Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0039] A first aspect of an embodiment of the present invention provides an optoelectronic package.

[0040] like Figure 1 As shown, Figure 1 This is a schematic diagram of a first structural embodiment of an optoelectronic package provided by an embodiment of the present invention. In this embodiment, the optoelectronic package is used to electrically connect to a previous optoelectronic package or controller 100 and to a subsequent optoelectronic package. The optoelectronic package includes an integrated light source module, a sensing module, and a driving module.

[0041] The driving module is electrically connected to the light source module and the sensing module respectively. The sensing module is used to sense touch and is electrically connected to the controller 100 through a signal bus. The driving module is also used to electrically connect to the driving module or controller 100 of the previous level optoelectronic package and to the driving module of the next level optoelectronic package.

[0042] Driver module for:

[0043] Output control signal to the sensing module;

[0044] Receive the light source driving signal output by the controller 100, and drive the electrically connected light source module to light up according to the light source driving signal;

[0045] Sensing modules for:

[0046] When a touch is sensed, a trigger signal is output to the controller 100, so that the controller 100 determines the physical address of the optoelectronic package including the sensing module and performs corresponding operations according to the trigger signal and the transmission time of the trigger signal, and outputs a light source driving signal to the driver module of the set optoelectronic package according to the trigger signal.

[0047] In this embodiment, when the optoelectronic package is installed in the keyboard for use, it is serially connected to the controller 100 in sequence to realize step-by-step signal transmission. For example, the first optoelectronic package 200 is respectively connected to the controller 100 and the second optoelectronic package 300, and the second optoelectronic package 300 is also connected to the third optoelectronic package, and so on. The light source driving signal emitted by the controller 100 is sequentially transmitted to at least one designated optoelectronic package through the optoelectronic package. A driving module, a sensing module and a light source module are integrated inside each optoelectronic package. The driving module is connected to the sensing module and the light source module of this stage. At the same time, it is also used to connect to the controller 100 or the driving module of the previous stage and the driving module of the next stage. For example, the first driving module 210 in the first optoelectronic package 200 is respectively connected to the first light source module 220 and the first sensing module 230, and the second driving module 310 in the second optoelectronic package 300 is respectively connected to the second light source module 320 and the second sensing module 330. The first driving module 210 is respectively connected to the controller 100 of the previous stage 00 and the subsequent second driver module 310, each driver module provides a control signal to the sensing module 230 connected to it, so that the corresponding sensing module is powered on and started. Taking the first optoelectronic package 200 as an example, the first driver module 210 provides a control signal to the first sensing module 230. When the first sensing module 230 is powered on and touched, it outputs a trigger signal to the controller 100. The controller 100 determines the physical address of the touched optoelectronic package by detecting the trigger signal and combining the transmission time between devices. The controller 100 performs corresponding operations based on the physical address of the first sensing module 230, such as outputting corresponding read and write instructions, return instructions, and delete instructions. In addition, because different sensing modules have different trigger signals and transmission times, the transmission time and received trigger signal can be used to determine which optoelectronic package is touched, preventing erroneous judgment when multiple sensing modules are touched at the same time, achieving anti-ghost key function, and eliminating the need to set additional high-impedance circuits or series resistors, thereby simplifying the circuit structure of the keyboard.

[0048] At the same time, the controller 100 that receives the trigger signal also outputs a light source driving signal to the set optoelectronic package. The set optoelectronic package can be any one or more of the first optoelectronic package 200, the second optoelectronic package 300, etc., and is specifically set according to the lighting requirements and rules. The driving module of at least one optoelectronic package that receives the light source driving signal outputs a dimming signal of corresponding size to the connected light source module according to the light source driving signal, thereby controlling the light source module to display light of corresponding color, thereby achieving a colorful effect at the corresponding position of the keyboard. The other driving modules, light source modules and sensing modules have the same working principle and will not be described in detail here. The driving module is connected to drive the light source module and the sensing module at the same time and is integrated. There is no need to set up driving modules separately to drive the light source module and the sensing module separately, which simplifies the circuit structure of the keyboard and reduces the design cost of the keyboard.

