Abstract
The invention discloses a flicker measurer for a liquid crystal unit. The flicker measurer comprises a main substrate arranged in a shell and a display panel arranged on the top, wherein an optical probe connected with the main substrate is arranged outside the flicker measurer; the display panel is electrically connected with the main substrate through a flexible flat cable; and the optical probe is connected with the main substrate through a shielding line. The flicker measurer for the liquid crystal unit is low in cost, has a small volume, and is portable; the inconsistency of Flicker minimum value judgment standards caused by manmade factors can be eliminated effectively; the Flicker can be measured and adjusted automatically; the measured Flicker is substantially consistent with an eye visual effect; therefore, the work efficiency is improved greatly.
Description
Technical field
The present invention relates to a kind of liquid crystal module analyzer, especially relate to a kind of liquid crystal module Flicker flicker degree analyzer.
Background technology
By the principle of work decision, always there is Flicker scintillation to a certain degree in liquid crystal module when display frame; And Flicker flicker degree is when big; Can cause people's visual fatigue and other discomfort, thus before dispatching from the factory, must measure the Flicker flicker degree of every liquid crystal module, and according to measured value; Regulate correlation parameter, make Flicker flicker degree drop to minimum value.
Because of the domestic current Flicker measuring equipment that does not have to be directed against specially liquid crystal module; The production firm that part is larger is detected in the operation at liquid crystal module Flicker, adopts import universal optical equipment; Its unit price is expensive; Every module is detected because of need and produce line, it is in great demand, the overall device input is very high; Its volume is bigger in addition, the inconvenience carrying, and each machine switches dumb; And communication protocol is underground, and Flicker detects numerical value and can only manual work read, and can't send miscellaneous equipment to, carries out Flicker and measures inefficiency automatically; This kind equipment is non-simultaneously develops to liquid crystal module specially, and its spectrum sensitive scope and human eye visual observation effect have certain difference.
And the medium and small production firm of other; Because of bearing this kind equipment input; Adopt employee's visual observation to confirm whether Flicker flicker degree reaches minimum; So just exist the employee because of individual differences such as experience and skill levels, it is different that same Flicker is differentiated the result, causes actual discrimination standard inconsistent.
Summary of the invention
Technical matters to be solved by this invention provides a kind of a kind of liquid crystal module Flicker flicker degree analyzer that can measure Flicker flicker degree value automatically.
In order to solve the problems of the technologies described above, the present invention realizes through following technical scheme.
This liquid crystal module Flicker flicker degree analyzer; Comprise the main substrate that is arranged on enclosure and the display panel at top; Outer setting has the optic probe that is connected with main substrate; Be electrically connected through flexible flat cable between said display panel and the main substrate, be connected through shielding line between said optic probe and the main substrate.
Further, said main substrate is made up of CPU module, communication module, SS module, analog-to-digital conversion module, Flicker flicker degree AC amount acquisition module, Flicker flicker degree DC amount acquisition module and digital display module.
Further, said display panel is made up of light emitting diode and LED charactron.
Show that in order Flicker flicker degree to be carried out overall degree more further, said light emitting diode quantity is 15, be the U font and arrange.
In order accurately to show Flicker flicker degree, further, said LED charactron is four.
Compared with prior art, usefulness of the present invention is: this liquid crystal module Flicker flicker degree analyzer cost is low, and volume is little, is easy to carry; Effectively eliminate because of human factor causes inconsistent to Flicker minimum value discrimination standard, can realize that automatic Flicker measures and regulates, the visual effect basically identical of Flicker flicker degree that records and human eye improves the work efficiency rate greatly.
