The circuit board 120 is installed on the frame 110, the lamp beads 130 are fixed on the circuit board 120, the lamp beads 130 can adopt LED (Light Emitting Diode) lamp beads 130, most of electric energy consumed by the LED lamp beads 130 is used for Emitting Light, only a small part of electric energy is used for generating heat, and therefore the LED lamp beads 130 have the advantage of high energy utilization rate and meet the design requirements of low carbon and environmental protection. The whole hand-held screen 10 generates less heat, and the hand-held screen 10 cannot be damaged due to excessive local accumulated heat.
In some embodiments, the circuit board 120 is provided with a plurality of through holes 121, the through holes 121 are in a long shape, the plurality of through holes 121 in the long shape are uniformly arranged at intervals along the length direction of the circuit board 120, when the circuit board 120 is mounted on the frame 110, the grid holes 113 on the frame 110 and the through holes 121 on the circuit board 120 jointly form the hollow-out grooves 103 of the display module 100, the hollow-out grooves 103 penetrate through the display surface 101 and the back surface 102 of the display module 100, and the through-out grooves formed on the display module 100 have the following three advantages:
first, can increase the heat radiating area of display module assembly 100, the heat that display module assembly 100 produced can be followed and is discharged outside fast in this fretwork groove 103, improves the heat dispersion that the screen 10 was lifted to the hand, simultaneously, when operating personnel swung the hand and lifts the screen 10, produces the air current in the fretwork groove 103, under the effect of this air current, the heat that the screen 10 produced was lifted to the hand more accelerated the fashion and discharges to the external world, further improves the radiating effect that the screen 10 was lifted to the hand. Secondly, in the process that the operator swings the hand-lift screen 10, the air flow can enter the side where the back 102 of the display module 100 is located from the side where the display surface 101 of the display module 100 is located through the hollow groove 103, so that the air flow is effectively prevented from directly acting on the display surface 101 or the back 102 of the display module 100, the air resistance in the swing process of the hand-lift screen 10 is reduced, the labor intensity of the operator is relieved, and the damage to the hand-lift screen 10 under the condition of overlarge air resistance is also prevented. Thirdly, the weight of the display module 100 and the whole hand-lifting screen 10 can be reduced, the workload caused by the weight of the hand-lifting screen 10 is reduced, the labor intensity of operators is further reduced, and the convenience in operation of the hand-lifting screen 10 is improved.
Referring to fig. 1 to 5, the power supply 200 is mounted on the back surface 102 of the display module 100, i.e., on the frame 110 of the display module 100, the power supply 200 may be a lithium battery, etc., and the power supply 200 may directly supply power to the display module 100. Thereby need not to connect external power supply unit and lift the hand screen through the power cord, when operating personnel swung the hand and lifted screen 10, can break away from power cord to operating personnel's interference and constraint, operating personnel can lift screen 10 with the hand and carry out the free operation in any occasion, reduces operating personnel's working strength, improves operating personnel's convenience. Similarly, the power source 200 is mounted on the back surface 102 of the display module 100, i.e. on the frame 110 of the display module 100, and the signal transmitter 300 is used for signal transmission between the display module 100 and the outside and between the display modules 100. Signal transmitter 300 can adopt the wiFi signal seat, can realize the wireless transmission of display module assembly 100 to the signal through the wiFi signal seat to omit the signal line with display module assembly 100 lug connection, thereby break away from power cord to operating personnel's interference, operating personnel can carry out the free operation with hand-lifting screen 10 in any occasion, reduces operating personnel's working strength, improves operating personnel's convenience.
Particularly, for the conventional hand-held screen, in the use process of the hand-held screen, the power line is used for connecting the display module 100 with the external charging device, and the signal line is used for connecting the display module 100 with the external signal transmission device. Under the restriction of both lengths of power cord and signal line, operating personnel can only lift the screen with the hand and operate at the within range that power cord and signal line length allowed, and power cord and signal line both's weight can increase operating personnel's working strength simultaneously, and power cord and signal line produce the drag resistance to the operation that the screen 10 was lifted to the hand, also can improve operating personnel's working strength, make power cord and signal line break away from the hand even and lift screen 10, lead to the hand to lift the unable normal work of screen 10. Furthermore, in the situation where external charging equipment and signal transmission equipment cannot be provided, the hand-held screen 10 cannot be used at all, which limits the applicability of the conventional hand-held screen 10 to various application scenarios.
