Fig. 3 to 5 illustrate schematic views of the lamp panel structure 10, and fig. 1 and 2 illustrate schematic views of a display device.

As shown in fig. 1 to 5, in an embodiment of the display device of the present utility model, the display device includes a display panel 20 and a backlight module. The display panel 20 is a liquid crystal display panel 20. The backlight module is a direct-in type backlight module, and the backlight module comprises a lamp panel structure 10.

With continued reference to fig. 3, the lamp panel structure 10 includes a substrate 11, a touch sensing assembly, and a plurality of first light emitting elements 12. The substrate 11 includes a circuit structure. The touch sensing assembly includes a plurality of emitters 13 and a plurality of receivers 14, the first light emitting element 12, the emitters 13 and the receivers 14 are respectively mounted on the same side of the substrate 11, and the first light emitting element 12, the emitters 13 and the receivers 14 are respectively electrically connected with the circuit structure.

The first light emitting element 12 is a backlight light source, which may also be referred to as an illumination light source, and illuminates the liquid crystal display panel 20 through the first light emitting element 12 to achieve a display effect of the display device. The first light emitting element 12 may be, but is not limited to, a cold cathode fluorescent lamp (ColdCathodeFluorescentLamp, CCFL), a Light Emitting Diode (LED). The first light emitting element 12 in this embodiment can emit at least white light.

The transmitter 13 is used for transmitting the sensing light 93, and the receiver 14 is used for receiving the sensing light 93. The transmitter 13 emits the sensing light 93 toward the display panel 20, and when the user does not touch the screen or touches the screen, the intensity of the sensing light 93 received by the at least one receiver 14 changes, and the processor in the display device determines the touch position according to the change of the signal received by the touch sensing component, so as to perform touch response.

In this embodiment, the transmitter 13 is an infrared transmitter 13, and the receiver 14 is an infrared receiver 14. The sensing light 93 is infrared, in other words, the emitter 13 is used for emitting infrared, the receiver 14 is used for receiving infrared, and the sensing light 93 is invisible to the naked human eye.

In other embodiments, the emitter 13 may also be used to emit other invisible light.

In one embodiment, the first light emitting element 12 is a white LED and the emitter 13 is an infrared LED.

In this embodiment, the backlight module includes a diffusion plate 30, the diffusion plate 30 is disposed between the display panel 20 and the lamp panel structure 10, and the first light emitting element 12, the emitter 13, and the receiver 14 are disposed on one side of the substrate 11 close to the diffusion plate 30 and close to the display panel 20. A certain distance is reserved between the diffusion plate 30 and the lamp panel structure 10. The illumination light 92 emitted by the first light emitting element 12 is refracted and diffusely scattered by the diffusion plate 30 to form a uniform area light source, and provides a sufficient light source for the display panel 20. In other words, the diffusion plate 30 is used to modify the point light sources of the plurality of first light emitting elements 12 into surface light sources.

The principle of the display device of the present embodiment for implementing touch control is:

when the finger, stylus or other touch object 91 does not contact the screen, the emitter 13 emits the sensing light 93 toward the diffusion plate 30, a part of the sensing light 93 passes through the diffusion plate 30 and is emitted to the display panel 20, another part of the sensing light 93 is reflected by the diffusion plate 30 and is reflected toward the substrate 11, the receiver 14 receives the sensing light 93, and after the reflected sensing light 93 is received and read, the optical signal is converted into an electrical signal, and the electrical signal is stable under the condition that the touch object 91 is not subjected to external force. As shown in fig. 1, when the touch object 91 contacts the screen, since the touch object 91 is blocked at the front side of the display panel 20, the sensing light 93 striking the touch object 91 through the display panel 20 is reflected back by the touch object 91, at this time, the light quantity of the sensing light 93 received by at least some of the receivers 14 is increased, the reflected sensing light 93 is received and read to form a strong electric signal, and finally, the specific touch coordinates are formed through calculation of the processor in the display device, and the corresponding screen action is formed through feedback, so as to realize the touch response.

Of course, in other embodiments, when the finger, stylus or other touch object 91 is not in contact with the screen, all the sensing light 93 can be transmitted through the diffusion plate 30 to the display panel 20.

In this embodiment, the substrate 11 is a circuit board, which may be, but is not limited to, a PCB board or a flexible circuit board. The first light-emitting element 12, the emitter 13 and the receiver 14 are directly integrated on the same circuit board, and when the first light-emitting element 12, the emitter 13 and the receiver 14 are installed, the elements are electrically connected with a circuit and fixed, so that the whole structure of the backlight module can be simplified, and the assembly, the disassembly and the maintenance are convenient.

In other embodiments, the substrate 11 may also include a main board body and a circuit board, and the first light emitting element 12, the emitter 13, the receiver 14 and the circuit board are electrically connected to each other, and then the elements are fixed on the main board body.

The first light emitting element 12, the transmitter 13, the receiver 14 may be electrically connected to the circuit board by, but not limited to, a patch, a wire connection, or the like.

