure of display device is as shown in Figure 8.
Second structure is：Control circuit for light source 16 includes the first determining module 162 and the second brightness control module 163. Now, the circuit structure of display device is as shown in Figure 9.
Wherein it is determined that module 162, for the actual depth value according to the first brightness regulation indication signal instruction and the first mark Difference between quasi- depth value, determines corresponding second brightness of this difference, and wherein this second brightness with the increase of this difference is in Increase trend.The trend that possibly increased continuously due to the increase trend of the second brightness is it is also possible to the increased trend of saltus step.When When this increase trend is the trend increasing continuously, linear or curve linear relationship, determining module 162 between the second brightness and difference According to default linear or curve equation, you can to determine the second brightness.When this increase trend is that saltus step increases, determining module 162 can determine corresponding second brightness of corresponding difference according to above-mentioned table 1.Second brightness control module 163, for controlling Open illuminating source 14 and make this illuminating source 14 luminosity be the second brightness, this second brightness be equal to the first determining module 162 brightness determined.
Display device disclosed in the embodiment of the present invention is big in the actual depth value of electronic display unit display image longitudinal degree When default first standard depth value, generate the brightness regulation instruction letter increasing the rear brightness of Transflective device for instruction Number, the ambient light of electronic display unit local environment is compensated, figure, the effect of scape fusion and image quality can be lifted, Improve the visual experience of user.
Further, the display device shown in Fig. 8, Fig. 9 also includes：It is arranged at the tone colour temperature testing circuit of support member 17, for the tone of display image and colour temperature when detecting electronic display unit display.Control circuit for light source 16, also includes：Colour temperature Tone adjustment module 167, this colour temperature tone detection module 167 is used for the display figure detecting according to tone colour temperature testing circuit 17 The tone of picture and colour temperature, the corresponding tone adjusting illuminating source and colour temperature
The tone of electronic display unit display image and colour temperature are detected by tone colour temperature testing circuit 17, and by detection The tone of electronic display unit display image and colour temperature issue the colour temperature tone adjustment module 167 of control circuit for light source 16.Colour temperature Transflective device rear accordingly can be increased by tone adjustment module 167 according to the tone of the display image receiving and colour temperature The tone of light and colour temperature adjust to consistent with the tone and colour temperature of display image, so then figure, the colour temperature of scape and colour temperature will not Indisposed sense, lifting figure, scape syncretizing effect occur, improves visual experience.
In implementing it is assumed that the tone getting electronic display unit display image be blue, green light and colour temperature colder when, The tone of the light then increasing Transflective device rear is adjusted to indigo plant, green light, and colour temperature is adjusted to cool colour temperature；When electronic display unit shows When the tone of diagram picture is that red, yellow and colour temperature is partially warm, then the tone of light Transflective device rear being increased also be adjusted to red, Huang, colour temperature is adjusted to warm colour temperature.Such regulation makes our compensation light more get along swimmingly with each other with display image, greatly avoids The strongly indisposed sense that brings to user because of tone difference, now user be even detectable the compensation light of one additional.
As shown in figs. 10-11, be the circuit structure of display device provided in an embodiment of the present invention structured flowchart, this display In the circuit structure of device, when whether generating brightness regulation indication signal, it is the angle from display device local environment brightness Come to determine.The circuit structure of this display device includes：Brightness regulation indicating circuit 15 and control circuit for light source 16.
Wherein, brightness regulation indicating circuit 15 specifically includes：Second acquisition module 153 and the second brightness regulation indication signal Generation module 154.
Wherein, the second acquisition module 153, for obtaining environmental light brightness, the electronic display of display device local environment brightness The brightness of display image when showing equipment display；
The effect that the environmental light brightness of display device local environment can merge on figure, scape produces impact.The embodiment of the present invention In, brightness ratio when will be more excellent to figure, scape syncretizing effect is referred to as normal brightness ratio.Brightness of image is shown by electronic display unit When display image brightness determine.And the brightness of scenery is then made up of two parts, a part is surrounding brightness, separately A part is to compensate brightness, that is, the brightness at the Transflective device rear increasing.Therefore, determining whether that generating brightness adjusts Before section indication signal, show when environmental light brightness and the electronic display unit display that can first obtain display device local environment Brightness during image.
