Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic devices, in particular to a segment display screen and a fuel dispenser intelligent control integrated machine. Background Art
[0002] The segment display screen in the prior art generally includes a front substrate, a rear substrate disposed opposite to the front substrate, a common electrode disposed on the rear surface of the front substrate, a driving display electrode module disposed on the front surface of the rear substrate, and a display medium layer disposed between the common electrode and the driving display electrode module; the driving display electrode module includes a driving electrode and a display electrode (or segment electrode), the driving electrode is connected to the display electrode for supplying power to the display electrode, and after the display electrode is powered on, an induction electric field is formed with the common electrode, and the induction electric field causes the area of the display medium layer corresponding to the display electrode to emit light, so as to present the characters and graphics enclosed by the display electrode.
[0003] What is not desired and is likely to occur is that an induction electric field is also formed between the driving electrode and the common electrode, resulting in the display of the driving electrode on the display screen.
[0004] To prevent the display of the driving electrode on the display screen, an insulating layer is disposed on the front surface of the driving electrode to prevent the formation of an induction electric field between the driving electrode and the common electrode. However, this method is difficult to completely prevent the formation of an electric field between the driving electrode and the common electrode. The reason is that in order to minimize the projected area of the driving electrode and minimize the resistance of the driving electrode, the aspect ratio of the driving electrode is usually set to be small. Therefore, an induction electric field that cannot be ignored is also formed between the side wall in the width direction of the driving electrode and the common electrode, and this induction electric field can still cause the driving electrode to be displayed. Summary of the Utility Model
[0005] In view of the above technical problems existing in the prior art, the utility model provides a segment display screen and a fuel dispenser intelligent control integrated machine.

[0033] To keep the following description of the embodiments of the present utility model clear and concise, the detailed descriptions of known functions and known components are omitted in the present utility model.
[0034] As Figures 1 to 4 shown, an embodiment of the present utility model discloses a segment code display screen, which can be applied to an integrated machine of a fuel dispenser. The segment code display screen includes: a front substrate 11, a rear substrate 12, a common electrode 21, and a driving display electrode 22 module.
[0035] The rear substrate 12 is opposite to the front substrate 11 and is located at the rear side of the front substrate 11; the front substrate 11 is made of a transparent material, so that the graphics and texts can be displayed through the front substrate 11. The common electrode 21 is located on the rear surface of the front substrate 11 and is opposite to and attached to the rear plate surface of the front substrate 11 as a whole. The common electrode 21 is made of a transparent material, so that the common electrode 21 does not affect the display of graphics and texts.
[0036] The driving display electrode 22 module is arranged on the front surface of the rear substrate 12, and a display medium 30 is filled between the common electrode 21 and the driving display electrode 22 module.
[0037] The driving display electrode 22 module includes a driving electrode 23 and a display electrode 22. The display electrode 22 can also be called a segment code electrode. The end of the driving electrode 23 is electrically connected to the display electrode 22 to supply power to the display electrode 22. After the display electrode 22 is powered on, an induced electric field is formed between the display electrode 22 and the common electrode 21. The induced electric field makes the area of the display medium 30 corresponding to the display electrode 22 emit light, so as to present graphics and texts.
[0038] All the driving electrodes 23 have a main body section 231, and the aspect ratio of the main body section 231 is small. As Figure 3 and Figure 4 shown, some of the driving electrodes 23 need to be electrically connected to the distal display electrode 22 through the proximal display electrode 22. Therefore, the present utility model also configures an overlapping section 232 on these driving electrodes 23. The overlapping section 232 is located at the position where it intersects with the display electrode 22. And a sinking groove 221 is correspondingly formed on the rear surface of the display electrode 22. The overlapping section 232 is embedded in the sinking groove 221. The thickness of the overlapping section 232 is smaller than the thickness of the main body section 231, while the width of the overlapping section 232 is much larger than the width of the main body section 231. In this way, the rear plate surface of the display electrode 22 and the rear plate surface of the driving electrode 23 are located on the same plane. Thus, the display electrode 22 and the driving electrode 23 are basically located on the same plane, which is beneficial to the flat attachment of the two electrodes to the rear substrate 12. In addition, since the width of the overlapping section 232 increases, the resistance will not increase.
[0039] In the present utility model:
[0040] A first insulating layer 61 is disposed on the main body section 231 of the driving electrode 23. The first insulating layer 61 covers both the front surface and the two side walls of the main body section 231. In this way, the front surface and the two side walls of the main body section 231 will not form an induced electric field with the common electrode 21, thereby preventing the main body section 231 of the driving electrode 23 from being displayed.
[0041] A second insulating layer 62 is disposed on the overlapping section 232 of the driving electrode 23. The second insulating layer 62 covers the front surface of the overlapping section 232. Since the overlapping section 232 is shielded by the display electrode 22, the second insulating layer 62 is not used to prevent the formation of an induced electric field with the common electrode 21. The function of the second insulating layer 62 is to prevent the driving electrode 23 from being short-circuited with the passing display electrode 22.
[0042] In some preferred embodiments, a colloid is coated on the rear substrate 12. The thickness of the colloid is greater than the thickness of the driving display electrode 22 module. After the colloid is formed, a balancing layer 40 is formed. The front surface of the balancing layer 40 is higher than the front surfaces of the driving electrode 23 and the display electrode 22, so that the driving electrode 23 and the display electrode 22 are both immersed in the balancing layer 40.
[0043] In some preferred embodiments, a partition dam 50 is provided between the balancing layer 40 and the common electrode 21. The partition dam 50 encloses accommodation cavities arranged in a matrix. The display medium 30 is electronic ink, and the electronic ink is filled in the accommodation cavities. The advantage of providing the partition dam 50 is that the partition dam 50 divides the display medium 30 into grids arranged in a matrix, thereby restricting the flow of fluid media such as electronic ink, so that the display of each area of the graphic and text is uniform.
[0044] The present utility model also discloses a fuel dispenser intelligent control integrated machine, which includes the above-mentioned segment code display screen.
