Problems solved by technology

The EDID table used by TV manufacturers adopts a general design method based on each solution platform, that is, the screens of different sizes equipped with the movement all use the same EDID table. After the first round of closed loop, the content of the EDID table is basically the same will be changed again, then this movement will be equipped with multiple screens of different sizes after mass production, resulting in that the parameters related to the screen configuration in the EDID table do not correspond to the actual screen configuration (the screen size and resolution do not correspond) and the production The date is too early, the name of the display does not match, etc., resulting in user complaints

Embodiment 1

[0054] For this example, see figure 1 , showing that a method for updating EDID data includes the following steps:

[0055] Step S100: Obtain hardware information of the smart TV.

[0056] In the process of updating the EDID data, the hardware information of the smart TV can be obtained first, for example, the index value information corresponding to the current display screen of the smart TV and the model information of the current core of the smart TV. It should be understood that when a smart TV is updated, the corresponding display screen may be replaced, or the current core may be upgraded, but generally the HDMI interface will be used, and the initial EDID data corresponding to the HDMI interface needs to be based on the current display screen of the smart TV and The current movement is modified accordingly.

[0057] Step S200: Determine the corresponding configuration information file pre-stored in the storage partition of the smart TV according to the hardware inform...

Embodiment 2

[0068] For this example, see figure 2 , showing that when the hardware information is the index value of the current display screen of the smart TV, a basic EDID data update method includes the following steps:

[0069] Step S210: Obtain the screen parameter information corresponding to the index value from the screen parameter file pre-stored in the storage partition of the smart TV core.

[0070] The screen parameter information includes the model name, manufacturer, width, height, color and resolution of the smart TV display screen.

[0071] It can be understood that the same type of smart TV core can be configured with multiple types of display screens, and the corresponding index values ​​and corresponding screen parameter information of multiple types of display screens can be recorded in the pre-stored screen parameter file. In the process of updating the basic EDID data, the screen parameter information corresponding to the index value is obtained from the screen par...

Embodiment 3

[0086] For this example, see image 3 , showing that when the hardware information is the model information of the current core of the smart TV, the extended EDID data update method includes the following steps:

[0087] Step S220: Obtain the configuration file corresponding to the model information from the feature folder pre-stored in the storage partition of the smart TV core.

[0088] Exemplarily, the configuration file can be general_config.xml, and its storage path can be / system / pcfg / movement_model / config / general_config.xml, that is, the feature folder is the pcfg folder, and the feature folder is located as pcfg Finally, the "Movement_Model" folder can be further determined according to the model information of the current core of the smart TV, and then the corresponding configuration file can be determined.

[0089] Exemplarily, the configuration file general_config.xml includes the following information:

[0090]

[0091] Step S221: Parse the configuration file t...

Abstract

Embodiments of the present invention disclose an EDID data update method, device, smart TV, and readable storage medium. The method includes hardware information of the smart TV; the corresponding configuration pre-stored in the storage partition of the smart TV is determined according to the hardware information information file; determine the update position of the initial EDID data according to the update content recorded in the configuration information file; when the update content is inconsistent with the original content on the update position, update the update content according to the update content and the update position Describe the initial EDID data. The technical solution determines the update content of the EDID data and the corresponding update position according to the hardware information of the smart TV, realizes the automatic update of the EDID data, and effectively solves the problem that the parameters of the EDID initial data and the hardware information of the smart TV do not match.

Description

technical field [0001] The invention relates to the field of smart TVs, in particular to an EDID data update method and device, a smart TV and a readable storage medium. Background technique [0002] EDID (Extended Display Identification Data, Extended Display Identification Data) is a VESA (Video Electronics Standards Association, Video Electronics Standards Association) standard data format, which contains parameters of TV performance, including manufacturer information, maximum image size, Information such as color settings, frequency range limits, and the name of the display. The EDID table used by TV manufacturers adopts a general design method based on each solution platform, that is, the screens of different sizes equipped with the movement all use the same EDID table. After the first round of closed loop, the content of the EDID table is basically the same will be changed again, then this movement will be equipped with multiple screens of different sizes after mass ...
