Description
Technical Field
The invention relates to the technical field of televisions, in particular to a power-off compensation method of an OLED television and the OLED television.
Background
At present, an Organic Light-Emitting Diode (OLED) television is an Organic self-luminous television without a backlight source, and compared with an LED television, the OLED television has ultrahigh contrast, a wider viewing angle, high dynamic response time, and extremely Light and thin, and is therefore called a third generation novel display technology, and has been widely used in the field of televisions and mobile phones.
Since the OLED television displays by driving the organic light emitting diode to emit light through the TFT (thin film transistor), the TFT characteristics may be shifted after a long time operation, thereby generating a residual image. In the most effective design for preventing and eliminating the afterimage of the OLED television in the industry, TFT compensation is performed on the television at regular time after standby through a compensation algorithm, but obviously the design is limited by the use habit of a user, and if the power is directly cut off when the user does not watch, the TFT compensation cannot be performed on the television.
The method for preventing and repairing the afterimage comprises the steps that under the condition that the television is continuously kept powered on, when a user operates the television to be in a standby state, an SOC system judges whether screen maintenance is needed to repair the afterimage, if yes, an afterimage compensation algorithm is used for compensation and repair, and the standby state is started after the afterimage compensation algorithm is completed. If the using time length condition that the screen needs to be maintained is met, but the standby screen cannot be maintained due to the fact that the user pulls out the power, the television pops up a prompt to suggest the user to perform standby screen maintenance when the user starts the television next time.
The design of the standby ghost compensation is limited by the use habit of the user. The current common use habit of users is to directly cut off the power supply when the users do not watch the television, so that the television system can not carry out the ghost compensation, and the ghost problem can occur when the users watch the OLED television for a long time; if the user is reminded that the television needs to be maintained when the using time of the television reaches the time requirement of compensation and repair, the user is easily ignored and the using experience of the user is affected, and in conclusion, a plurality of problems such as user complaints are easily caused.
Accordingly, the prior art is yet to be improved and developed.