For the hand-held screen 10 in the above embodiment, various interferences of the power line and the signal line to the mobile phone screen are eliminated, the working strength of the operator is reduced, and the hand-held screen 10 can be freely operated without the limitation of the power line and the signal line. Meanwhile, the restriction of external charging equipment and signal transmission equipment on the mobile phone screen is eliminated, and the applicability of the handheld screen 10 to various application scenes is improved.
Certainly, when the power supply 200 and the signal transmitter 300 are in a fault or allowed by other conditions, the power supply 200 and the signal transmitter 300 can be unloaded and are directly connected with the charging device and the signal transmission device through power lines and signal lines respectively, so that the free switching of the hand-held screen 10 between the wireless state and the wired state is realized, and the applicability of the hand-held screen 10 to various application scenes is further improved.
In some embodiments, to further improve the convenience of the operation of the hand-held screen 10, the hand-held screen 10 may further include a handle 500, and the handle 500 is mounted on the back surface 102 of the display module 100, i.e., on the frame 110 of the display module 100. The operator directly holds the handle 500 to operate the entire hand-held screen 10, so as to swing the hand-held screen 10 in various postures. The handle 500 may be made of a metal material, and in other embodiments, the handle 500 may be made of a plastic material or a wood material.
Referring to fig. 1 to 5, in some embodiments, the number of the display modules 100 is two, and the two display modules 100 are rotatably connected (the direction indicated by the dotted arrow in fig. 1 is the rotation direction of the display module 100), for example, the two display modules 100 are rotatably connected by a rotating mechanism such as a hinge. Through rotating two display module assembly 100, can realize the various show gestures of hand-lift screen 10, further improve the expressive force of hand-lift screen 10. The hand-held screen 10 may further include a limiting member 400, and the limiting member 400 is also mounted on the frame 110 and located on the back surface 102 of the whole display module 100. When two display module assemblies 100 rotate to extreme position, the locating part 400 on two display module assemblies 100 forms the effect of mutual support and pressure to further rotate constitution to display module assembly 100 and interfere, make two display module assemblies 100 can only rotate at reasonable angular range, avoid two display module assembly 100 direct impact and produce the damage. The position-limiting member 400 can be made of a metal material, and in other embodiments, the position-limiting member 400 can also be made of a plastic material or a wood material.
The two curved surfaces 410 may be further disposed on the limiting members 400, and under the condition that the two limiting members 400 directly abut against each other, the two curved surfaces 410 enclose a gap, and at the position of the gap, the two limiting members 400 do not directly contact each other, in other words, the two limiting members 400 directly contact each other at other positions outside the curved surfaces 410, so that the direct contact area of the two limiting members 400 is reduced, the friction force between the two limiting members 400 is reduced, thereby reducing the rotation resistance of the display module 100, facilitating the two display modules 100 to smoothly rotate from the limiting positions to other positions, and reducing the working strength of an operator. Meanwhile, the through hole 430 may be formed in the middle of the limiting member 400, and the through hole 430 effectively reduces the weight of the limiting member 400, thereby facilitating the operation of lifting the screen 10 by hand.
In some embodiments, the limiting member 400 is provided with an anti-collision sheet 420, the anti-collision sheet 420 can be covered on the limiting member 400, the anti-collision sheet 420 has certain elasticity, for example, the anti-collision sheet 420 can be made of sponge or elastic silica gel. When the two display modules 100 rotate to the extreme positions, the two anti-collision sheets 420 are directly contacted by the limiting members 400, so that the two limiting members 400 are prevented from being in hard collision due to direct contact. Because the anti-collision sheet 420 has certain elasticity, the collision energy between the limiting members 400 can be effectively absorbed, and the display module 100 is prevented from being damaged by the collision impact force generated by the limiting members 400.
In some embodiments, the frame 110 of the display module 100 may further include an inclined surface 114, and the inclined surface 114 may form an angle with the display surface 101 and the back surface 102 of the display module 100. Through setting up inclined plane 114, can make two display module assembly 100 eliminate interference and rotate smoothly in the within range that the extreme position was injectd, of course, when two display module assembly 100 rotated to the extreme position, inclined plane 114 on two display module assembly 100 can laminate each other or keep setting for the interval. In other embodiments, the hand-held screen 10 may further include three or more than three display modules 100 rotatably connected to each other.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
