[0031] The following examples are described with reference to Figures 1 to 6 .

[0032] The display device provided by the embodiment of the application is used for temporary traffic information display, and comprises:

[0033] A protective shell 1 is provided with a display panel 11, the front end surface of the display panel 11 is provided with a plurality of lamp beads, the plurality of lamp beads are arranged into different preset characters 12, the rear end surface of the display panel 11 is provided with a power supply, and the power supply is connected with the lamp beads.

[0034] A protective cover 2 is sealingly connected with one end surface of the protective shell 1, and the protective cover 2 is made of transparent material.

[0035] The display device of the utility model has the plurality of lamp beads arranged on the front end surface of the display panel 11 of the protective shell 1, and the plurality of lamp beads are arranged into different preset characters 12. The preset characters 12 are arranged by the lamp beads, and the characters are overlapped together. When the characters need to be displayed, the lamp beads of the characters are lightened, the number of the lamp beads is reduced, the controller module is saved, and the cost of the variable information board is reduced.

[0036] Meanwhile, the protective cover 2 is sealingly connected with one end surface of the protective shell 1, can effectively prevent the dust, water vapor and other external impurities from entering the inside of the equipment, and has a good protection effect on the display panel 11, the lamp beads and the power supply and other components. The protective cover 2 is made of transparent material, does not affect the normal display of the characters displayed by the lamp beads, and ensures the clear visibility of the display effect.

[0037] Specifically, the plurality of lamp beads comprise a special lamp bead group part corresponding to different characters and a shared lamp bead group part, the lamp beads of the special lamp bead group part are connected in parallel, and the shared lamp bead group part is connected in parallel.

[0038] The lamp beads of the special lamp bead group part corresponding to different characters are connected in parallel and connected with the power supply through a special switch; and the shared lamp bead group part is connected in parallel and connected with the power supply through a shared switch.

[0039] When the preset characters 12 comprise a first character and a second character, the first character comprises a first lamp bead group part and a shared lamp bead group part, and the second character comprises a second lamp bead group part and a shared lamp bead group part.

[0040] In the embodiment, it is assumed that the first character and the second character are "slow" and "stop" respectively, and the display principle of the specific characters is as shown in the circuit control Figures 4-6 .

[0041] The lamp beads LED_SLOW1-117 and LED_COMM1-91 jointly form the "slow" character.

[0042] The lamp beads LED_STOP1-72 and LED_COMM1-91 jointly form a "stop" character;

[0043] The lamp beads LED_SLOW1-117 are a part of the exclusive lamp bead group of the "slow" character; the lamp beads LED_STOP1-72 are a part of the exclusive lamp bead group of the "stop" character; and the lamp beads LED_COMM1-91 are a part of the common lamp bead group of the "slow" character and the "stop" character.

[0044] In the embodiment, when the display device is used, the "slow" character and the "stop" character can be displayed by light emission, and the information board and the control card with high cost are not needed. When all the lamp beads of the display device are off, only the "slow" and "stop" overlapping characters can be vaguely seen, and the "slow" character or the "stop" character can be clearly seen only when the corresponding lamp beads are on, so that the false prompt is avoided.

[0045] In the embodiment, the lamp beads are divided into the exclusive lamp bead group part corresponding to different characters and the common lamp bead group part, and are connected in parallel. The parallel circuit has the characteristic that the voltages of the branches are equal, so that each lamp bead can work at the rated voltage and thus normally emit light. Meanwhile, the parallel connection also makes that when a lamp bead fails, the normal work of other lamp beads is not affected, and the information of the characters can still be displayed in integrity through the remaining normal lamp beads. The lamp beads of the exclusive lamp bead group part corresponding to different characters are connected in parallel through the exclusive switches and the power supply, and the lamp beads of the common lamp bead group part are connected in parallel through the common switch and the power supply. By controlling the on-off of the exclusive switches and the common switch, the display of different characters can be flexibly controlled. When a specific character needs to be displayed, the corresponding exclusive switch and common switch are opened, so that the corresponding exclusive lamp bead group and common lamp bead group are powered on to emit light, thereby forming the required character; and the switches corresponding to the characters that do not need to be displayed are closed, so that the switching display of the characters is realized.

