All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, a schematic diagram of a display device according to an embodiment of the present invention is shown, and fig. 2 is a cross-sectional view taken along a-a' of fig. 1. The display device provided by the embodiment comprises a display assembly 1 and an ink assembly 2 arranged on the display assembly 1, wherein the display assembly 1 comprises a theoretical display area 1a, the theoretical display area 1a covers an area 2a defined by the ink assembly 2, the theoretical display area 1a of the display assembly 1 comprises a1 st column data line D1 to a z th column data line Dz which extend along a column direction and are arranged along a row direction, and the ink assembly 2 is at least positioned on two sides of the display device in the row direction. The display device further comprises a glass cover plate 3 arranged opposite to the display assembly 1, and the ink assembly 2 is printed on one side surface of the glass cover plate 3 facing the display assembly 1. In other embodiments, the orthographic projections of the theoretical display area 1a and the ink set defined area 2a on the glass cover plate 3 may be selected to overlap each other as shown in fig. 3.

In this embodiment, the display module 1 is a display panel that realizes a display function in a display device, and the display module 1 may be an organic light emitting display panel, or may be a liquid crystal display panel, or may be another type of display panel. The structure of the display panel is not specifically described in this embodiment. The theoretical display area 1a of the display module 1 may be understood as an entire area where pixels are disposed in the display module 1, where the theoretical display area 1a of the display module 1 includes a1 st column data line D1 to a z th column data line Dz extending along a column direction and arranged along a row direction, and it should be noted that no structure such as pixels and pixel routing is disposed outside the theoretical display area 1 a.

In this embodiment, the ink set 2 is printed on the surface of the glass cover plate 3 facing the display unit 1. The optional ink component 2 is a black ink layer, and in other embodiments, the optional ink component is a white ink layer, which is not limited in the present invention. The area 2a defined by the ink assembly 2 is a window area 2a of the display device, and the orthographic projection of the theoretical display area 1a on the glass cover plate 3 covers the area 2a defined by the ink assembly 1, namely the window area 2a is positioned in the theoretical display area 1 a. It can be understood that the window area 2a of the display device is a display area of the terminal where the display device is located, and a user can view information displayed in the display area through the window area 2 a. Obviously, if the ink in the ink set 2 is uneven or protruding, the excess ink may intrude into the window area 2a, so that the edge of the image displayed in the window area 2a is blocked by the ink, resulting in missing the edge of the displayed image.

The optional ink sets 2 are located at least on both sides of the display device in the row direction. The ink assembly 2 may cause the picture to be true during the ink process. In other embodiments, the ink sets may optionally be positioned on both sides of the display device in the column direction.

Based on the structure of the display device, the embodiment of the invention provides a debugging method of the display device. The debugging method provided by this embodiment may be implemented by a debugging apparatus, and the debugging apparatus may be implemented in a software and/or hardware manner, and configured in a debugging device, and is used for performing display debugging before the display apparatus leaves a factory. The debugging equipment adopts a debugging method to determine the initial position and the end position of the transmission data line and the initial position and the end position of the transmission scanning line in the actual display area, so as to modify the transmission data column and the write-in data row of the driving chip, thus the display edge of the display picture of the display device in the display stage has no display loss, and the display effect is improved. The debugging equipment can be selected as independent testing equipment, the display device is placed in the debugging equipment, and the debugging equipment drives a driving chip of the display device according to the following debugging method to realize the display debugging of the display device.

Fig. 4 is a flowchart illustrating a debugging method of a display device according to an embodiment of the present invention. The debugging method of the embodiment includes:

s1, referring to fig. 5, it is determined that the initial test display area 1b in which no display screen is missing is present at the display edges on both sides in the row direction of the display screen, and the initial test display area 1b is formed by the a-th column data line Da to the b-th column data line Db located in the area 2a defined by the ink set 2, 1< a < b < z.

