It should be noted that the main display area 5 is a front display area, the auxiliary display area 6 is a side display area, and the auxiliary display area 6 may be used for displaying a complete picture together with the main display area 5, or for displaying auxiliary information such as remaining battery capacity, date, time, and prompt information separately.
In the prior art, the sub-pixels in the main display area and the auxiliary display area are driven by the same display driving chip, for example, when the sub-pixels in the main display area and the auxiliary display area need to be driven to display luminance L, the sub-pixels in the main display area and the auxiliary display area all emit light under the action of the same data signal, so that the display effects of the main display area and the auxiliary display area are the same, but the luminance of the sub-pixels in the auxiliary display area, which is actually sensed by human eyes, is lower than L under the influence of the viewing angle color shift factor, so that the display difference exists between the auxiliary display area and the main display area under visual observation. In the display device provided in the embodiment of the present invention, the display driving chip 7 includes two independent chips, namely, the main display driving chip 8 and the auxiliary display driving chip 9, so that the auxiliary display driving chip 9 can be used to drive the sub-pixels 4 in the auxiliary display area 6 individually, so as to compensate the light emitting luminance of the sub-pixels 4 in the auxiliary display area 6, specifically, when the main display area 5 and the auxiliary display area 6 are driven to display a picture, the main display driving chip 8 provides the first Data signal to the first type Data line Data1, so that the sub-pixels 4 electrically connected to the first type Data line Data1 display luminance L, and the auxiliary display driving chip 9 provides the second Data signal to the second type Data line Data2, so that the sub-pixels 4 electrically connected to the second type Data line Data2 in the auxiliary display area 6 display luminance L ', L' ≠ L, for example, L 'is higher than L, and further, the difference between the viewing angle and the viewing angle difference between the auxiliary display area 6 and the main display area 5 caused by the color cast factor is compensated by the difference between L' L In addition, the brightness of the auxiliary display area 6 actually sensed by human eyes is the same as that of the main display area 5, so that the display difference between the main display area 5 and the auxiliary display area 6 under visual observation is improved, the optimization of the curved-surface screen visual effect is realized, and the viewing experience of a user is improved.
In addition, the main display driving chip 8 is used for supplying other control signals, for example, a frame start signal, a clock control signal, and the like for driving the gate driving circuit, in addition to the first Data signal to the first type Data line Data 1.
Optionally, referring to fig. 1, as shown in fig. 3, fig. 3 is a schematic diagram illustrating a connection between a first type of data line and a second type of data line according to an embodiment of the present invention, where the auxiliary display area 6 includes a first auxiliary display area 10 and a second auxiliary display area 11, the non-display area 3 includes a first non-display area 12 and a second non-display area 13, and the first non-display area 12, the first auxiliary display area 10, the main display area 5, the second auxiliary display area 11, and the second non-display area 13 are arranged along a first direction, that is, the second non-display area 13 is a lower step area of the display device; the auxiliary display driving chip 9 is disposed in the first non-display area 12, and the main display driving chip 8 is disposed in the second non-display area 13. Compare in also setting up in second non-display area 13 with assisting display driver chip 9, make and assist display driver chip 9 and main display driver chip 8 to be located first non-display area 12 and second non-display area 13 respectively, can avoid assisting display driver chip 9 occupation space in second non-display area 13, and then avoid display device's lower frame width too big, be favorable to realizing display device's narrow frame design.

With this arrangement, the main display driving chip 8 only provides the first data signal to the sub-pixels 4 in the main display area 5, and does not provide the first data signal to the sub-pixels 4 in the auxiliary display area 6, and all the sub-pixels 4 in the auxiliary display area 6 can compensate the brightness difference caused by the viewing angle color shift factor under the action of the second data signal, so as to further improve the brightness difference between the auxiliary display area 6 and the main display area 5 under the human eye recognition.
Alternatively, as shown in fig. 4, fig. 4 is another connection schematic diagram of the first type Data line and the second type Data line provided in the embodiment of the present invention, the first type Data line Data1 is electrically connected to the sub-pixels 4 of the main display area 5 and the second auxiliary display area 11, and the second type Data line Data2 is electrically connected to the sub-pixels 4 of the first auxiliary display area 10. Because the second non-display area 13 is located on the side of the second auxiliary display area 11 opposite to the main display area 5, if the sub-pixels 4 of the main display area 5 and the sub-pixels 4 of the second auxiliary display area 11 are electrically connected to different Data lines Data, the Data lines Data electrically connected to the sub-pixels 4 of the main display area 5 need to extend to the second non-display area 13 through the second auxiliary display area 11, which results in a larger number of Data lines Data of the second auxiliary display area 11, and further results in a larger coupling between the routing lines, thereby affecting the display effect. The first-type Data lines Data1 are electrically connected with the sub-pixels 4 in the main display area 5 and the second auxiliary display area 11, and the sub-pixels 4 in the same column in the main display area 5 and the second auxiliary display area 11 only need to correspond to one first-type Data line Data1, so that the problem of excessive Data lines Data in the second auxiliary display area 11 is solved.

