Detailed Description

Embodiments of the present disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present disclosure and are not to be construed as limiting the present disclosure. On the contrary, the embodiments of the disclosure include all alternatives, modifications, and equivalents as may be included within the spirit and scope of the appended claims.

As shown in fig. 1, in a related embodiment, the screen driving module includes a screen driving circuit and a touch test circuit, the screen driving circuit is connected to an operable area (ACTIVE AREA, AA) of the screen, the screen driving circuit is used for driving the operable area to display an image, the touch test circuit includes a plurality of test modules S1, the test modules S1 include a test point S11 and a plurality of test units S12, the test units S12 include a switch S121 and a touch sensor (Touch Panel sensor) S122, a first end of the switch S121 is connected to the test point S11, and a second end of the switch S121 is connected to the touch sensor S122. The plurality of touch sensors S122 are respectively disposed in the operable areas, the screen driving circuit, the test point S11 and the switch S121 are respectively disposed on the border area of the screen, and the test point S11 and the switch S121 are disposed between the screen driving circuit and the border area.

When the switch S121 is turned on, the path between the test point S11 and the touch sensor S122 is turned on, so that signal transmission can be performed by using the test point S11 and the touch sensor S122 to realize touch test.

Meanwhile, by arranging the test point S11 and the switch S121 between the screen driving circuit and the frame area, the test point S11 and the switch S121 are prevented from occupying extra space on the frame area, so that the influence of the touch control test circuit on the size of the frame area is reduced.

Based on this, the area occupied by the test point S11 and the switch S121 on the frame area is required to be smaller than the area occupied by the screen driving circuit on the frame area, but in the touch control test circuit, each test point S11 corresponds to a plurality of switches S121, and each switch S121 corresponds to one touch sensor S122, so that the number of the test points S11 and the switches S121 is larger, the occupied area of the touch control test circuit is larger, the cost is higher, and the miniaturization design requirement of the screen driving circuit is difficult to meet.

To solve the above-mentioned problems, as shown in fig. 2, an embodiment of the disclosure provides a screen driving module, which includes a screen driving circuit 3 and a touch test circuit, wherein the screen driving circuit 3 is connected to an operable area 21 of a screen 2, the screen driving circuit 3 is used for driving the operable area 21 to display images, the touch test circuit includes a plurality of test modules 1, the test modules 1 include a test point 11 and a plurality of test units 12, the test units 12 include a switch 121 and a plurality of touch sensors 122, a first end of the switch 121 is connected to the test point 11, a second end of the switch 121 is connected to the plurality of touch sensors 122, wherein the plurality of touch sensors 122 are respectively disposed in the operable area 21, the screen driving circuit 3, the test point 11 and the switch 121 are respectively disposed on a border area 22 of the screen 2, and the test point 11 and the switch 121 are located between the screen driving circuit 3 and the border area 22.

It can be understood that the screen driving circuit 3 transmits a driving signal to the operable area 21 to realize the image display of the operable area 21, thereby meeting the use requirement of the screen 2, and meanwhile, when the switch 121 is turned on, the paths between the test point 11 and the plurality of touch sensors 122 are conducted, so that the signal transmission can be performed by using the test point 11 and the plurality of touch sensors 122, and further, the touch test of the screen 2 is realized.

Since the test point 11 and the switch 121 are located between the screen driving circuit 3 and the bezel area 22, the test point 11 and the switch 121 can occupy no other space on the bezel area 22, so that the size influence of the touch control test circuit on the bezel area 22 is reduced.

Moreover, since each test point 11 corresponds to a plurality of switches 121 and each switch 121 corresponds to a plurality of touch sensors 122, the number of the test points 11 and the switches 121 is reduced in multiple, so that the occupied area of the touch test circuit is effectively reduced while the touch test is realized, the cost of the touch test circuit is reduced, and the miniaturization design requirement of the screen driving circuit 3 is met.

Meanwhile, each switch 121 corresponds to a plurality of touch sensors 122, so that a plurality of touch points can be tested simultaneously by using one switch 121 during touch testing, thereby effectively shortening the time of touch testing and improving the efficiency of touch testing.

It should be noted that, the screen 2 includes an operable area 21 and a border area 22, the operable area 21 refers to an operable area on the screen 2, the border area 22 refers to an inoperable border area on the screen 2, and the position of the border area 22 relative to the operable area 21 may be set according to actual needs, which is not limited.

The screen driving Circuit 3 is used to drive the operable area 21 to display an image, the specific type of the screen driving Circuit 3 may be set according to actual needs, and this is not limited thereto, and the screen driving Circuit 3 may be an integration of a Touch panel integrated Circuit (TP IC) and a display driver integrated Circuit (DISPLAY DRIVER INTEGRATED Circuit, TP IC), that is, a Touch and display driver integrated Circuit (Touch AND DISPLAY DRIVER Integration Integrated Circuit, TDDIIC), the screen driving Circuit 3 may employ a Single (Single) random access memory (Random Access Memory, RAM), and the screen driving Circuit 3 employing the Single random access memory may have a smaller longitudinal dimension, which may facilitate a miniaturized design of the screen while reducing the screen cost, wherein the longitudinal dimension of the screen driving Circuit 3 of the Single random access memory may be 1200um.

The number of the touch sensors 122 may be determined according to the number of the touch points, the number of the switches 121 may be determined according to the number of the touch sensors 122, and the number of the test points 11 may be determined according to the number of the switches 121, which is not limited, and if one test point 11 is provided, the number of the switches 121 is four, eight touch sensors 122, and eight touch points that can be tested as a whole are exemplified when each test point 11 corresponds to four switches 121 and each switch 121 corresponds to two touch sensors 122; if there are two test points 11, there are eight switches 121, sixteen touch sensors 122, and sixteen touch points that can be tested as a whole.

In the related embodiment, when each test point 11 corresponds to four switches 121, if the number of the test points 11 is two, the number of the switches 121 is eight, the number of the touch sensors 122 is eight, and the number of the touch points that can be tested in the whole is eight, so it can be seen that, compared with the touch test circuit of the related embodiment, the number of the test points 11 and the switches 121 of the touch test circuit of the related embodiment is half of the number of the test points 11 and the switches 121 of the touch test circuit of the related embodiment in the case that the tested touch points are the same.

In the touch test circuit of this embodiment, since one switch 121 is used to test multiple touch points at the same time, when a touch dead point is tested, the position of the touch dead point cannot be accurately determined, so that the position of the touch dead point can be further determined by using the subsequent test.

The test point 11 is used for connecting with a probe of a touch test transmitter, the specific type of the test point 11 may be set according to actual needs, and this is not limited thereto, and the test point 11 may be a pad (pad) and the length of the test point 11 may be 150um, for example.

After the touch test is performed, the touch test circuit is convenient to disconnect the paths among the touch sensors 122 through the conductors 123 by arranging the conductors 123, so that the touch sensors 122 are prevented from being affected in the subsequent use, and the higher performance of the touch sensors 122 is ensured.
