In order to make the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. It will be apparent that the described embodiments are some, but not all, embodiments of the invention. And embodiments of the invention and features of the embodiments may be combined with each other without conflict. All other embodiments, which can be made by a person skilled in the art without creative efforts, based on the described embodiments of the present invention fall within the protection scope of the present invention.
In the prior art, for a flexible OLED (Organic Electroluminesence Display, i.e., organic light emitting semiconductor) display screen, PCD (Panel Crack Detect, i.e., screen Crack detection) metal traces are often used to detect whether a Crack exists at the edge of the flexible OLED display screen (i.e., break), specifically, the PCD metal trace is disposed around the screen for one circle, one end of the PCD metal trace is connected with a G pixel (i.e., a green pixel), the other end of the PCD metal trace is connected with a test signal, if the Crack occurs at the edge of the screen, the PCD metal trace is broken, resulting in a broken signal line on the G pixel, and an OPEN (i.e., broken) state occurs, so that a specific black G bright line appears, and the flexible OLED display screen is determined to be bad. It can be seen that the whole process is less efficient in detecting the Crack and the position of the Crack cannot be precisely located.
In view of the above, the embodiment of the invention provides a flexible display screen, which is used for detecting whether the edge of the flexible display screen is broken or not and positioning the position of the broken edge.
Specifically, as shown in fig. 1, one of the flexible display screens provided in the embodiment of the present invention is schematically shown, and specifically, is divided into a display area a and a non-display area B surrounding the display area a; the display area a includes data lines and gate lines 1 arranged to cross, and the non-display area B includes peripheral driving circuits 10 respectively arranged at both sides of each gate line 1, and a test circuit 20 electrically connected to the peripheral driving circuits 10; as shown in fig. 1, the direction indicated by the arrow X is the data line extending direction, and the direction indicated by the arrow Y is the gate line 1 extending direction.
The peripheral driving circuit 10 includes two sets of cascaded shift registers 30 (i.e., EOA shown in fig. 1), one shift register 30 is electrically connected to one gate line 1, the test circuit 20 includes a plurality of test switches 201 and a plurality of test lines 202, one test switch 201 is electrically connected to one shift register 30, the test lines 202 are connected to the test switches 201 in a one-to-one correspondence, the test lines 202 are at least disposed at an outer edge of the non-display area B and have line segments consistent with an extending direction of the data lines, and the test circuit 20 is configured to load signals to the electrically connected shift registers 30 when the connected test lines 202 break, so that the corresponding gate lines 1 load lighting signals. The number of shift registers 30 in the flexible display panel shown in fig. 1 is 4, each shift register 30 is electrically connected to one gate line 2, and each shift register 30 is electrically connected to one test switch 201. In addition, the test lines 202 are connected to the test switches 201 in a one-to-one correspondence, and the test lines 202 are disposed at least at the outer edges of the non-display area and have line segments in the same direction as the extending direction of the data lines. The test line 202 is a portion of a line segment that is consistent along the extending direction of the data line, where "consistent" refers to substantially consistent, not absolutely consistent. The test lines 202 may be disposed entirely on the outer edge of the non-display area, or may be partially disposed on the outer edge of the non-display area, which is not limited herein. In the implementation process, once any test line 202 is broken, the test circuit 20 connected with the test line loads signals to the shift register 30 electrically connected with the test line, so that the corresponding grid line loads a lighting signal, and the position of the non-display area corresponding to the grid line 2 is the position where the break of the flexible display screen occurs, thus, the break of the flexible display screen is confirmed and the break is positioned.
In an embodiment of the present invention, as shown in another structural schematic diagram of the flexible display screen in fig. 2, specifically, the test switch 201 includes a thin film transistor, where a source electrode and a gate electrode of the thin film transistor are electrically connected to different ends of the test line 202, so that the thin film transistor is electrically connected to the test line 202, a drain electrode of the thin film transistor is electrically connected to the shift register 30, so that the thin film transistor is electrically connected to the shift register 30, and a source electrode of the thin film transistor is electrically connected to the power signal line 2, so that the control of the switching state of the thin film transistor can be realized by adjusting the potential of the power signal line 2, and further detection of the breaking condition of the test line 202 is realized.
In the embodiment of the present invention, the thin film transistor may be an N-type thin film transistor, or may be a P-type thin film transistor, specifically, the test switch 201 is an N-type thin film transistor, and the power signal line 2 provides a low potential signal; fig. 3 and fig. 4 are schematic diagrams of one of the circuit structures included in the region C in fig. 2, for example, when the potential of the low potential signal VGL is-7V and the threshold voltage Vth of the N-type thin film transistor is 2V, if the gate voltage vg= -7V, the source voltage vs= -7V, and the gate-source voltage vgs=vg-vs=0v of the N-type thin film transistor are at the same time, VGs is smaller than Vth, the N-type thin film transistor is in the off state, which indicates that the edge of the flexible display screen where the test line 202 is located is not broken, and one of the circuit structures included in the region C in fig. 2 is shown in fig. 3. Assuming that the edge of the flexible display screen where the test line 202 is located is broken, at this time, vg=0v, vgs=vg-vs=0v- (-7v) =7v, at this time, VGs is greater than Vth, the N-type thin film transistor is in an on state, at this time, a bright line will be generated in the display area corresponding to the test line 202, at this time, one of the circuit structures included in the region C in fig. 2 is schematically shown in fig. 4. In the implementation process, in the initial state, a cut-off signal can be loaded on the N-type thin film transistor, and once it is determined that a bright line exists on the flexible display screen, the position of the test line 202 corresponding to the grid line 2 where the bright line exists can be determined to be broken according to the position of the bright line.
In the embodiment of the present invention, the test switch 201 is a P-type thin film transistor, and the power signal line provides a high potential signal. Fig. 5 and fig. 6 are schematic diagrams of one of the circuit structures included in the region C in fig. 2, for example, when the potential of the high potential signal VGH is 7V and the threshold voltage Vth of the P-type thin film transistor is-2V, if the gate voltage vg=7v, the source voltage vs=7v, and the gate-source voltage vgs=vg-vs=0v of the P-type thin film transistor are at the same time, and VGs is greater than Vth, the P-type thin film transistor is in the off state, which indicates that the edge of the flexible display screen where the test line 202 is located is not broken. At this time, a schematic diagram of one of the circuit structures included in the region C in fig. 2 is shown in fig. 5. Assuming that the edge of the flexible display screen where the test line 202 is located is broken, at this time, vg=0v, vgs=vg-vs=0v-7v= -7v, at this time, VGs is smaller than Vth, the P-type thin film transistor is in an on state, at this time, a bright line will be generated in the display area corresponding to the test line 202, at this time, one of the circuit structures included in the region 1 in fig. 2 is schematically shown in fig. 6. In the implementation process, in the initial state, a turn-off signal can be loaded on the P-type thin film transistor, and once it is determined that a bright line exists on the flexible display screen, the position of the test line 202 corresponding to the grid line 1 where the bright line appears can be determined to be broken according to the position of the bright line.

In this way, each test line 202 fully covers the outer edge of the non-display area B of the flexible display screen, so that the breakage of the outer edge of the non-display area B of the flexible display screen can be comprehensively detected, and the accuracy of the breakage detection is improved.