[0049] The drive module can be powered by an external power module.

[0050] The sensing module may be a light sensing module, such as an infrared light sensing module, and the structure of the sensing module may be configured accordingly as required.

[0051] The light source module may include a red LED chip, a green LED chip, and a blue LED chip, and the specific structure is selected according to the color display requirements of the keyboard.

[0052] The driving module can be a driving chip, and the specific structure is not limited.

[0053] By using a light source module, a sensing module and a driving module to form an optoelectronic package, the sensing module outputs a trigger signal to the controller 100 based on touch control. The controller 100 determines the physical address of the optoelectronic package containing the sensing module based on the trigger signal and performs corresponding operations. At the same time, it outputs a light source driving signal to the set driving module of the optoelectronic package, thereby driving the corresponding light source module to light up. The optoelectronic package realizes synchronous driving of the light source and the button, without the need to set up a separate driving circuit, which simplifies the circuit structure and reduces the design cost.

[0054] like Figure 2 As shown, in one embodiment, the first clock signal terminal of the driving module is used to be electrically connected to the second clock signal terminal of the driving module of the previous-stage optoelectronic package or the clock signal terminal of the controller 100, the second clock signal terminal of the driving module is used to be electrically connected to the first clock signal terminal of the driving module of the next-stage optoelectronic package, the first data signal terminal of the driving module is used to be electrically connected to the second data signal terminal of the driving module of the previous-stage optoelectronic package or the data signal terminal of the controller 100, and the second data signal terminal of the driving module is used to be electrically connected to the first data signal terminal of the driving module of the next-stage optoelectronic package.

[0055] In this embodiment, the driving modules of the optoelectronic packages sequentially transmit data signals and clock signals through a cascaded two-wire transmission mode, which simplifies electrical connection and reduces circuit layout space.

[0056] like Figure 3 As shown, in one embodiment, the power terminal of the optoelectronic package is used to input power supply through a power bus, and the ground terminal of the optoelectronic package is used to electrically connect to a common ground through the ground bus.

[0057] In this embodiment, each optoelectronic package obtains a corresponding working power supply by connecting to the power bus, and is connected to the common ground by connecting to the ground bus, thereby ensuring reliable operation.

[0058] Please continue reading Figure 3In one embodiment, the light source module includes at least one light emitting unit; the anode terminal of the light emitting unit is electrically connected to the power terminal of the optoelectronic package, and the cathode terminal of the light emitting unit is electrically connected to the signal terminal of the driving module.

[0059] In this embodiment, the light-emitting unit is connected to the driving module and the power supply end of the optoelectronic package. The light-emitting unit displays light of corresponding color according to the dimming signal output by the driving module. In one embodiment, the light-emitting unit includes R / G / B LED chips, and the R / G / B LED chips perform color mixing and display according to the received dimming signal, thereby realizing the function of colorful key buttons.

[0060] Please continue reading Figure 3 In one embodiment, the feedback signal terminal C of the optoelectronic package is used to be electrically connected to the controller 100 via a signal bus, and the sensing module includes a light emitting unit and a light receiving unit;

[0061] The anode terminal of the light emitting unit is electrically connected to the power supply terminal VDD of the optoelectronic package, the cathode terminal of the light emitting unit is electrically connected to the signal terminal of the driving module, and the light receiving unit is electrically connected to the feedback signal terminal C, the power supply terminal VDD and the ground terminal GND of the optoelectronic package respectively;

[0062] The light emitting unit is used to emit light according to the control signal output by the driving module;

[0063] The light receiving unit is used to receive the reflected light emitted by the light emitting unit when the optoelectronic package is touched, and send a trigger signal to the controller 100 .

