Here, the first format command is a USB command, and the second format command is a UART command.

After that, in step S225, the second format command is transmitted to the display driving chip 141 via the second interface device 143, so that the display driving chip 141 modifies the corresponding parameter setting value according to the second format command and adjusts the presentation effect of the display 140 correspondingly. . The parameter settings include at least one of contrast, brightness, signal source, and scene mode.

Taking the handheld electronic device 110 as a mobile phone as an example, the software interface of the mobile phone is used in a ready-to-use manner, and the user can control the parameter settings of the display through the mobile phone. For example, FIGS. 3A to 3C are schematic diagrams of an operation interface of a handheld electronic device according to an embodiment of the present invention.

In FIG. 3A, the handheld electronic device 110 displays a contrast and brightness adjustment screen 310. The contrast and brightness adjustment screen 310 includes a contrast value adjustment column 311 and a brightness value adjustment column 312. The user can adjust the contrast value of the display 140 through the contrast value adjustment column 311, and adjust the brightness value of the display 140 through the brightness value adjustment column 312. In FIG. 3B, the handheld electronic device 110 displays a signal source selection screen 320. The user can choose from three source options in the signal source selection screen 320. In FIG. 3C, the handheld electronic device 110 displays a scenario selection mode screen 330. The context selection mode screen 330 includes 4 defined context modes and 3 mode options for user-defined. The user can choose among these scenario modes.

After the handheld electronic device 110 detects the selection in the screen, the parameter setting module 111 will transmit the corresponding control command to the host 120 based on a predefined protocol, and then as shown in steps S215 to S225, the display 140 will modify the corresponding Set the parameter and adjust its rendering effect.

In summary, the present invention uses a handheld electronic device to control the image effect presented by the display, and can adjust the parameter setting value of the display in time. According to this, when the user is currently performing an action that requires the entire display screen of the display to be presented, such as during a game, the user can use the handheld electronic device to adjust the parameter settings such as brightness and contrast of the display without the need to The monitor displays the OSD menu for adjustment. Therefore, the display screen of the monitor will not be occupied when adjusting the parameter setting value, which is more convenient in use.