Second brightness regulation indication signal generation module 154, for the environmental light brightness obtaining when the second acquisition module 153 When being less than default normal brightness ratio with the ratio of the brightness of this display image, generate the second brightness regulation indication signal.
Second brightness regulation indication signal generation module 154, before generating the second brightness regulation indication signal, needs to sentence During the brightness whether increasing Transflective device rear of breaking, its method is to set a reference value, i.e. normal brightness ratio, its use Brightness ratio when mark scape syncretizing effect is preferable.When the environmental light brightness of detection is little with the ratio of the brightness of display image When default normal brightness ratio, illustrate that now environmental light brightness not, needs environmental light brightness is compensated, therefore can give birth to Become the second brightness regulation indication signal.When the environmental light brightness of detection is more than or equal in advance with the ratio of the brightness of display image If normal brightness ratio when, then explanation environmental light brightness enough, can be increased without compensating light.
Control circuit for light source 16, the second brightness regulation generating in the second brightness regulation indication signal generation module 154 refers to Show signal, you can open illuminating source 14 to control, to increase the brightness at Transflective device rear.
Now, control circuit for light source 16 specifically has two kinds of structures：
The first structure is：Control circuit for light source 16 includes the 3rd brightness control module 164, opens luminous light for controlling Source and make illuminating source brightness be the 3rd brightness；Now, the circuit structure of display device is as shown in Figure 10.
Wherein, the 3rd brightness is the brightness values of the second brightness regulation indication signal instruction, the determination mode of the 3rd brightness It is：Environmental light brightness and the 3rd brightness sum and the ratio of the brightness of display image is made to be equal to default normal brightness ratio.? After increased the 3rd brightness, environmental light brightness to external world has carried out compensation so that environmental light brightness and the 3rd brightness sum Consistent with normal brightness ratio with the ratio of the brightness value of display screen, now so that figure, scape syncretizing effect preferably, improve into As quality.
Second structure is：It is bright that control circuit for light source 16 includes the 3rd acquisition module 165, computing module 166 and the 3rd Degree control module 164.
In second structure, after determining the 3rd brightness to be increased, it is not to be indicated according to Signal Regulation immediately The brightness values of signal designation, i.e. the 3rd brightness compensates to environmental light brightness, but also contemplates impact figure, scape fusion effect Another factor of fruit, i.e. the longitudinal degree of electronic display unit display image.The image content of electronic display unit display image Different, its corresponding longitudinal degree also differs.For example, when the 3-D view that electronic display unit shows be one be continuous without cease Road when, now picture depth feelings are stronger, and the corresponding actual depth value of this picture is then larger, and now user has and sees farther scenery clearly Demand.Again for example, when the narrow space of the 3-D view that electronic display unit shows or airtight space, now picture is indulged Feel then weaker deeply, corresponding depth value is then smaller, now user does not see the demand of scenery farther out substantially clearly.Therefore, it can The depth value of the concrete image content being shown according to electronical display, decides whether the brightness that Transflective device rear is increased It is finely adjusted.When picture depth feelings are stronger, can increase the 3rd brightness on the basis of floating certain proportion, with through more True scenery, meet user's request；When picture depth feelings are weaker, can float on the basis of increasing by the 3rd brightness certain Ratio, with through more true scenery, energy saving.Therefore, it can, according to this longitudinal degree, the 3rd brightness be done micro- accordingly Adjust, so that figure, scape syncretizing effect are more preferable.
