Description
Technical field
The present invention relates to a kind of is by producing the method and system that line calibration makes mobile phone obtain consistent light effects.Belong to tactile
Touch the light sensation calibration field of screen mobile phone.
Background technology
Existing touch-screen mobile phone light sensation is calibrated, and usually chooses several machines (touch-screen mobile phone produced), for
IR hole (perforate at light sensation) the ink light transmittance curve of the TP (touch screen) of these several machines, and the characteristic of producer's light sensation,
Provide one group of calibration parameter, after batch production, this is processed the most again.
The IR hole ink light transmittance of TP controls general ± 5%, in order to hide light sensitive device, meets the demand of ID, IR hole
Visible ray ink light transmittance needs below 10%.Cellular telephone companies is generally higher to light transmittance coherence request, it is seen that light is saturating
Light rate standard is 6% ± 4%, but thus can there is a problem in that the TP of visible light transmittance rate 2% and 10%, is given to light sensation
Light difference have 5 times, even if genuine number of samples is a lot, the calculating parameter be given is accurate, is also average according to light transmittance
It is worth to final parameter, brings this thing of error to evade the TP of limit on the upper side and limit light transmittance on the lower side to light sensation result.
The light transmittance curve shape of every kind of ink is basically identical, and being because ink can the most slowly precipitate, so after
The IR hole ink of face brush can be more slightly lower than light transmittance before, and the producer of brush ink can add diluent stirring after a while,
But so can affect production efficiency, so light transmittance can only control in certain scope.