In this embodiment, the touch sensing component set in the frame 60 is canceled, and the touch sensing component is set in the backlight module, so that the thickness and width of the frame 60 are reduced while the touch sensing function is provided, thereby reducing the volume and weight of the frame 60, further reducing the volume and weight of the whole display device, and being beneficial to the light and thin design of the display device. And, the reduction of the width of the frame 60 is beneficial to improving the area occupation ratio of the screen on the whole display equipment, and improving the watching and using experience of users.

Referring to fig. 3 to 5, in order to ensure that the first light emitting element 12 uniformly illuminates the display panel 20, and ensure the display effect of the display panel 20, and simultaneously in order to provide a more accurate touch sensing effect under the condition that the number of the emitters 13 is limited, the first light emitting element 12 and the emitters 13 in the embodiment are arranged in the following manner:

the first light emitting elements 12 are disposed on the substrate 11 in a dispersed manner, and the emitters 13 are disposed on the substrate 11 in a dispersed manner to provide more uniform illumination light 92 and sensing light 93 to the display panel 20, respectively.

The first light emitting elements 12 are arranged to be staggered with the emitters 13 along a first direction of the substrate 11, and the first light emitting elements 12 are arranged to be staggered with the emitters 13 along a second direction of the substrate 11. The first direction and the second direction are perpendicular to each other. By arranging the two light emitting elements in at least two directions in a staggered manner, the two light emitting elements can be dispersed and uniformly arranged in the substrate 11 with a limited area at the same time, so as to provide good lighting effect and touch sensing effect.

In this embodiment, the first direction and the second direction are perpendicular to each other, the first direction is the x-axis direction, and the second direction is the y-axis direction. In this embodiment, the substrate 11 is a rectangular substrate 11, the first direction is the length direction of the substrate 11, and the second direction is the width direction of the substrate 11.

In other embodiments, the first direction may not be the x direction of the substrate 11, and the second direction may not be the y direction of the substrate 11. The first direction and the second direction may be diagonal directions of the substrate 11, or the like, and an angle between a ray extending in the first direction and a ray extending in the second direction may be an acute angle or an obtuse angle.

As shown in fig. 3, the meaning of "the first light emitting elements 12 are staggered with the emitters 13 along the first direction of the substrate 11" will be described in terms of the arrangement of the three first light emitting elements 12 and the three emitters 13 in the first horizontal row in the figure: the first light emitting element 12, the emitter 13, the first light emitting element 12, and the emitter 13 are sequentially arranged at intervals along the length direction of the substrate 11. Taking the first light emitting element 12 and the emitter 13 in the first vertical column as an example in the drawing, the meaning of "the first light emitting element 12 and the emitter 13 are staggered along the second direction of the substrate 11" is the same.

With continued reference to fig. 3 to 5, in order to improve the touch sensing accuracy under the condition that the number of transmitters 13 and receivers 14 is limited, the touch sensing elements are arranged as follows:

along a first direction of the substrate 11, the emitters 13 are staggered with the receivers 14. In this way, all or most of the receivers 14 are adjacent to at least two of the transmitters 13, so that the plurality of transmitters 13 and the plurality of receivers 14 can be distributed more uniformly, the number of the transmitters 13 near the periphery of the receivers 14 is increased, and further the touch accuracy is improved.

In this embodiment, the emitters 13 and the receivers 14 are also staggered along the second direction of the substrate 11.

With continued reference to fig. 3 to 5, in order to make the first light emitting element 12, the emitter 13 and the receiver 14 more reasonably distributed on the substrate 11, the display device has good display performance and touch sensing performance, three elements are arranged as follows:

the first light emitting elements 12, the emitters 13 and the receivers 14 on the substrate 11 are arranged to form element rows and element columns, the element rows are arranged along the y direction, and the element columns are arranged along the x direction and are perpendicular to the y direction.

The element rows include odd rows and even rows, and the element columns include odd columns and even columns. For ease of understanding, in fig. 4, the Pj region is an odd number row, the Po region is an even number row, and in fig. 5, the Lj region is an odd number column, and the Lo region is an even number column.

The odd rows comprise a plurality of first light-emitting elements 12 and a plurality of emitters 13, and the first light-emitting elements 12 and the emitters 13 are staggered; the odd columns comprise a plurality of first light-emitting elements 12 and a plurality of emitters 13, and the first light-emitting elements 12 and the emitters 13 are arranged in a staggered manner; the even rows include a number of receivers 14; the even columns include a number of receivers 14.

And, along the x-direction, the transmitters 13 are staggered with the receivers 14; in the y-direction, the transmitters 13 are staggered with respect to the receivers 14.

By this arrangement, not only the two light emitting elements (the first light emitting element 12 and the emitters 13) on the substrate 11 can be uniformly distributed, but also the receivers 14 can be prevented from being arranged at the edge, so that each receiver 14 can be adjacent to at least two emitters 13, and the touch sensing accuracy is improved.