[0046] The different lamp bead groups are respectively controlled through the exclusive switches and the common switch, so that the flexible combination display of multiple characters can be realized. According to the actual needs, different character contents can be quickly and conveniently switched to display, so that the information display needs in different scenes are met, and the flexibility and practicality of the display device are improved.

[0047] Meanwhile, when only part of the characters need to be displayed, the switches corresponding to the lamp bead groups of irrelevant characters can be closed, and only the lamp bead groups that need to be displayed are powered on to emit light, so that the unnecessary light emission of the lamp beads to consume electric energy is avoided, thereby achieving the energy-saving effect. The design of the common lamp bead group part can reduce the number of lamp beads, so that the hardware cost is reduced while the display needs of multiple characters are met. Meanwhile, due to the reduction of the number of lamp beads, the corresponding power supply power and other requirements can also be appropriately reduced, so that the overall cost of the device is further reduced.

[0048] In the present embodiment, the lamp bead uses a light emitting diode as a light source. In other embodiments, the lamp bead can also use a cold cathode fluorescent lamp, a hot cathode fluorescent lamp or an electroluminescent device as a light source.

[0049] Specifically, the preset character 12 is arranged at the middle position of the display panel 11.

[0050] Arranging the preset character 12 at the middle position of the display panel 11 can make it a visual focus, so that people can more easily pay attention to the displayed content and improve the efficiency of information transmission.

[0051] Specifically, the display device further comprises a sealing strip 3; the opening end of the protective shell 1 is provided with a connecting ring 13, the connecting ring 13 is provided with a first annular groove 14, the protective cover 2 is provided with a mounting ring 21 matched with the connecting ring 13, the mounting ring 21 is provided with a second annular groove 22 matched with the first annular groove 14, and the sealing strip 3 is embedded in the first annular groove 14 and the second annular groove 22.

[0052] By embedding the sealing strip 3 in the first annular groove 14 of the connecting ring 13 of the protective shell 1 and the second annular groove 22 of the mounting ring 21 of the protective cover 2, a tight sealing structure can be formed between the protective shell 1 and the protective cover 2. Dust, water vapor, foreign matter and the like can be effectively prevented from entering the inside of the display device, so as to avoid damage to the display panel 11, the lamp bead, the power supply and the like caused by these impurities, thereby prolonging the service life of the device and ensuring stable operation of the device in various harsh environments.

[0053] In addition, the connecting ring 13 and the mounting ring 21 are matched, and the gap between them is filled by the sealing strip 3, so that the connection between the protective shell 1 and the protective cover 2 is more tight and stable. The elastic effect of the sealing strip 3 can compensate for the possible size error or slight deformation between the connecting ring 13 and the mounting ring 21, reduce the possibility of separation of the protective cover 2 from the protective shell 1 caused by external forces such as vibration and impact, reduce the direct impact on the protective shell 1 and the protective cover 2, reduce the risk of loosening or damage of internal components caused by vibration, and improve the stability of the device.

[0054] In addition, the display device in the above embodiment further comprises a switch button 4. By arranging the switch buttons 4 of different lamp bead parts on the side end of the display device, the lighting and turning off of different lamp bead parts can be controlled by controlling different switch buttons 4.

[0055] In summary, the foregoing description of the specific exemplary embodiments of the present application is for the purpose of illustrating and explaining, and these descriptions are not intended to limit the present application to the precise forms disclosed, and it is obvious that many changes and variations can be made according to the above teachings, although embodiments of the present application have been shown and described, the specific embodiments are merely an explanation of the present application, and are not a limitation of the present application, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner, the exemplary embodiments are selected and described for the purpose of explaining the specific principles of the present application and its practical application, so that those skilled in the art can make modifications, replacements, variations and various different selections and changes to the embodiments according to needs after reading the specification without departing from the principles and spirits of the present application, but as long as within the scope of the claims of the present application, all are protected by the patent law.
