Embodiment Construction

[0018] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] A method for displaying data processing, the method comprising the steps of:

[0020] Receive display data to be processed;

[0021] Analyze and process the received display data, generate displayable pixel data and output it;

[0022] In a certain display cycle, the first buffer unit is receiving a frame of pixel data output, and the second buffer unit has completed receiving another frame of pixel data and is displaying it; in the next display cycle, the second buffer unit is receiving a frame of pixel data data, the first buffer unit completes receiving another frame of output pixel d...

Abstract

The invention provides a display data processing method. The method comprises steps as follows: display data to be processed is received; the received display data is analyzed to generate pixel data for display, and the pixel data is output; in a certain display cycle, a first cache unit is receiving one frame of output pixel data, and a second cache unit finishes the receiving of another frame of pixel data and is displaying the pixel data; and in the next display cycle, the second cache unit is receiving one frame of output pixel data, and the first cache unit finishes the receiving of another frame of pixel data and is displaying the pixel data. The invention also provides a display data processing system. By using the display data processing method and system, pixel data stored in the first cache unit and pixel data stored in the second cache unit are stored an displayed alternately; and data displayed in each cycle is complete data on the whole screen, thereby saving the data transmission time, and avoiding ghosting phenomena caused by overlapping with the next frame of data.

Description

technical field [0001] The invention belongs to the display field, and in particular relates to a method and system for processing transmission data in a stereoscopic television. Background technique [0002] Existing TVs are mostly scanned in a progressive manner, and the data transmission and display methods are: display while transmitting. The inventor of the present invention found after research that data transmission will take up a considerable part of the time. [0003] For example, for a display with a refresh rate of 120Hz, within 1 / 120=8.333 milliseconds, according to the specifications of a general display, the display data is output to the display through a low-voltage differential signal (LVDS) bus or other buses. The time occupied by the display screen is generally about 5 milliseconds, and the response time of the screen is generally 6.5 milliseconds, that is, it takes about 6.5 milliseconds from the completion of pixel data writing to the full display. The re...