With reference to fig. 1 and 3, in order to make the light emitted from the first light emitting element 12 and the emitter 13 strike the diffusion plate 30 more uniformly, and strike the display panel 20 more uniformly, so as to improve the display performance and touch accuracy of the display device, the lamp panel structure 10 further includes the first lens 15 and the second lens 16.

The first lens 15 is disposed on a side of the first light emitting element 12 away from the substrate 11, and the second lens 16 is disposed on a side of the emitter 13 away from the substrate 11, so that light emitted from the first light emitting element 12 and the emitter 13 is emitted to the diffusion plate 30 and the display panel 20 through the first lens 15.

The first lens 15 and the second lens 16 are used for optimizing light, and can increase the diffusion angle of the light, so that the illumination light 92 emitted by a single first light emitting element 12 and the sensing light 93 emitted by the emitter 13 can be irradiated in a larger range on the display panel 20 within a limited light path distance, the display effect is prevented from being influenced by the too concentrated light, the coverage area of the sensing light 93 can be enlarged under the condition that the number of the emitters 13 is limited, and even if the whole thickness of the display device is smaller, the good display effect and the good touch accuracy can be achieved.

The first lens 15 and the second lens 16 may have the structures shown in fig. 1 and 3, or may have structures other than those shown in the drawings. In the present embodiment, the first lens 15 is fixed to the substrate 11, and the second lens 16 is fixed to the substrate 11.

In this embodiment, the light diffusion particles are disposed on the diffusion plate 30, when the sensing light 93 hits the diffusion plate 30, a portion of the sensing light 93 will generate diffuse reflection, so that the sensing light 93 is reflected back to the lamp panel structure 10 more uniformly, so that when the finger does not touch the screen, the light signals of the sensing light 93 received by the plurality of receivers 14 are more uniform. In this way, the system may be configured to determine that the touch operation is generated when the change of the optical signal received by each receiver 14 is greater than the set value.

In this embodiment, the diffusion plate 30 includes a diffusion plate 30 body and a plurality of light diffusion particles; the light diffusion particles are disposed on the lower surface of the diffusion plate 30, i.e., the light diffusion particles are disposed on the side of the diffusion plate 30 body close to the lamp panel structure 10. The light diffusion particles may be provided on the surface of the diffusion plate 30 body by coating.

In other embodiments, the light diffusion particles may be disposed on a side of the diffusion plate 30 away from the lamp structure 10, or may be disposed inside the diffusion plate 30.

The light diffusion particles may be, but are not limited to, methyl methacrylate, styrene copolymer (MS), acryl (PMMA), polystyrene (PS), silvicon (Silicon), titanium dioxide (TiO 2), and Silicon dioxide (SiO 2).

With continued reference to fig. 1 and 2, in order to protect the display panel 20 from being scratched and damaged by the display panel 20, the display device further includes a protective layer 40, where the protective layer 40 is disposed on a side of the display panel 20 facing away from the diffusion plate 30. The protective layer 40 may be, but is not limited to, glass and a protective film.

The weight of the whole machine can be reduced by adopting thinned tempered glass or a tempered film with smaller thickness as the protective layer 40.

With reference to fig. 1 and 2, in order to enhance the display effect, the backlight module further includes an optical film 50, and a portion of the optical film 50 is disposed between the display panel 20 and the diffusion plate 30, and the optical film may be, but is not limited to, a brightness enhancement film, a diffusion film, and a reflection film.

The protective layer 40 is adhered to the display panel 20, the display panel 20 is adhered to the optical film 50, and the optical film 50 is adhered to the diffusion plate 30, in other words, the glass (or protective film), the display panel 20, the optical film 50 and the diffusion plate 30 are all adhered to form the display device, so that the thickness of the whole display device can be reduced, and a stable and flat plate body can be formed.

Therefore, on the basis of reducing the width and thickness of the frame 60, the flat plate body can be directly and integrally mounted to the frame 60, and the frame 60 does not need to be provided with a plurality of limiting structures for respectively limiting the glass, the display panel 20 and the diffusion plate 30. In other words, through the full-lamination arrangement of the glass (or the protective film), the display panel 20, the optical film 50 and the diffusion plate 30, the thickness of the frame 60 and the width occupied by the frame 60 on the front surface of the display device are reduced on the basis of ensuring the reliable installation of the glass (or the protective film), the display panel 20, the optical film 50 and the diffusion plate 30 by matching with the lamp panel structure 10 of the embodiment.

With continued reference to fig. 1 and 2, the display device includes a frame 60 and a back plate 70 connected to the frame 60, and an installation space is formed between the frame 60 and the back plate 70; the display panel 20 and the backlight module are arranged in the installation space; the display panel 20 is disposed on a side of the backlight module facing away from the back plate 70.

In this embodiment, the display device further includes a reflective plate 80 disposed in the installation space and disposed on a side of the diffusion plate 30 away from the display panel 20, wherein the reflective plate 80 is used for completely transmitting the light emitted by the light source to the diffusion plate 30, so as to reduce the useless loss as much as possible.
