Fig. 1 to 3 show a specific embodiment of the handheld control box 100 for dot screen detection according to the present application, where the handheld control box 100 includes a housing 1, a display screen 6 disposed on a surface of the housing 1, and a circuit component disposed in the housing 1.
The housing 1 includes an upper cover made of a plastic material and a back plate made of a plastic material, the upper cover and the back plate are detachably connected by a plurality of screws, and an accommodating space is formed between the upper cover and the back plate. The housing 1 has a rectangular parallelepiped outer contour and a small size, and preferably has a length of 220mm or less, a width of 150mm or less, and a thickness of 30mm or less, so that it is suitable for a worker to hold it with both hands or one hand. In the embodiment shown in fig. 1 in particular, the housing 1 has a length of 205mm, a width of 135mm and a thickness of 27mm.
A display screen 6 is exposed from the surface of the upper cover of the housing 1 for displaying the graphic information. The circuit assembly is disposed in the accommodating space of the housing 1 and fixed to the upper cover.
The circuit assembly comprises a PCB board, and a LAN communication module 2, a DDR cache module 3, a storage module 4 and a control module 5 which are arranged on the PCB board, wherein:
the LAN communication module 2 includes a communication interface 201 (i.e., a LAN interface or a network port) exposed from a surface of the housing 1. The communication interface 201 is used for connecting a PC or an image generator. That is, the communication interface 201 may be used to connect a PC (Personal Computer) or a graphics Generator (PG), but the communication interface 201 does not connect the PC and the graphics Generator at the same time.
The control module 5 is respectively connected with the LAN communication module 2, the storage module 4 and the DDR cache module 3, and the control module 5 is used for: when the communication interface 201 is connected with a PC, the LAN communication module 2 is controlled to receive point screen data from the PC and write the received point screen data into the storage module 4; when the communication interface 201 is connected to the image generator, the DDR cache module 3 is controlled to read dot screen data from the memory module 4 (the dot screen data in the memory module 4 enters the DDR cache module 3 via the control module 5), and the read dot screen data is sent to the image generator via the LAN communication module 2.
In practical application, a worker can connect the communication interface 201 on the handheld control box 100 to a PC through a LAN cable, and perform related operations on the handheld control box 100, so that the control module 5 controls the LAN communication module 2 to receive point screen data (the point screen data generally includes image data and parameter data of a display module) corresponding to multiple models of display modules (the display screen 6) from the PC, and writes the point screen data received by the LAN communication module 2 into the storage module 4, thereby storing the point screen data capable of lighting the display modules of the various models in the storage module 4 of the handheld control box 100, then taking down a network cable connecting the PC and the handheld control box 100, and the handheld control box 100 is in a standby state at any time. When some display module needs to be subjected to point screen detection, a worker only needs to connect the communication interface 201 of the handheld control box 100 to the image generator through a network cable, connect the image generator to the display module, and perform related operations on the control box, so that the control module 5 controls the DDR cache module 3 to read point screen data corresponding to the display module from the storage module 4, and send the point screen data read by the DDR cache module 3 to the image generator through the LAN communication module 2, thereby enabling the image generator to light the display module based on the point screen data obtained by the image generator, and performing Automatic Optical Inspection (AOI) on the display module.
The DDR cache module 3 can quickly read the dot screen data in the storage module 4 and cache the read dot screen data in real time, so that the dot screen data can be continuously and stably transmitted to the image generator through the LAN communication module. The main function of the image generator is to transmit the image signal, which is configured by the image data received by the image generator into a target format (such as HDMI format or VBO format), to the adapted display module, and therefore, the image generator is also referred to as an image signal conversion device in the industry.
It can be understood that lighting up display modules of different models requires different point screen data, and in order for the handheld control box 100 to be able to store a large amount of point screen data in the storage module 4 of the handheld control box 100 for display modules of various models. The capacity of the memory module 4 must therefore be large enough, generally not to be less than 1TB (terabyte).
The memory module 4, the DDR cache module 3 and the control chip may be three or three independent chips. Specifically, in this embodiment, the storage module 4 is specifically an SSD storage chip, and the control module 5 is a microcontroller chip. In other embodiments, the control module 5 may also be an FPGA chip or a single chip.
In this embodiment, the display screen 6 is a touch display screen 6, and the control module 5 is connected to the touch display screen 6. The touch display screen 6 can receive a touch operation of a user to generate an instruction sent to the control module 5, and the control module 5 receives the instruction to control the handheld control box 100 to perform a corresponding action. Specifically, the control module 5 is configured to:

on the other hand, when the communication interface 201 is connected to the image generator, in response to a second touch operation of the user on the touch display screen 6, the DDR cache module 3 is controlled to read the dot screen data from the memory module 4 and transmit the read dot screen data to the image generator via the LAN communication module 2.
Referring to fig. 5 and fig. 6 in combination with fig. 4, in another embodiment, the display screen 6 of the handheld control box 100 is a common display screen 6 that is not capable of performing touch operation, in order to enable the handheld control box 100 to receive and respond to the operation of the user, the handheld control box is configured with a plurality of physical keys 7 exposed from the surface of the housing 1, and the control module 5 is connected to the physical keys 7. The physical key 7 can receive a pressing operation of a user to generate an instruction sent to the control module 5, and the control module 5 receives the instruction to control the handheld control box 100 to perform a corresponding action. In particular, the control module 5 is configured to:
on one hand, when the communication interface 201 is connected with a PC, the LAN communication module 2 is controlled to receive point screen data from the PC and write the received point screen data into the storage module 4 in response to the pressing operation of at least one first entity key in the entity keys 7 by a user;
on the other hand, when the communication interface 201 is connected to the image generator, in response to a user's pressing operation of at least one second physical key of the plurality of physical keys 7, the DDR cache module 3 is controlled to read the dot screen data from the memory module 4 and transmit the read dot screen data to the image generator via the LAN communication module 2.
In other embodiments, when the handheld controller is shipped from a factory, the manufacturer has pre-stored the dot screen data corresponding to various models of display modules in its storage module 4. Therefore, in the subsequent use process, a user does not need to obtain corresponding point screen data from a PC, and only needs to connect the communication interface 201 of the handheld controller to the image generator by means of the LAN cable and transmit the point screen data corresponding to the current display module to be tested to the image generator.
The embodiment of the present application further provides a dot screen device, which includes an image generator and a handheld control box 100. The handheld control box 100 adopts the structure shown in fig. 2 or fig. 5. The image generator comprises a signal output terminal used for connecting the display module and a second LAN communication module with a second communication interface. The second communication interface is exposed from the surface of the image generator, and is used for connecting the communication interface 201 of the handheld control box 100 through a LAN cable under the condition that the communication interface 201 of the handheld control box 100 is not connected with a PC, so as to receive the dot screen data transmitted by the handheld control box 100. The signal output terminal is used for transmitting the image data processed by the image generator (for example, the initial image data sent by the handheld control box 100 is configured into a data format required by the display module) to the display module, so as to realize the dot screen of the display module. The signal output terminals of the image generator are usually provided in plurality, and some terminals are HDMI terminals that output HDMI signals, some terminals are VBO terminals that output VBO signals, and the like.
It should be noted that, in the above-mentioned handheld control box 100 provided in this embodiment of the present application, the modules therein may work in combination with software in the prior art, for example, the technology itself for receiving or sending data through the LAN communication module 2, and the technology itself for controlling the LAN communication module 2, the storage module, and the DDR cache module 3 to perform data interaction through the control module 5 are all the prior art, and therefore, this application does not relate to software improvement.
