Problems solved by technology

[0003] Generally speaking, in order to avoid image sticking, LCD monitors usually enter standby mode or animation mode after being idle for a period of time to prevent liquid crystal molecules from being continuously driven by the same driving voltage, but this method of avoiding image sticking is not suitable for use For electronic products that need to display the same screen for a long time, such as a wearable mobile device display that is displayed on a liquid crystal display, a smart watch is one example

Embodiment Construction

[0023] figure 1 It is a schematic circuit block diagram of a transflective display device according to an embodiment of the present invention. Such as figure 1 As shown, the transflective display device 100 includes a transflective display panel 10 , a scan driver 20 , a data driver 30 , a timing controller 40 and a backlight module 50 . The transflective display panel 10 includes a plurality of pixels 101, each pixel 101 includes a plurality of sub-pixels 1011 of different colors, and each sub-pixel 1011 has a transmissive area 1012 (shown in image 3 , Figure 4 , will be described in detail later) and the reflection area 1013 (shown in image 3 , Figure 4 , will be detailed later). The scan driver 20 is electrically coupled to each sub-pixel 1011 through a plurality of scan lines 21 . The data driver 30 is electrically coupled to each sub-pixel 1011 through a plurality of data lines 31 . The timing control circuit 40 is electrically coupled to the scan driver 20 , t...

Abstract

The invention discloses a half-reversible display device and an operation method thereof; the half-reversible display device comprises a half-reversible display panel and a backlight module; the half-reversible display panel comprises a plurality of pixels; each pixel comprises a plurality of sub-pixels in different colors; each sub-pixel respectively is provided with a penetration zone and a reflection zone; the operation method of the half-reversible display comprises the following steps: determining whether the half-reversible display enters a reflection zone operation mode or not; when the half-reversible display enters the reflection zone operation mode, a mode in which at least one sub-pixel of each pixel is driven in each time is used to drive the half-reversible display, and the backlight module is shut, so the reflection zone of the driven sub-pixel can be used to reflect an environment light source of the half-reversible display for displaying.

Description

technical field [0001] The present invention relates to a display device and its operating method, in particular to a transflective display device and its operating method. Background technique [0002] Most of the electronic products currently on the market use liquid crystal displays as components for displaying images. However, limited by the material characteristics of liquid crystal molecules, when the liquid crystal display allows the liquid crystal molecules in each pixel to be driven by the same driving voltage for a long time in order to continuously display the same picture, the liquid crystal display will display the next picture. Sometimes the image of the last frame will remain on the screen, which is the so-called image sticking (IS) phenomenon. [0003] Generally speaking, in order to avoid image retention, LCD monitors usually enter standby mode or animation mode after being idle for a period of time to prevent liquid crystal molecules from being continuousl...
