Embodiment
Please refer to Fig. 1, it illustrates the functional block diagram according to the color data detection system of the display of preferred embodiment of the present invention.Color data detection system 100 comprises a broadcast control device 102, a color analytical equipment 104 and an automatic detection device 106.Broadcast control device 102 comprises a picture storage element 108, one first timing unit 110 and a broadcast unit 112.Picture storage element 108 for example is several monochromatic pictures, as a black picture, a white picture, a red picture, a green picture and a blue picture in order to store number pictures (not illustrating).First timing unit 110 is in send a picture switching signal S1 every an interval time.Broadcast unit 112 in order to picture playing on a display 114, and when receiving picture switching signal S1, the action of switching picture.
Automatic detection device 106 comprises one second timing unit 118, a data acquisition unit 120, a record cell 122 and a judging unit 124.When second timing unit 118 receives picture switching signal S1, in interval time, send at least one data acquisition signal S2.When data acquisition unit 120 received data acquisition signal S2, data acquisition unit 120 captured the color data that color analysis device 116 is analyzed according to data acquisition signal S2.And color data is recorded in record cell 122, and also in order to write down a normal data, normal data is in order to compare with color data to record cell 122.Whether and judging unit 124 is in order to compare normal data and color data, unusual to judge color data.
In addition, the automatic detection device 106 of present embodiment is to electrically connect with external mode and color analysis device 104.Yet as long as through a suitably design, automatic detection device 106 also can be arranged in the same body (not illustrating) with color analysis device 104, and forms a color analysis instrument with automatic detection device, to increase Portability or ease of use.
Please refer to Fig. 2, it illustrates the process flow diagram according to the color data detection method of the display of preferred embodiment of the present invention.At first, asking the while with reference to Fig. 1, in step S202, with picture, for example is a black picture, a white picture, a red picture, a green picture and a blue picture, is played on the display 114.
Then, please be simultaneously with reference to Fig. 3, it illustrates the sequential chart of the display playing pictures of present embodiment.In step S204, first timing unit 110 just sends picture switching signal S1 to the broadcast unit 112 and second timing unit 118 simultaneously every interval time during Δ T.Picture switching signal S1 is sending after the color detection function that starts color data detection system 100.That is, at T
OThe time just send picture switching signal S1, next equally every Δ T, promptly in time point T
1, T
2, T
3And T
4The time, also send picture switching signal S1.
Then, as shown in Figure 3, in step S206, when broadcast unit 112 in time point T
O, T
1, T
2, T
3And T
4When receiving picture switching signal S1, switch this a little pictures.For example, in time point T
OThe time, broadcast unit 112 is play the black picture; In time point T
1The time, broadcast unit 112 switches to and plays white picture; In time point T
2The time, broadcast unit 112 switches to and plays red picture; In time point T
3The time, broadcast unit 112 switches to and plays green picture; In time point T
4The time, broadcast unit 112 switches to and plays blue picture.
Then, in step S208, color analysis device 116 is analyzed the color data of display 114 shown pictures.For example, at time point T
O～T
1Between, the color data when color analysis device 116 is analyzed displays 114 and shown red picture, for example be red chroma, green chroma, blue chroma, tone, color saturation and brightness one of at least.
Then, in step S210, when second timing unit 118 when receiving picture switching signal S1, in interval time Δ T, send data acquisition signal S2.Preferably, in order to increase the detection reliability, the quantity of sending data acquisition signal S2 is more than at least two, to increase number of samples.Data acquisition signal S2 amount shipped out between the present embodiment in the interval Δ T is to be that example explains with three.
Then, please refer to Fig. 4, it illustrates the color data acquisition sequential chart of the color data detection system of present embodiment.With display 114 in time point T
O～T
1The time to play the black picture be that example explains, in step S212, when data acquisition unit 120 receives three data acquisition signal S2 in regular turn, the color data that acquisition is corresponding, for example tone C1, tone C2 and tone C3.
As shown in Figures 3 and 4, because first timing unit 110 sends picture switching signal S1 simultaneously to the broadcast unit 112 and second timing unit 118.And the broadcast unit 112 and second timing unit 118 be when receiving picture switching signal S1, and broadcast unit 112 switches picture immediately, simultaneously second timing unit 118 immediately control data acquisition unit 120 remove to save the color data of getting color analysis device 104.So, the broadcast of picture is synchronous with the color data that captures corresponding picture.
Then, in step S214, when data acquisition unit 120 captures tone C1, tone C2 and tone C3, send record cell 122 to so that these color datas are recorded in the record cell 122.
Then, please refer to Fig. 5, the color data that its data acquisition unit that illustrates present embodiment is captured and the comparison synoptic diagram of normal data.In step S216, whether judging unit 124 relatively is recorded in normal data and the color data in the record cell 122, unusual to judge color data.For example, judging unit 124 calculates the mean value of tone C1, tone C2 and tone C3, and then the difference of calculating mean value and normal data.Preferably, the normal data in the record cell 122 comprises a tolerance deviation value.So, just can observe display 114 significantly whether display abnormality takes place as long as compare mean value and normal data.That is to say that the automatic detection device 106 of present embodiment also has the function of calculating automatically at color data except the function with automatic pick-up color data, and judge the whether unusual function of display quality of display 114 automatically.
Remaining picture, as the manner of comparison of the acquisition mode of the broadcast mode of white picture, red picture, green picture and blue picture, color data and the color data that captured is that to play the mode of black picture identical with above-mentioned acquisition, just repeats no more at this.
The color data detection system of the disclosed a kind of display of the above embodiment of the present invention and use its color data detection method electrically connects by automatic detection device and color analysis device, the color data that is captured with automatic pick-up color analysis device.And after automatic detection device captured color data, automatic detection device was to judge automatically whether color data is normal.So, from display display frame to judging that whether normally display frame all be (do not need artificial judge or operation) of robotization, therefore increased the confidence level of test result.
In sum, though the present invention with the preferred embodiment exposure as above, yet it is not in order to limit the present invention.The persond having ordinary knowledge in the technical field of the present invention, without departing from the spirit and scope of the present invention, when doing various changes that are equal to or replacement.Therefore, protection scope of the present invention is when looking accompanying being as the criterion that the application's claim scope defined.
