Specific implementation mode
In order to be explained in greater detail the present invention technology contents, spy lift specific embodiment and coordinate appended by illustrate as
Under, but the following drawings and specific implementation mode are not limitation of the present invention, are had in any technical field usual
Skill, without departing from the spirit and scope of the present invention, when can make some changes and embellishment, therefore the protection model of the present invention
It encloses when subject to those as defined in claim.
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
Organic light emitting display panel generally existing vertical crosstalk, mainly since the voltage on data line is in a frame time
It changes and generates.Pixel in organic light emitting display panel is usually arranged in array, for the pixel in same row,
By same data line input data voltage, when data line becomes the data voltage for each pixel input being connected thereto
When change, the problem of just will produce vertical crosstalk, illustrate below for a typical example, is white when needing picture to be shown
When a black rectangle under color background, the problem of due to vertical crosstalk, it can be shown than week above and below black rectangle
The dark grey of edge margin color can be the display picture that a kind of organic light emitting display panel generates vertical crosstalk with reference chart 1, Fig. 1
Schematic diagram, the signal that the picture that Fig. 1 is shown is inputted are to show a black rectangle (see shadow part in Fig. 1 in white background
10) grey (in such as Fig. 1 dash area 20) more dark than periphery white can be shown above and below black rectangle by dividing, with
In figure for 2 points parallel of A, B, when scanning to pixel column where 2 points of A, B, data line can be same to 2 the input phases of A, B
The signal being displayed in white, but when scanning is to black rectangle, the voltage of the data voltage of A points corresponding data line input increases
(or reduction), and the signal of the corresponding data line input of B points is constant, since the pixel in same row is connected by same data line
It is connected together, therefore, the data voltage that (or reduction) is increased on the corresponding data line of A points generates crosstalk to the pixel of A points, causes
A points are dimmed, and the signal of B points corresponding data line input is constant, therefore will not be had an impact to B points, thus A can slightly secretly in
B.The influence of this vertical crosstalk terminates until the black rectangle end of scan, can be substantially returned to just to the display of A points
Often, but the brightness of human eye perception is average value in certain time, so macroscopic view picture seen by person is exactly A points secretly in B points.