In this embodiment, the debugging device outputs the pre-estimated data line column numbers a1 and b1 that do not cause display screen loss to the display device, and the driving chip of the display device receives the data line column number information a1 and b1 and drives the test display area formed by the data line of the a1 th column to the data line of the b1 th column to display the test screen. Specifically, the driving chip drives the 1 st column data line to the a1-1 th column data line and the b1+1 th column data line to the z th column data line to output black state data, and the driving chip drives the a1 th column data line to the b1 th column data line to output test data, so that a test display area formed by the a1 th column data line to the b1 th column data line displays a test picture.

The image acquisition module of the debugging equipment acquires a display picture of the display device, and the debugging device detects whether display picture loss exists at the display edges of the two sides of the test display area in the row direction. If no display screen is missing, determining that a is a1, b is b1, and a test display area formed by the data line from the a1 th column to the b1 th column is an initial test display area. And if the display picture is missing on at least one side, reselecting the number of the data line rows on the side with the display missing until obtaining an initial test display area with the display picture not missing on the display edges of the two sides of the display picture in the row direction.

The a-th to b-th column data lines Da to Db of the initial test display area 1b refer to the a-th to b-th column data lines Da to Db located in the orthographic projection of the window area 2a in the theoretical display area 1 a. It is understood that the initial test display area 1b is selected as long as the condition that the area 2a defined by the ink set 2 is within the orthographic projection of the theoretical display area 1a and the display screen has no defect is satisfied, and the area of the initial test display area is not further limited. For example, z is 1480, the window area 2a theoretically covers the 101 th column data line to the 1300 th column data line on the orthographic projection of the theoretical display area 1a, and optionally a is 600, b is 800; even in other embodiments, it is possible to select the middle column where a and b are adjacent and the number of columns is close to the theoretical display area, and z 1480, a 739, and b 740.

S2, referring to FIG. 6, selecting the ith test display area formed by the a-i column data line to the b + i column data line in the area defined by the ink assembly, and providing a test picture for the ith test display area, wherein 1 is not less than i.

The selectable providing of the test picture to the ith test display area comprises: applying test frame data signals to the a-i row data line to the b + i row data line to enable the i test display area to display a test frame, and applying black state data signals to the 1 st row data line to the a-i-1 row data line and the b + i +1 row data line to the z row data line.

In this embodiment, the debugging device has determined the number of data line columns a and b and an initial test display area formed by the a-th column data line to the b-th column data line, and then the debugging device changes the number of data line columns to determine a new test display area, which covers the initial test display area. Specifically, the debugging device moves the initial position of the transmission data line to the left, that is, the initial column number of the transmission data line in the new test display area is less than a, and the debugging device moves the end position of the transmission data line to the right, that is, the end column number of the transmission data line in the new test display area is greater than b, wherein the left and right sides are the left and right sides in the column direction. Here, the initial position of the transmission data line refers to a data line row in which the reception of the test data is started in the new test display region, and the end position of the transmission data line refers to a data line row in which the reception of the test data is ended in the new test display region.

The debugging equipment outputs the selected data line column numbers a-1 and b +1 to the display device, and a driving chip of the display device receives the data line column number information and drives a1 st test display area formed by the a-1 st column data line to the b +1 th column data line to display a test picture. Specifically, the driving chip drives the a-1 th column data line to the b +1 th column data line to output a test picture data signal, and drives other data lines to output black data. Where i may be a stepped value, such as i being equal to 1,2,3, … in sequence, resulting in an increasing ith test display area.

An image acquisition module of the debugging device acquires a display picture of the display device, and the debugging device detects whether display picture loss exists at the display edges of the 1 st test display area in the row direction. If the display frame is not lost, the debugging equipment continues to expand the test display area in the row direction, and controls the driving chip to drive the 2 nd test display area formed by the a-2 nd column data line to the b +2 nd column data line to display the test frame and detect the test frame. And repeating the steps until the display edges of the display picture at the two sides in the row direction are detected to start to form a test display area with the display picture missing. The display gray scale of the selectable test picture is more than or equal to 200, so that the image acquisition module can conveniently acquire the display picture with obvious contrast, and further defect detection is easy to carry out.

