Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making all other embodiment that obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
For the advantage that makes technical scheme of the present invention is clearer, the present invention is elaborated below in conjunction with accompanying drawing and embodiment.
According to the definition of ISO, the liquid crystal display response time has only been considered the extreme time of switching of the shortest pixel Hei-Bai-Hei of time spent, and when weighing actual the use, occurring does not have too many guiding value when maximum GTGs switches.The whole response time of pixel has only accounted for that whole pixel rises and time of 80% of decline process, and so-called white refers to 10% gray scale, and black refers to 90% gray scale, and all the other times of 20% have been left in the basket.Because for liquid crystal molecule, power up starting and to stablize these two stages at last be time-consuming, the process that the gray scale at two 20% transforms might surpass the defined response time of ISO, so ISO is this saves 20% definition and just can beautify index greatly.When simultaneously color change has been ignored in the definition of ISO, different gray scales time of switching just.From the displaying principle of liquid crystal, when pixel when being converted into than dark gray than the light gray degree, be added in the also corresponding reinforcement of voltage of pixel two end electrodes.But compare with the maximum excitation voltage that the Hei-Bai that defines in the ISO standard-Hei switches, it is much lower when gray scale is switched, to apply voltage accordingly, and therefore the speed of liquid crystal molecule counter-rotating response also can be slack-off in this case.In like manner, when color range was converted into than the light gray rank from more dark-grey rank, process was opposite, but the corresponding electrode voltage of light GTG this moment is also non-vanishing, and correspondent voltage difference arousal effect also can variation, and the negative edge time also can be elongated.
The liquid crystal display of 120Hz can receive the image of 120Hz, and its response time is shorter than the response time of 100Hz liquid crystal display in theory.But; The response time that some liquid crystal display marked not is the used time of Hei-Bai-Hei on the practical significance; And be rise time or fall time; Possibly be " GTG " also, it is short to cause response time of these so-called 120Hz liquid crystal displays not have response time of 100Hz liquid crystal display.Therefore, just confirm that with reference to the instructions of liquid crystal display its response time is insecure, have only through actual measurement and could confirm exactly whether these liquid crystal displays satisfy the requirement of the 3D liquid crystal display of 100Hz.
Embodiment one
Present embodiment provides a kind of liquid crystal display response time measuring method, and is as shown in Figure 1, and said method comprises:
101, on liquid crystal display, show the 3D rendering that presets graph card, wherein as shown in Figure 2, a said side that presets graph card is the strip black region, and all the other places are white portion, and the area of said black region is no more than said the half the of graph card area that preset.
Particularly, be example with the 3D state of 100Hz, said preset graph card and be divided into about two width of cloth images, as shown in Figure 3, what left eye was seen is the image that the left side has black region; As shown in Figure 4, what right eye was seen is the pure white image on the right; It in frequency the demonstration that images displayed replaces for left and right sides image under the 3D state of 100Hz; Image occurs respectively 50 times about p.s.; As shown in Figure 5, the said 3D rendering that presets graph card that finally obtains comprises that said black region and said white portion show with the same frequency stack and the gray area that forms (among the figure with trellis box indicating).
102, adopt photoelectric probe that the lightness of the liquid crystal display that shows the said 3D rendering that presets graph card is detected.
Particularly, adopt photoelectric probe that the lightness of the liquid crystal display that shows said gray area is detected.
103, the lightness curve over time that shows the liquid crystal display of the said 3D rendering that presets graph card through oscillograph output.
Particularly, the lightness curve over time that shows the liquid crystal display of said gray area through oscillograph output.
104, confirm rising edge time and the negative edge time of said change curve in one-period.
Wherein, the said rising edge time is said curve is risen to peak by minimum point in one-period 90% used time;
The said negative edge time is said curve is dropped to peak by peak in one-period 10% used time.
105,, obtain the response time of said liquid crystal display with said rising edge time and the addition of negative edge time.
As shown in Figure 6, be the lightness of the 3D rendering of the 100Hz that presets graph card that liquid crystal display showed of 120Hz curve over time, wherein, two dotted lines are represented maximum brightness and minimum brightness respectively up and down.With 90% of peak brightness is the rising edge time that intercept point obtains to be about 4.16ms, is that the negative edge that intercept point obtains is about 7ms with 10% of peak brightness, and then the response time of said liquid crystal display is 4.16ms+7ms=11.16ms.
Hence one can see that, and said liquid crystal display can reach minimum brightness and maximum brightness in 10ms, under certain backlight control, can realize the 3D Presentation Function through image compensation, and the workload of image compensation is little.
Adopt the above method, owing to preset graph card self-control, just by means of photoelectric probe and oscillograph, can measure the response time of liquid crystal display, so that select to be fit to do the liquid crystal display of the 3D TV of 100Hz, metering system is simple and cost is lower.