Further, referring to fig. 3 and 4 again, the third auxiliary display area 14 includes a first auxiliary sub-display area 15 and a second auxiliary sub-display area 16 located at opposite sides of the main display area 5, and the first auxiliary sub-display area 15 and the second auxiliary sub-display area 16 are symmetrically disposed at two sides of the main display area 5, so that the screen occupation ratio is increased, and the appearance design of the display device can be optimized.
Alternatively, as shown in fig. 5, fig. 5 is another expanded schematic view of a main display area and an auxiliary display area in a display device provided in the embodiment of the present invention, where the auxiliary display area 6 includes only a first auxiliary display area 10 and a third auxiliary display area 14, the non-display area 3 includes a first non-display area 12 and a second non-display area 13, the first non-display area 12, the first auxiliary display area 10, the main display area 5, and the second non-display area 13 are arranged along a first direction, the third auxiliary display area 14 and the main display area 5 are arranged along a second direction, and the first direction intersects the second direction; the auxiliary display driving chip 9 is arranged in the first non-display area 12, and the main display driving chip 8 is arranged in the second non-display area 13; the first type Data line Data1 is electrically connected only to the sub-pixels 4 in the main display area 5, and the second type Data line Data2 is electrically connected to the sub-pixels 4 of the first auxiliary display area 10 and the third auxiliary display area 14, respectively.
With this arrangement, the first non-display area 12 is directly located on the side of the main display area 5 opposite to the first auxiliary display area 10, and when the Data lines Data electrically connected to the sub-pixels 4 in the main display area 5 are electrically connected to the main display driving chip 8 of the first non-display area 12, the Data lines Data do not need to penetrate through other display areas, and thus the display of other areas is not affected. Moreover, the auxiliary display driving chip 9 and the main display driving chip 8 are respectively arranged in the first non-display area 12 and the second non-display area 13, so that the width of the lower frame of the display device can be prevented from being too large, and the narrow frame design of the display device is facilitated.
Further, referring to fig. 5 again, the third auxiliary display area 14 includes a first auxiliary sub-display area 15 and a second auxiliary sub-display area 16 located at opposite sides of the main display area 5, and the first auxiliary sub-display area 15 and the second auxiliary sub-display area 16 are symmetrically disposed at two sides of the main display area 5, so that the screen occupation ratio is improved and the appearance design of the display device is optimized.

It should be noted that the arrangement position of the power driving chip 17 shown in fig. 6 is only a schematic illustration, and usually, the power driving chip 17 may be arranged on a back panel of the display device.
Since the magnitude of the driving current for controlling the sub-pixels 4 to emit light is related to the power signal in addition to the data signal, the auxiliary display driving chip 9 can be used to individually control the power signal on the second type of power signal line PVDD2, so that the brightness of the auxiliary display area 6 can be further adjusted by using the second power signal, and the display difference between the auxiliary display area 6 and the main display area 5 caused by the color shift of the viewing angle can be further improved.
Further, the first-type power signal line PVDD1 may be electrically connected to only the sub-pixels 4 in the main display area 5, or may be electrically connected to the main display area 5 and a part of the sub-display areas 6, such as the sub-pixels 4 in the second sub-display area 11. Referring to fig. 6 again, when the first type of power signal line PVDD1 is electrically connected to only the sub-pixels 4 in the main display area 5, all the sub-pixels 4 in the auxiliary display area 6 can compensate the brightness difference caused by the color shift factor of the viewing angle under the action of the second power signal, so as to further improve the brightness difference between the auxiliary display area 6 and the main display area 5 under the human eye recognition.

Because the number of the sub-pixels 4 required to be driven by the auxiliary display driving chip 9 is far smaller than the number of the sub-pixels 4 required to be driven by the main display driving chip 8, the size of the auxiliary display driving chip 9 does not need to be as large as that of the main display driving chip 8, the width of the frame of the non-display area 3 can be reduced to a certain extent by reducing the width of the auxiliary display driving chip 9, and the narrow frame design of the display device is more favorably realized.
