Class Overview

LiveDisplay is an advanced set of features for improving display quality under various ambient conditions. The backend service is constructed with a set of LiveDisplayFeatures which provide capabilities such as outdoor mode, night mode, and calibration. It interacts with CMHardwareService to relay changes down to the lower layers. Multiple adaptive modes are supported, and various hardware features such as CABC, ACO and color enhancement are also managed by LiveDisplay.

Public Methods

public float[] getColorAdjustment ()

Added in API level 6

public LiveDisplayConfig getConfig ()

Added in API level 6

Gets the static configuration and settings.

Returns
  • the configuration

public int getDayColorTemperature ()

Returns
  • HSIC object with current settings

public boolean isAutoContrastEnabled ()

Added in API level 6

Checks if the auto contrast optimization feature is enabled.

Returns
  • true if enabled

public boolean isAutomaticOutdoorModeEnabled ()

Checks if outdoor mode should be enabled automatically when under extremely high ambient light. This is typically around 12000 lux.

Returns
  • if outdoor conditions should be detected

public boolean isCABCEnabled ()

Added in API level 6

Checks if the CABC feature is enabled

Returns
  • true if enabled

public boolean isColorEnhancementEnabled ()

Added in API level 6

Checks if the color enhancement feature is enabled

  • true if enabled

public boolean setAutoContrastEnabled (boolean enabled)

Added in API level 6

Sets the state of auto contrast optimization

Returns
  • true if state was changed

public boolean setAutomaticOutdoorModeEnabled (boolean enabled)

Added in API level 6

Enables automatic detection of outdoor conditions. Outdoor mode is triggered when high ambient light is detected and it's not night.

Returns
  • true if state was changed

public boolean setCABCEnabled (boolean enabled)

Added in API level 6

Sets the state of CABC

Returns
  • true if state was changed

public boolean setColorAdjustment (float[] adj)

Added in API level 6

Sets the color adjustment to use. This can be set by the user to calibrate their screen. This should be sent in the format { R, G, B } as floats from 0 to 1. A setting of { 1.0, 1.0, 1.0 } means that no adjustment is made. The hardware implementation may refuse certain values which make the display unreadable, such as { 0, 0, 0 }. This calibration will be combined with other internal adjustments, such as night mode, if necessary.

Returns
  • true if state was changed

public boolean setColorEnhancementEnabled (boolean enabled)

Added in API level 6

Sets the state of color enhancement

Returns
  • true if state was changed

public boolean setDayColorTemperature (int temperature)

Added in API level 6

Sets the color temperature to use in the daytime.

Returns
  • true if state was changed

public boolean setMode (int mode)

Added in API level 6

Selects a new adaptive mode.

Returns
  • true if the mode was selected

public boolean setNightColorTemperature (int temperature)

Added in API level 6

Sets the color temperature to use at night.

Returns
  • true if state was changed

public boolean setPictureAdjustment (HSIC hsic)

Added in API level 6

Sets a new picture adjustment

Returns
  • true if success