S3, refer to fig. 7, which detects data line columns m and n corresponding to the display screen of the test display area when the display screen starts to have a display screen missing at both sides in the row direction, where m < n.

Optionally, the steps specifically include: acquiring a display picture of the test display area through an image acquisition module; detecting whether display missing exists at any side display edge of a display picture of the test display area in the row direction; if so, determining the corresponding data line array when the display frame of the test display area has a display frame missing at the display edge in the row direction.

For the left side display edge, if the debugging equipment detects that the display picture of the i-1 th test display area has no display picture missing at the left side display edge in the row direction, the test display area continues to be expanded leftwards and outwards in the row direction, and the driving chip is controlled to drive the i-th test display area which takes the a-i-th column data line as the initial position of the transmission data line to display the test picture and detect the test picture. And if the display frame loss exists at the left display edge of the display frame of the ith test display area, determining that the initial position of the transmission data line of the ith test display area is covered by the ink, namely the data lines of the (a-i) th rows of the theoretical display area are covered by the ink. It is known that there is no missing display frame in the display frame of the i-1 th test display area at the left display edge in the row direction, the a-i th column data line of the theoretical display area is the inflection point of the missing display frame at the left display edge of the display frame, i.e. a-i is determined as the corresponding data line column m when the missing display frame starts to appear at the left display edge of the display frame of the display device.

For the right side display edge, when the debugging equipment detects that the display picture of the j-1 th test display area has no display picture missing at the right side display edge in the row direction, the test display area continues to be expanded towards the right in the row direction, and the driving chip is controlled to drive the j-th test display area which is at the end position of the transmission data line by the b + j-th column data line to display the test picture and detect the test picture. And if the display frame is missing at the right display edge of the display frame of the jth test display area, determining that the end position of the transmission data line of the jth test display area is covered by the ink, namely the data line of the (b + j) th row of the theoretical display area is covered by the ink. It is known that there is no missing display frame at the right display edge of the display frame of the j-1 th test display area in the row direction, the b + j th column data line of the theoretical display area is an inflection point of the missing display frame at the right display edge of the display frame, that is, b + j is determined as the corresponding data line column n when the missing display frame starts to appear at the right display edge of the display frame of the display device.

It will be appreciated that the processing of the data line columns m and n is not independent of each other, but may be performed simultaneously. If m is determined first, the initial position of the transmission data line of each test display area is fixed in the subsequent n determination process until n is determined.

S4, referring to fig. 8, the test display area, which is formed by the data line at the m +1 th column to the data line at the n-1 th column and has no missing display screen at the display edges on both sides in the row direction, is adjusted to the actual display area 1c of the display device, where m < a < b < n < z.

In this embodiment, data line rows m and n corresponding to display frame losses occurring when display frames begin to occur at display edges on both sides of the display frame of the test display area in the row direction are determined, so that there is no display loss at the left display edge of the test display area where the m +1 th row of data lines is used as the start position of the transmission data line, and there is no display loss at the right display edge of the test display area where the n-1 th row of data lines is used as the end position of the transmission data line. The start and end positions of the transmission data line in the driving chip of the display device are modified, and the m +1 th column data line and the n-1 th column data line are respectively determined as the start and end positions of the transmission data line of the display device.

Optionally, the method further includes: in the display stage, black state data signals are applied to the 1 st column data line to the m-th column data line, image data signals are applied to the m +1 th column data line to the n-1 th column data line, and black state data signals are applied to the n-th column data line to the z-th column data line.

In the display stage, the display area formed by the m +1 th row data line to the n-1 th row data line is an actual display area of the display device, and other data lines output black state data, that is, the voltage of the data line covering the uneven rows with ink or the incomplete rows with ink is set to be a black state, so that the display effect is improved. It will be appreciated that the reasons for the lack of display of the display device include uneven ink coverage and incomplete ink coverage of pixels.