[0064] In this embodiment, the feedback signal terminal C of the optoelectronic package is electrically connected to the signal bus and the signal output terminal of the sensing module, that is, electrically connected to the light receiving unit, and feeds back the trigger signal output by the light receiving unit to the controller 100 through the signal bus. Taking the first sensing module 230 of the first optoelectronic package 200 as an example, the first sensing module 230 includes a first light emitting unit 231 and a first light receiving unit 232. One end of the first light emitting unit 231 is connected to the power end, and the other end of the first light emitting unit 231 is connected to the first driving module 210. The first driving module 210 outputs a control signal to the first light emitting unit 231 to control the first light emitting unit 231 to light up and emit light. The first light receiving unit 232 is respectively connected to the power end VDD, the ground end GND and the feedback signal terminal C. Figure 5As shown, when the first sensing module 230 is touched, the light emitted by the first light emitting unit 231 is reflected by the keycap 233 or other mechanical structures to the first light receiving unit 232, prompting the first light receiving unit 232 to send a trigger signal to the controller 100. The controller 100 determines the physical address of the first optoelectronic package 200 that sends the trigger signal based on the trigger signal and the transmission time, and outputs a light source driving signal to the driving module of the set optoelectronic package, thereby driving the corresponding light-emitting unit to emit light of the corresponding color.

[0065] In summary, the optoelectronic package is provided with a clock signal terminal CLOCK, a data signal terminal DATA, a feedback signal terminal C, a power supply terminal VDD and a ground terminal GND. The clock signal terminal CLOCK and the data signal terminal DATA of the optoelectronic package are respectively connected to the clock signal terminal CLOCK and the data signal terminal DATA of the adjacent controller 100 and / or the adjacent optoelectronic package, and transmit data signals and control signals. The feedback signal terminal C, the power supply terminal VDD and the ground terminal GND of the optoelectronic package are correspondingly connected to the feedback signal terminal C, the power supply terminal VDD and the ground terminal GND of the controller 100 through corresponding buses.

[0066] The connection methods of other optoelectronic packages are the same and will not be described in detail here.

[0067] Through the integrated setting, the external power supply module only needs to lead out the power line and the ground line, and the controller 100 and / or the front-stage optoelectronic package only needs to lead out the signal line and set the feedback line, which are connected to each optoelectronic package in turn. The circuit structure is simple, which reduces the design cost and the process steps.

[0068] In this embodiment, each optoelectronic package can be correspondingly arranged under a keycap and monitor the position status of the keycap. When the keycap is pressed, the light receiving unit in the optoelectronic package sends a trigger signal, prompting the driver module of the set optoelectronic package to drive the light source module to emit light of the corresponding color according to the received light source driving signal, thereby achieving the purpose of colorful backlight.

[0069] The keycaps of the buttons may be mechanically connected to the optoelectronic package, or may have no connection relationship with the optoelectronic package. The specific structure is set according to the requirements.

[0070] In one embodiment, the light receiving unit includes a light receiving chip and a resistor, the anode terminal of the light receiving chip is electrically connected to the power supply terminal VDD of the optoelectronic package, the cathode terminal of the light receiving chip is electrically connected to the first end of the resistor and the connection node is electrically connected to the feedback signal terminal C of the optoelectronic package, and the second end of the resistor is electrically connected to the ground terminal GND of the optoelectronic package.

[0071] In this embodiment, the light emitting unit includes an infrared light emitter or an LED lamp, and the light receiving unit includes a light receiving chip and a resistor, such as Figure 3 As shown, in one embodiment, taking the first sensing module 230 as an example, the first light emitting unit 231 includes a first infrared light emitter F1, and the first light receiving unit 232 includes a first light receiving chip J1 and a first resistor R1. When the key is pressed, the light emitted by the first infrared light emitter F1 is reflected to the first light receiving chip J1 through the keycap 233 or other mechanical structures. The first light receiving chip J1 sends a trigger signal to the controller 100 through the connection node. The controller 100 determines the physical address of the optoelectronic package that sends the trigger signal based on the trigger signal and the transmission time, and outputs a light source driving signal to the driving module in the set optoelectronic package, thereby driving the corresponding light-emitting unit to emit light of the corresponding color.

