Specific embodiment
As described above, the inventive system comprises the structures of pointolite array display device, herein will by attached drawing into
Row description, attached drawing are not necessarily drawn to scale.
Following disclosure provides a variety of different embodiments of different characteristic used to implement the present disclosure.Component explained below
Specific embodiment with arrangement is to simplify the disclosure.Certainly, these are only embodiments and are not intended to be limited to the present invention.For example,
In the following description, using " ... under ", " ... below ", the spatial terminologies such as " below ", " above ", to be easy
The positional relationship for describing a component and another component shown in the drawings, in addition to orientation shown in figure, spatial relationship
Term by include using or operation in device a variety of different orientation.Device can be positioned in other ways, such as be rotated
90 degree or in other orientation, and explained accordingly by spatial relation description as used herein symbol.
Due to the otherness of preceding road film manufacturing process and the welding of subsequent end pole and line process between different LED naked cores
Otherness is placed between the point light source naked core on each matrix pixel point of display, and photoelectricity consistency certainly exists significantly
Difference, therefore corresponding optical characteristics and electric current-luminosity curve are also completely different.Believe as a result, according to more unified driving
Number corresponding gray scale that should be shown, can generate the gray scale of whole display and the defect of coloration.
In order to correct to disadvantages described above, the embodiment of the present invention provides a kind of correction pointolite array display device periphery
The method for showing drive pulse signal rectifys the periphery display drive pulse signal of each pixel point light source light-emitting unit
Just.Wherein, pointolite array display device has the pixel in array setting, each pixel is correspondingly arranged a pixel
Light source luminescent unit.
This method comprises:
Determine that the periphery display drive pulse signal inputs optical signal caused by the pixel point light source light-emitting unit
With the difference between expected optical signal, under the expected optical signal, the pixel point light source light-emitting unit it is luminous meet it is aobvious
Show requirement；
Photoelectricity driving data is pre-seted according to difference generation, is input to the pixel point light source light-emitting unit, so that
Optical signal after correction is close to or up to expected optical signal.Under expected optical signal, pixel point light source light-emitting unit is shown
Gray scale and coloration are met the requirements, and are not in defect, in practice, can after correcting to periphery display drive pulse signal
So that the optical signal after correction is compared without being more nearly expected optical signal before correction, ideally, expection can achieve
Optical signal.
Wherein, when being corrected, for each pixel point light source light-emitting unit periphery display drive pulse signal into
Row correction is corrected one by one, can solve the gray scale of whole display and the defect of coloration in this way.
In one embodiment, the step of determining the difference may include:
