The method and apparatus for controlling the display of the present invention will be described below in conjunction with a specific implementation environment.

In the related art, the display abnormality caused by the pressing is a relatively passive countermeasure. For example, one of the mainstream solutions is: “The touch panel uses a material with a small deformation coefficient”, which can improve the abnormality of the pressure display to a certain extent, but the touch material with a small deformation coefficient will affect the “force data acquisition”. ", equipped with 3D touch There are many difficulties in the equipment; and this material is costly; and the improvement of the problem is limited. Another solution is: “Increase the gap between the two panels”. The solution improves the problem more limited. With this scheme, the spacing is too large to reduce the display effect and increase the thickness of the whole machine. Design concept.

In the related art, when solving the problem of abnormal screen display caused by pressing, there are limited improvement of the problem, and there are many disadvantages such as "difficult acquisition of force data", "high cost", "reduce display effect", "increased thickness does not conform to design concept", and the like.

Therefore, an embodiment of the present invention provides a method and apparatus for implementing display compensation using a pressure sensor (ie, a method and apparatus for controlling screen display in the above embodiment). In the intelligent terminal, using the pressure sensor, or several pressure modules of 3Dtouch, collect the pressure data of the fixed point, calculate the degree of deformation of the display panel, and then calculate the abnormality of the display, actively adjust the display of the pressure area, make a compensation display, and improve the deformation. The display is abnormal. It should be noted that the pressure sensor in the present invention is only used for illustration, and other sensors or combinations of sensors can also achieve the same or similar technical effects, which will not be described one by one.

In the embodiment of the present invention, pressure data of the display area, such as a pressure position area, different pressure values in the area, and the like are first collected by using a pressure sensor or a pressure module. Secondly, the mapping area touch panel deformation is calculated; again, the mapping area display panel deformation is calculated, and then the details of the display abnormality are calculated; again, the display of the corresponding area is adjusted, and the compensation display is performed to improve the display abnormality caused by the deformation. The integrated software and hardware of the embodiment of the invention can better and better optimize and solve the problem of abnormal pressure display.

9 is a schematic diagram of hardware components of a device for performing display compensation using a pressure sensor according to an embodiment of the present invention. As shown in FIG. 9, the device (corresponding to the terminal 82) includes a touch panel (TP). 92 (i.e., TP panel 92 in Fig. 9), display panel 94, and pressure module 96 (corresponding to acquisition module 22 described above), the device will be described below.

During the operation of the user, active or passive will inevitably exert pressure on the front side of the terminal, and the display panel 94 may be deformed to varying degrees, and the problem of FIG. 10 is likely to occur, and an abnormality is displayed.

In the implementation of the embodiment of the present invention, the pressure module 96 is first used to collect pressure data of the display area, such as a pressure position area, different pressure values in the area, and the like. Next, the mapping area touch panel 92 is calculated to be deformed; again, the mapping area display panel 94 is deformed, and the details of the display abnormality are calculated; again, the display of the corresponding area is adjusted, and the compensation display is performed to improve the display abnormality caused by the deformation. Among them, the pressure sensor used is the pressure module 96, which is a part of the 3Dtouch.

Further, the compensation scheme is specifically shown, and the embodiment is merely illustrated. From the hardware perspective, the pixel matrix corresponding to the stress region is extracted, and then the display adjustment is performed from the software side for each pixel of the pixel matrix. As shown in Figure 11.

FIG. 12 is a flowchart of a method for implementing display compensation using a pressure sensor according to an embodiment of the present invention. As shown in FIG. 12, the flow includes:

Step S1202, force three-dimensional data acquisition.

The pressure module 96 of the 3Dtouch utilized in this embodiment collects pressure detailed data. The example of this embodiment is the most important The data pressure(x,y) is reduced to p(x,y).

Where p is the pressure value;

x and y are the position coordinates of the origin of the geometric center of the two panels.

When a certain operation is performed, the center of the panel is pressed, and the p(x, y) function, that is, the pressure is as shown in FIG.

In step S1204, the TP panel 92 deforms the data.

The transformation of the force data with the TP panel 92 deformation. In relation to the characteristics of the panel material, this embodiment exemplifies a correlation coefficient between the two (force, deformation). This coefficient is still related to the coordinates. Here, the coefficient is defined as λ(x, y) (corresponding to the first correspondence described above). .

Then, deformation-TP(x, y) = λ(x, y) × p(x, y) is simplified to d1(x, y).

Where d1 is the TP deformation value;

p is the pressure value;

λ is the coefficient of deformation and pressure;

Still taking the above pressing action as an example, pressing the center of the panel, the function of d1 (x, y), that is, the case where the TP panel 92 is deformed is as shown in FIG.

In step S1206, the display panel 94 deforms the data.

The deformation of display panel 94 generally has a simple linear relationship with the deformation of TP panel 92. In relation to the characteristics of the display panel material, this embodiment exemplifies a coefficient of deformation of two panels, which is defined as δ (corresponding to the second correspondence described above).

Here we simplify it and assume that the coefficient δ is constant.

Then, deformation-DP(x, y) = δ × d1 (x, y) is reduced to d2 (x, y).

Where d2 is the deformation value of the DP display panel 94

D1 is the deformation value of the TP touch panel 92;

δ is the two-plate deformation correlation coefficient;

Taking the above-described pressing operation as an example, pressing the center of the panel, the d2 (x, y) function (corresponding to the third correspondence described above), that is, the case where the display panel DP 94 is deformed is as shown in FIG.

In step S1208, abnormal data fitting is displayed.

The display panel 94 has a mathematically described relationship with the characteristics of the display panel 94 due to the abnormal display of the deformation. Regardless of the non-active light-emitting liquid crystal display panel or the active-matrix organic light-emitting diode (AMOLED), when the display panel 94 is deformed, the deformation region may be abnormally displayed. If the deformation can be mathematically described, the display exception can also be mathematically described.

For example, in today's most popular liquid crystal display panel, the deformation changes the normal deflection direction of the liquid crystal particles, and this direction has a one-to-one correspondence relationship with the display of the "display pixels" in a tabular form. For another example, in today's rapidly developing AMOLED, the deformation changes the polarization direction of the transparent layer and the light-emitting direction of the sub-light-emitting semiconductor, and these display relationships with the "display pixels" have a one-to-one correspondence relationship in a tabular form.

Optionally, the normal displayed function group when there is no pressure deformation is R(x, y), G(x, y), B(x, y), and the set of data is the original data sent to the display module. It is known.

The function group that is abnormally displayed due to pressure deformation is R'(x, y), G'(x, y), B'(x, y). This set of data is the data experienced by the user and is abnormal. This set of data is mathematically described.

In this embodiment, it is simplified that the deformation between the display module DP 94 and the display data is linear, that is, the coefficient corresponding to the R/G/B display is constant.

R'(x,y)=α×d2(x,y)

G'(x,y)=β×d2(x,y)

B'(x,y)=γ×d2(x,y)

Where R'(x,y), G'(x,y), B'(x,y) are data values that the user experiences to display anomalies.

D2 is a deformation value of the display panel DP;

α, β, γ (corresponding to the fourth correspondence described above) are correlation coefficients between deformation and display values;

In step S1210, abnormality compensation is displayed.

Proceeding to step S1208, the difference between the original display data and the abnormal display data is the compensation value (ie, the current display variation variable described above).

Then,

ΔR(x,y)=R(x,y)-R'(x,y);

ΔG(x,y)=G(x,y)-G'(x,y);

ΔB(x,y)=B(x,y)-B'(x,y);

Where R(x, y), G(x, y), B(x, y) are known data and are the original display values.

R'(x,y), G'(x,y), B'(x,y) are data values of the display anomaly experienced by the user, which are fitted by mathematical calculations.