[0072] like Figure 3 and Figure 4 As shown, in one embodiment, the ground terminal GND of the optoelectronic package extends into the interior of the optoelectronic package. The driver module and resistor R1 are fixed to the ground terminal GND. The power terminal VDD of the optoelectronic package extends into the interior of the optoelectronic package and is adjacent to the ground terminal GND extending into the optoelectronic package. The light source module and the light receiving chip J1 are fixed to the power terminal VDD. The feedback signal terminal C of the optoelectronic package extends into the interior of the optoelectronic package and is adjacent to the power terminal VDD extending into the optoelectronic package. The power terminal VDD extending into the optoelectronic package is located between the ground terminal GND extending into the optoelectronic package and the feedback signal terminal C. This allows the light source module, which is fixed to the power terminal VDD, to be located in the center of the optoelectronic package, facilitating wire bonding between the light source module and the driver module, ensuring uniform light output. The feedback signal terminal extending into the optoelectronic package is located between the resistor R1 and the light receiving chip J1, facilitating electrical connection of the feedback signal terminal extending into the optoelectronic package to the resistor R1 and the light receiving chip J1 via wire bonding. This arrangement of components within the optoelectronic package fully utilizes the internal space of the optoelectronic package, reducing the size of the package.

[0073] In this embodiment, each optoelectronic package includes a clock signal terminal CLOCK-IN / CLOCK-OUT, a data signal terminal DATA-IN / DATA-OUT, a feedback signal terminal C, a power supply terminal VDD and a ground terminal GND, and a spare signal terminal P is also provided. The clock signal terminal CLOCK-IN is used to input a clock signal, the clock signal terminal CLOCK-OUT is used to output a clock signal, the data signal terminal DATA-IN is used to input a data signal, the data signal terminal DATA-OUT is used to output a data signal, and the feedback signal terminal is used to output a trigger signal.

[0074] Taking the first optoelectronic package 200 as an example, the first driver module 210 and the first resistor R1 are fixed to the extension of the ground terminal GND. The first driver module 210 is respectively connected to the clock signal terminal CLOCK-IN / CLOCK-OUT, the data signal terminal DATA-IN / DATA-OUT, the power terminal VDD, the first LED lamp F1 of the first light emitting unit 231 and the light source module 220 through bonding wires. The light source module 220 includes RGB three-color lamps, which are fixed to the extension of the power terminal. The feedback signal terminal C extends to the interior of the optoelectronic package. The first light receiving chip J1 is fixed to the extension of the power terminal VDD, and the extension of the feedback signal terminal C is located between the first light receiving chip J1 and the first resistor R1. The first resistor R1 and the first light receiving chip J1 are electrically connected to the extension of the feedback signal terminal C through bonding wires.

[0075] like Figure 6 As shown, in one embodiment, the light emitting unit and the light receiving unit are arranged side by side, an opaque partition is arranged between the light receiving unit and the light emitting unit, and an opaque enclosure is also arranged around the light receiving unit and the light emitting unit to isolate ambient light.

[0076] In this embodiment, taking the first light receiving unit 232 and the first light emitting unit 231 as an example, a first opaque partition 234 is arranged between the first light receiving unit 232 and the first light emitting unit 231, and a first opaque enclosure 235 is arranged around the first light receiving unit 232 and the first light emitting unit 231. The first opaque partition 234 and the first opaque enclosure 235 are set as retaining walls for the first light receiving unit 232 and the first light emitting unit 231 to prevent the light emitted by the first light emitting unit 231 from scattering to the first light receiving unit 232 and the external ambient light from scattering to the first light receiving unit 232, causing the first light receiving unit 232 to be triggered incorrectly.

[0077] Other light-receiving units and light-emitting units are also provided with light-proof partitions and light-proof enclosures, which will not be described in detail here.
