In the embodiment of the present invention, the dot screen component may include a motherboard, or the dot screen component may include a motherboard and a timing controller. In response to the difference between the dot screen assemblies, the connection relationship between the display adapter 10 and the dot screen assembly 20 provided by the embodiment of the present invention may include the following two aspects:
in a first aspect: referring to fig. 7, a schematic structural diagram of a liquid crystal display device according to an embodiment of the invention is shown, and fig. 7 illustrates an example in which a dot panel assembly 20 includes a main board 21. Referring to fig. 7, an input terminal (not shown in fig. 7) of the display adapter 10 is connected to an output terminal (not shown in fig. 7) of the main board 21, an output terminal (not shown in fig. 7) of the display adapter 10 is connected to an input terminal (not shown in fig. 7) of the timing controller 40, and an output terminal of the timing controller 40 is connected to the liquid crystal display 30. In the embodiment of the present invention, referring to the above description of the structure of the display adapter 10, an input terminal of the display adapter 10 is connected to an output terminal of the main board 21, that is, an input terminal of a first adapting unit (not shown in fig. 7) of the display adapter 10 is connected to an output terminal of the main board 21, and an output terminal of the display adapter 10 is connected to an input terminal of the timing controller 40, that is, an output terminal of a second adapting unit (not shown in fig. 7) of the display adapter 10 is connected to an input terminal of the timing controller 40. The display adaptor 10 may receive the dot screen signal output by the output terminal of the main board 21, process the dot screen signal according to the pin definition of the input terminal of the timing controller 40 to obtain a processed dot screen signal, where the processed dot screen signal matches the pin definition of the input terminal of the timing controller 40. Thus, the lighting signal can reach the timing controller 40 through the main board 21 and the display adapter 10, and reach the liquid crystal display 30 through the timing controller 40 to light the liquid crystal display 30.
For example, assuming that the dot screen signal output by the motherboard 21 is "01110", and the pin at the input of the timing controller 40 is defined as "00111" (that is, the defined signal that the pin at the input of the timing controller 40 can receive is "00111"), after the display adapter 10 receives the dot screen signal "01110" output by the motherboard 21, the dot screen signal "01110" is processed according to the pin definition at the input of the timing controller 40, so as to obtain a processed dot screen signal, which may be "00111", and the processed dot screen signal matches the pin definition at the input of the timing controller 40, so that the processed dot screen signal "00111" can reach the timing controller 40 through the motherboard 21 and the display adapter 10, and reach the liquid crystal display 30 through the timing controller 40, so as to light the liquid crystal display 30.
In a second aspect: referring to fig. 8, which shows a schematic structural diagram of another lcd device according to an embodiment of the present invention, referring to fig. 8, the dot panel assembly 20 is illustrated as including a main board 21 and a timing controller 22, where an output terminal (not shown in fig. 7) of the main board 21 is connected to an input terminal (not shown in fig. 7) of the timing controller 22, an input terminal (not shown in fig. 7) of the display adapter 10 is connected to an output terminal (not shown in fig. 7) of the timing controller 22, and an output terminal (not shown in fig. 7) of the display adapter 10 is connected to an input terminal (not shown in fig. 7) of the lcd panel 30. In the embodiment of the present invention, as can be seen from the above description of the structure of the display adapter 10, the input terminal of the display adapter 10 is connected to the output terminal of the timing controller 22, that is, the input terminal of the first adapting unit (not shown in fig. 8) of the display adapter 10 is connected to the output terminal of the timing controller 22, and the output terminal of the display adapter 10 is connected to the input terminal of the liquid crystal display 30, that is, the output terminal of the second adapting unit (not shown in fig. 8) of the display adapter 10 is connected to the input terminal of the liquid crystal display 30.