In the embodiment, an initial test display area with no display frame missing at the display edges of the display frame on both sides in the row direction is determined, and the starting position and the ending position of a corresponding transmission data line are determined; changing the initial position and the end position of the transmission data line, gradually increasing the test display area, and driving the test display area to display a test picture; detecting data line columns m and n corresponding to display frames of a test display area when the display frames begin to have display frame loss at two side display edges in the row direction; and adjusting the test display area formed by the m +1 th column data line to the n-1 th column data line and having no display screen missing at the display edges at two sides in the row direction to be an actual display area of the display device. Obviously, in the display stage, the actual display area of the display device displays images, and the display edges of the actual display area of the display device in the row direction do not have display frame loss, so that the display effect is improved, and the problem of display information loss caused by uneven or incomplete coverage area of the ink layer is avoided.

Illustratively, based on the above technical solution, the ink set 2 shown in fig. 1 may at least include a first side ink area and a second side ink area, the theoretical display area 1 includes a first side display edge disposed adjacent to the column 1 data line D1 and a second side display edge disposed adjacent to the column z data line Dz, the first side ink area is disposed at least adjacent to the first side display edge, and the second side ink area is disposed at least adjacent to the second side display edge. Wherein the first side ink area and the second side ink area are both side areas of the ink set 2 in the row direction, wherein the first side ink area is located on the left side in the column direction, and the second side ink area is located on the right side in the column direction. The first side display edge and the second side display edge are both side edges of the theoretical display area 1 in the row direction, wherein the first side display edge is located on the left side in the column direction, and the second side display edge is located on the right side in the column direction. Thus, the first side ink area is disposed at least adjacent to the first side display edge and the second side ink area is disposed at least adjacent to the second side display edge, referring to FIG. 1 where the first side ink area of ink set 2 overlies the first side display edge of theoretical display area 1 and the second side ink area of ink set 2 overlies the second side display edge of theoretical display area 1.

Referring to fig. 9, the operation of determining that the display screen has the initial test display region with no display screen missing at the display edges on both sides in the row direction at step S1 includes:

calculating the ratio of the size L1 of the first overlapping area to the size of the theoretical display area 1a in the row direction to determine the number p of data line columns covered by the first overlapping area, and selecting a to be larger than p, wherein the first overlapping area is the overlapping area of the first side ink area and the theoretical display area;

and calculating the ratio of the size L2 of the second overlapping area to the size of the theoretical display area 1a in the row direction to determine the number q of data line columns covered by the second overlapping area, and selecting b to be smaller than z-q, wherein the second overlapping area is the overlapping area of the second side ink area and the theoretical display area.

In this embodiment, the size of the theoretical display area in the row direction is known, the size of the first overlapping area, which is the overlapping area of the first side ink area and the theoretical display area, in the row direction is known, and the number z of data line columns in the row direction of the theoretical display area is known, so that the ratio of the size of the first overlapping area to the size of the theoretical display area in the row direction is equal to the ratio of the number z of data line columns covered by the first overlapping area, so as to determine the number p of data line columns covered by the first overlapping area. A is selected to be greater than p. Similarly, the number q of the data line columns covered by the second overlapping area is determined, and b is selected to be smaller than z-q.