Taking the above-described pressing operation as an example, pressing the center of the panel, ΔR(x, y), ΔG(x, y), ΔB(x, y) function (corresponding to the above-described correspondence relationship), that is, displaying the compensation value is as shown in the figure. 16 shows a, b, and c.

Specifically, after obtaining the compensation values ΔR(x, y), ΔG(x, y), and ΔB(x, y), active display compensation can be performed.

Optionally, the compensation scheme is displayed, and the embodiment continues to be described in detail. 17 is a flowchart of a method for performing active compensation of press deformation according to an embodiment of the present invention. As shown in FIG. 17, the flow includes:

From the software perspective, the pixel matrix of the anomaly region is calibrated according to the above hardware.

Step S1702, the abnormal region pixel matrix is calibrated. As shown in FIG. 11, those specific pixel points in the pixel matrix corresponding to the display module are affected.

In this embodiment, a 4*4 pixel matrix is taken as an example, as shown in FIG. 18.

Step S1704, for 16 pixel points, pix(x1, y1), pix(x1, y2), pix(x1, y3), pix(x1, y4), pix(x2, y1), pix(x2, y2) , pix(x2, y3), pix(x2, y4), pix(x3, y1), pix(x3, y2), pix(x3, y3), pix(x3, y4), pix(x4, y1), Pix(x4, y2), pix(x4, y3), pix(x4, y4).

According to the above formula, ΔR(x, y), ΔG(x, y), ΔB(x, y), three functions, respectively, obtain color change variables of 16 pixel points.

which is:

The first pixel, ΔR (x1, y1) specific value, ΔG (x1, y1) specific value, ΔB (x1, y1) specific value. Further, the amount of change in the pixel point pix (x1, y1) is obtained.

The second pixel, ΔR(x1, y2) specific value, ΔG(x1, y2) specific value, ΔB(x1, y2) specific value. Further, the amount of change in the pixel point pix (x1, y2) is obtained.

......

The sixteenth pixel point, ΔR (x4, y4) specific value, ΔG (x4, y4) specific value, ΔB (x4, y4) specific value. Further, the amount of change in the pixel point pix (x4, y4) is obtained.

Finally, a 4*4 constant RGB variation matrix is formed.

In step S1706, the default system color value is extracted for 16 pixel points, which is known, and the original system sends the data displayed by the display module.

which is:

The first pixel, the original value of R(x1, y1), the original value of G(x1, y1), and the original value of B(x1, y1).

The second pixel, the original value of R(x1, y2), the original value of G(x1, y2), and the original value of B(x1, y2).

......

Sixteenth pixel, R(x4, y4) original value, G(x4, y4) original value, B(x4, y4) original value.

Finally, a 4*4 constant RGB raw value matrix is formed.

In step S1708, the two matrices are added, and the new matrix is obtained as the improved color display data, and the display data can be improved by using the set of compensation data for display.

Namely: the first pixel, R-new (x1, y1) compensates the final value = R (x1, y1) + ΔR (x1, y1);

G-new(x1, y1) compensates for the final value = G(x1, y1) + ΔG(x1, y1);

B-new(x1, y1) compensates for the final value = B(x1, y1) + ΔB(x1, y1).

The second pixel, R-new(x1, y2) compensates for the final value = R(x1, y2) + ΔR(x1, y2);

G-new(x1, y2) compensation final value = G(x1, y2) + ΔG(x1, y2);

B-new(x1, y2) compensates for the final value = B(x1, y2) + ΔB(x1, y2).

......

16th pixel point, R-new(x4, y4) compensation final value = R(x4, y4) + ΔR(x4, y4);

G-new(x4, y4) compensation final value = G(x4, y4) + ΔG(x4, y4);

B-new(x4, y4) compensates for the final value = B(x4, y4) + ΔB(x4, y4).

Finally, 16 pixels (showing anomalous), get the final value RGB data, and display the final value data to improve the effect.