The display adapter 10 may receive the dot screen signal output by the timing controller 22, process the dot screen signal according to the pin definition of the input terminal of the liquid crystal display 30 to obtain a processed dot screen signal, and the processed dot screen signal matches with the pin definition of the input terminal of the liquid crystal display 30, so that the dot screen signal can reach the liquid crystal display 30 through the timing controller 22 and the display adapter 10 to light up the liquid crystal display 30.
For example, assuming that the dot screen signal output by the timing controller 22 is "01110", and the pin of the input terminal of the liquid crystal display 30 is defined as "10011" (that is, the signal that can be received by the pin of the input terminal of the liquid crystal display 30 is defined as "10011"), after the display adapter 10 receives the dot screen signal "01110" output by the timing controller 22, the display adapter 10 processes the dot screen signal "01110" according to the pin definition of the input terminal of the liquid crystal display 30 to obtain a processed dot screen signal, where the processed dot screen signal may be "10011", and the processed dot screen signal "10011" matches the pin definition of the input terminal of the liquid crystal display 30, so that the processed dot screen signal "10011" can reach the liquid crystal display 30 through the timing controller 22 and the display adapter 10 to light the liquid crystal display 30.
It should be noted that, in practical application, display adapters may be respectively disposed between the motherboard and the timing controller and between the timing controller and the liquid crystal display, assuming that the display adapter disposed between the motherboard and the timing controller is a first display adapter and the display adapter disposed between the timing controller and the liquid crystal display is a second display adapter, the first display adapter may process the dot screen signal transmitted by the motherboard according to the pin definition of the timing controller, so that the processed dot screen signal matches the pin definition of the timing controller, and then the processed dot screen signal reaches the second display adapter through the first display adapter and the timing controller, and the second display adapter may process the dot screen signal transmitted by the timing controller according to the pin definition of the liquid crystal display, so that the processed dot screen signal matches the pin definition of the liquid crystal display, thereby enabling the screen lighting signal to reach the liquid crystal display screen and lighting the liquid crystal display screen.
It should be noted that, in practical applications, the lcd is usually lighted by a specific lighting signal, so the compatibility of the lcd is poor, but after the display adapter processes the lighting signal, the processed lighting signal can light the lcd with poor compatibility, so that the compatibility of the lcd is enhanced. For example, assuming that there are a liquid crystal display Q and a liquid crystal display O, the lighting signal L can light the liquid crystal display Q but cannot light the liquid crystal display O, and when the display adapter provided in the embodiment of the present invention is disposed at the input end of the liquid crystal display O, the display adapter processes the lighting signal L, and then the processed lighting signal L can light the liquid crystal display O.
At present, with the continuous expansion of the application occasions of the liquid crystal display screen, new products and new technologies are developed more and more rapidly. The upgrading and upgrading of LCD display products (such as liquid crystal display screens) of the same model, the LCD display products with different sizes and similar driving schemes or the LCD display products with the same specification of different manufacturers often cause the problem that the LCD display products cannot be lightened only due to the difference of pin definitions of the LCD display products, and the product compatibility is poor, so that the old products cannot be used after the upgrading and upgrading of the products, thereby influencing the customer experience; in research and development, poor product compatibility can also cause difficulty in new technology verification and a great deal of repetition of basic research and development work, and the development cost and schedule are influenced. The display adapter provided by the embodiment of the invention has higher compatibility, reduces the lighting difficulty of the liquid crystal display screen, is not only beneficial to upgrading and upgrading of civil products, but also beneficial to reverse development and technical development in LCD display research and development work, and can save a large amount of time and cost.
In summary, in the display adapter provided in the embodiment of the present invention, the adapter module of the display adapter can receive the dot screen signal output by the output end of the dot screen assembly, process the dot screen signal according to the pin definition of the input end of the liquid crystal display screen to obtain the processed dot screen signal, and the processed dot screen signal matches with the pin definition of the input end of the liquid crystal display screen, so that the problem that the liquid crystal display screen cannot be lit due to the fact that the dot screen signal cannot drive the liquid crystal display screen is solved, and the situation that the liquid crystal display screen cannot be lit is avoided.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
