Abstract
The invention discloses a kind of flicker measurer for liquid crystal unit, comprise and be arranged on the main substrate of enclosure and the display panel at top, outer setting has the optic probe be connected with main substrate, described display panel is electrically connected by flexible flat cable with between main substrate, and described optic probe is connected by shielding line with between main substrate.Flicker measurer for liquid crystal unit cost of the present invention is low, and volume is little, is easy to carry; Effective elimination is inconsistent because human factor causes Flicker minimum value discrimination standard, and can realize automatic Flicker and measure and regulate, the Flicker flicker degree recorded is basically identical with human eye improvement of visual effect, greatly raising work efficiency rate.
Description
Technical field
The present invention relates to a kind of liquid crystal module analyzer, especially relate to a kind of flicker measurer for liquid crystal unit.
Background technology
Liquid crystal module is when display frame, determined by principle of work, always there is Flicker scintillation to a certain degree, and Flicker flicker degree larger time, visual fatigue and other discomfort of people can be caused, so must measure the Flicker flicker degree of every block liquid crystal module before dispatching from the factory, and according to measured value, regulate correlation parameter, make Flicker flicker degree drop to minimum value.
Currently the special Flicker measuring equipment for liquid crystal module is not had because of domestic, the production firm that part is larger, detect in operation at liquid crystal module Flicker, adopt import universal optical equipment, its unit price is expensive, and produce line because need detecting every block module, be in great demand to it, overall device drops into very high; Its volume another is comparatively large, inconvenience carrying, and each machine switches dumb; And communication protocol is underground, Flicker detects numerical value and can only manually read, and cannot send miscellaneous equipment to, carry out Flicker and automatically measure, inefficiency; This kind equipment non-expert is developed for liquid crystal module simultaneously, and its spectral sensitivity range and human eye visual observation effect have different.
And the medium and small production firm of other, because this type of equipment investment cannot be born, employee's visual observation is adopted to determine whether Flicker flicker degree reaches minimum, so just there is employee because of the individual difference such as experience and skill level, same Flicker is differentiated that result is different, causes actual discrimination standard inconsistent.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of a kind of flicker measurer for liquid crystal unit automatically can measuring Flicker flicker angle value.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions.
This flicker measurer for liquid crystal unit, comprise and be arranged on the main substrate of enclosure and the display panel at top, outer setting has the optic probe be connected with main substrate, described display panel is electrically connected by flexible flat cable with between main substrate, and described optic probe is connected by shielding line with between main substrate.
Further, described main substrate is measured acquisition module, Flicker flicker degree DC amount acquisition module and digital display module formed by CPU module, communication module, selector switch module, analog-to-digital conversion module, Flicker flicker degree AC.
Further, described display panel is made up of light emitting diode and LED charactron.
In order to carry out overall degree display to Flicker flicker degree, more further, described light emitting diode quantity is 15, arranges in U-shaped.
In order to accurately show Flicker flicker degree, further, described LED charactron is four.
Compared with prior art, usefulness of the present invention is: this flicker measurer for liquid crystal unit cost is low, and volume is little, is easy to carry; Effective elimination is inconsistent because human factor causes Flicker minimum value discrimination standard, and can realize automatic Flicker and measure and regulate, the Flicker flicker degree recorded is basically identical with human eye improvement of visual effect, greatly raising work efficiency rate.

embodiment:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of flicker measurer for liquid crystal unit shown in Fig. 1, Fig. 2, comprises and is arranged on the main substrate 2 of shell 5 inside and the display panel 1 at top, outer setting have be connected with main substrate 2 have optic probe 3; Described display panel 1 is electrically connected by flexible flat cable with between main substrate 2, realizes the display of real-time Flicker flicker angle value; Described optic probe 3 is connected by shielding line 4 with between main substrate 2, realizes signals collecting; Described display panel 1 is made up of light emitting diode 1-1 and LED charactron 1-2, and wherein light emitting diode totally 15, forms U-shaped curve and carry out overall degree display to Flicker flicker degree, and LED charactron 1-2 is 4, can accurately show Flicker flicker degree.
As shown in Figure 2, described main substrate 2 is measured acquisition module 2-5, Flicker flicker degree DC by CPU module 2-1, communication module 2-2, selector switch module 2-3, analog-to-digital conversion module 2-4, Flicker flicker degree AC and is measured acquisition module 2-6 and digital display module 2-7 and form, and wherein analog-to-digital conversion module 2-4, Flicker flicker degree AC measures acquisition module 2-5, Flicker flicker degree DC and measures acquisition module 2-6 and jointly form complete Flicker flicker degree AC and DC and be separated, gather and preprocessing function.Optic probe 3 realizes changing optical telecommunications and has carried out necessary noise reduction process; Communication module 2-2 can be used for program on-line upgrading, realize in real time and inspection machine carries out linkage function; Digital display module 2-7 is used for display Flicker flicker degree numerical value and AC and DC component in real time.This flicker measurer for liquid crystal unit cost is low, and volume is little, is easy to carry; Effective elimination is inconsistent because human factor causes Flicker minimum value discrimination standard, and can realize automatic Flicker and measure and regulate, the Flicker flicker degree recorded is basically identical with human eye improvement of visual effect, greatly raising work efficiency rate.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
