HTC Sensation SLCD manufactured by 2 companies

The SLCD displays on the HTC Sensation are manufactured by 2 companies namely Sharp and Acer. The latter was commonly found in many HTC Sensation, which is also suspected to have manufacturing defects leading to the infamous dust under the screen problem. However, the Acer display gives a whiter white than the Sharp display. It also maintain the colour when viewed at an angle. Many HTC Sensation which have been sent in to HTC for a screen replacement had their screens replaced with Sharp displays. The move to Sharp displays may probably did not solve the dust issue. There is also noticeable improvement in contrast and flickering when compared to Acer's. Severe flickering as seen on Acer displays are not present in Sharp displays. However, do note that the Sharp display has a serious colour shift when viewed at an angle. The display suffers a great yellow tint when viewed at an angle and the white is more yellowish compared to Acer's. Head on past the break for more info and the workaround to adjust the colour on Sharp's SLCD.

Acer SLCD
Benefits:

• Whiter white (personal preference)
• Only slight pinkish tint when viewed at an angle

Disadvantages:

• Most likely the reason for dust problem
• Lower contrast compared to Sharp
• Text flickering is severe especially when white text on black
• Ghosting is said to occur as well
• Said to have pixelation issues

Sharp SLCD

Benefits:

• Warmer white (personal preference)
• Higher contrast Mixed reactions. Some say Acer has better blacks while some say Sharp does it better
• Text flickering is minimal or does not occur at all
• Said to be sharper

Disadvantages:

• Colours are overly warm which makes white looks like yellow
• Severe fluorescence yellow tint when viewed at an angle
• On our unit particularly, a touchscreen issue occured after having been replaced
• After a couple of months on the Sharp display, it was realised that dust enters the screen after all.

To check which display you have, download Terminal Emulator (Free from Market) and key in dmesg

Look for the line: Panel Type = PANEL_ID_PYD_

Whereby AUO means Acer and SHARP means Sharp.

For people with the Sharp SLCD and wants a cooler colour tone, download

Screen Adjuster 1.6

and increase the blue value for your display. This should improve the yellowing issue.