The above is the process of determining the initial test display area in the row direction. In other embodiments, other methods may also be employed. Referring to fig. 10, taking the resolution 1440+ a + b of the theoretical display area in the row direction as an example, the number 1440-a '-b' of data lines covered by the area defined by the ink set is estimated according to the size of the theoretical display area in the row direction and the size of the area defined by the ink set, and the initial position DLs of the transmission data line driven by the driving IC is determined to be in a + a '+1 column and the end position DLe of the transmission data line is determined to be in 1440+ a-b' column; when a picture with white 255 gray scales is transmitted to the test display area, the width of a display picture of the test display area is only 1440-a '-b' in the row direction; changing the position of the data line, gradually moving the initial position of the transmission data line to the left, moving the end position of the transmission data line to the right, moving the frame which sends a test picture to the screen to two sides along with the movement of the data line, and displaying the total column number of DLe-DLs + 1; when the left side frame line and the right side frame line are uneven or cannot display the whole pixel and the color edge phenomenon occurs, recording the initial position DLs1 of the transmission data line which is displayed normally at last as a + a1+1 and the end position DLe1 of the transmission data line as 1440+ a-b 1; and determining the position of the data line, and transmitting a start position DLs1 (a + a1+ 1) of the transmission data line and an end position DLe1 (1440 + a-b 1) of the transmission data line to the IC, wherein the start position of the transmission data line and the end position of the transmission data line transmitted to the screen by the IC are DLs1 and DLe1 respectively, and the column resolution of the screen is 1440-a1-b 1.

In this embodiment, the process of the debugging device determining the initial test display area in the column direction is similar to step S1. That is, the number of rows x1 and y1 of scan lines without missing display frames can be estimated in advance, and then the driving chip of the display device is controlled to provide test frames for the test display area formed by the scan lines from the x1 th row to the y1 th row. When scanning lines from 1 st to x1-1 st rows, each data line outputs a black data signal; when scanning lines of the x1 th row to the y1 th row, each data line outputs a test picture data signal; when scanning lines from the y1+1 th row to the w th row, each data line outputs a black data signal, and the test display area displays a test picture.

The specific procedure is similar to step S2. It should be noted that, in the line scanning process, the display device still scans from the first line to the last line, and only when scanning lines outside the test display area, the data lines output black data, and when scanning lines inside the test display area, the data lines output test frame data.

The initial line number of the transmission scanning lines of the new test display area is less than x, and the end line number of the transmission scanning lines is greater than y, wherein the initial position of the transmission scanning lines refers to the scanning line row of the new test display area, which starts to receive the test data, and the end position of the transmission scanning lines refers to the scanning line row of the new test display area, which ends to receive the test data. Where j may be a stepped value, such as j being equal to 1,2,3, … in sequence, resulting in a sequentially increasing jth test display area.

The debugging equipment controls a driving chip of the display device to provide a test picture for the jth test display area, an image acquisition module of the debugging equipment acquires the display picture of the display device, and the debugging device detects whether display picture loss exists on the display edges of the display picture of the jth test display area in the column direction or not. And if the display picture is not lost, the debugging equipment continues to expand the test display area in the column direction.

Then, the start position and the end position of the transmission scanning line in the driving chip of the display device are modified, wherein the start position of the transmission scanning line refers to the start row of the image data output by the data line, the end position of the transmission scanning line refers to the end row of the image data output by the data line, and the data line always outputs black state data when the other scanning lines are at positions.

In this embodiment, the scanning mode of the driver chip is unchanged, and only the start line position and the end line position of the output image data are modified, so that there is no display frame missing at the display edges of the actual display area in the column direction, that is, the data line voltage of the ink covering uneven sliding or the ink covering incomplete rows of pixels is set to be a black state, thereby improving the display effect.

Alternatively, referring to the example of fig. 13, which shows the resolution 2880+ a + B of the theoretical display area in the column direction, the number of scan lines 2880-a '-B' covered by the area defined by the ink set is estimated according to the size of the theoretical display area in the column direction and the size of the area defined by the ink set, and the initial position HLs of the transfer scan line and the end position HLe of the transfer scan line driven by the driving IC are determined, which is similar to the embodiment described in fig. 10.

Specifically, the resolution is estimated first, and if the number of rows of scanning lines on the upper side of the theoretical display area covered by the area defined by the ink set is estimated to be a + a ', the initial position HLs of the transmission scanning line is a + a' +1 row; the number of scan lines on the underside of the theoretical display area covered by the area defined by the ink set is estimated to be a-B 'lines, and the end of transfer scan line position HLe is 2880+ a-B' lines.