3rd acquisition module 165, for obtaining the actual depth for identifying electronic display unit display image longitudinal degree Value；Computing module 166, for calculating actual depth value and the default second standard depth value that the 3rd acquisition module 165 obtains Difference；3rd brightness control module 164, for when the difference that computing module 164 calculates is more than or equal to zero, for controlling Open described illuminating source, and make the brightness of described illuminating source be first ratio that floats on the basis of the 3rd brightness, that is, exist Transflective device rear increase brightness be：3rd brightness * (1- second ratio), wherein, this first ratio is with this difference The increase of value and increase, that is, difference is bigger, and the first ratio of floating is also bigger.First ratio of this floating, can set one Higher limit, such as 10%.Within the scope of can floating, this first ratio can be in consecutive variations trend with the change of difference, Can also be in saltus step trend with the change of difference；When difference is less than zero, open described illuminating source for controlling, and make described The brightness of illuminating source is the second ratio of floating downward on the basis of the 3rd brightness, the light increasing at Transflective device rear Spend and be：3rd brightness * (1- second ratio).Wherein, this second ratio increases with the increase of this absolute difference, i.e. difference Bigger, the second ratio floated downward is also bigger.This secondth ratio floated downward, can set a higher limit, and such as 10%.Can Within the scope of floating downward, this second ratio can be in consecutive variations trend it is also possible to exhausted with difference with the change of absolute difference Change to value is in saltus step trend.Wherein, the 3rd brightness is the brightness values of the second brightness regulation indication signal instruction.
That is, after determining the 3rd brightness, the image that shows yet further still according to electronic display unit vertical Depth, determines the concrete brightness values compensating.The reality of electronic display unit display image is obtained by the 3rd acquisition module 165 Border depth value, and the difference between actual depth value and the second standard depth value is calculated by computing module 166, it is sent to Three brightness control module 164.3rd brightness control module 164 will select a suitable compensation brightness according to difference result Value.This kind of mode determining compensation brightness values, considers two factors of impact figure, scape syncretizing effect simultaneously, and that is, picture is indulged Depth and surrounding environment light, therefore, it is possible to the effect lifting figure further, scape merges.
It should be noted that the 3rd described brightness, can specifically set, it can be identical with first brightness of Fig. 8-9, also may be used With difference.
Further, the second brightness regulation indication signal generation module 154, is additionally operable to obtain in the second acquisition module 153 Environmental light brightness when increasing, generate new the second brightness regulation indication signal；
3rd brightness control module 164, is additionally operable to control described illuminating source 14, and makes the light of described illuminating source 14 Spend for the 4th brightness, the increased brightness in Transflective device rear will be adjusted to the 4th brightness, the 4th brightness is new the Two brightness regulation indication signals instruction brightness values and be less than the 3rd brightness.That is, when the environmental light brightness of surrounding increases When big, in the presence of ambient light, the true scenery entering human eye through Transflective device can increase.Therefore now it is contemplated that Reduce the brightness increasing at Transflective device rear, that is, turn down the 3rd brightness, in other words the 3rd brightness is adjusted to the 4th brightness And the 4th brightness be less than the 3rd brightness, so that the light of the 4th brightness after turning down and current environmental light brightness sum and display image The ratio of brightness value is equal to normal brightness ratio, so on the basis of ensureing figure, scape fusion mass, can save power supply again.Pole End situation be, the environmental light brightness of surrounding sufficiently large so that environmental light brightness is big with the ratio of the brightness values of display image In or be equal to normal brightness ratio, now the numerical value of the 4th brightness can be adjusted to 0.
Further, this display device also includes：It is arranged at the tone colour temperature testing circuit 17 of support member, for detecting The tone of display image and colour temperature during electronic display unit display.Control circuit for light source 16, also includes：Colour temperature tone adjustment module 167, the tone of display image and colour temperature that this colour temperature tone detection module 167 detects according to tone colour temperature testing circuit 17, The corresponding tone adjusting illuminating source and colour temperature
